Good Box

Great box does well with my subs would buy again

Heavy Duty!

I would recommend this product for the guy's out there that are serious about their music. If you got good, high quality subs, then this box will make them perform to your sub's max output with out worry of blowing up your box.

good box

I bought this box for 2 12" kicker cvx subs 750 watts a piece its a great closed box for them especially stuffed 1/4 with pillow stuffing.. looks real good to.. quick shipping

good value

product worked for my new hifonics subs. that will be a winter system for my ride so i don't have to keep my main subs in all year round. i really like it mostly because its has black carpeting.

The Box that Rocks

Appears to be fairly well built. Arrived with a little dent and a tear but its too little to bother with. Sounds nice but doesn't hit as deep as I would have liked. Small size however, leaves me some room for a couple of bags of groceries. Three stars for durability since I've only owned this for about a month.

Amazing Enclosure, Even Better Price.

Ordered this as my first enclosure, put two 12" subs in it and I haven't found a box that hits as hard and as clean as this one has. Will definitely buy from SonicElectronix again for my car audio needs.

great box

Very sturdy well built. Allows maximum bang. Great price under $60

Fast and easy great buy

I got my complete set up: 12" kicker subs box 1000watt Mbquart amp and amp kit. I have always installed my own equipment, I found it helpful that they have videos that covered some of the product they carry. There are a few shop's in Texas like Best buy and Custom Sounds that offer equipment. But the professionalism of the knowledgeable staff the price and the reliability made it clear that I wanted to do business with them.

solid sealed box!!!

Cant beat the price. But it is really very good box. I put two 12" hifonic,also bought from here, with a 2 channel 1000 watt amp.It really shook my rearview mirror in my '97 towncar. My brother loved it so we put it in his '92 prelude.Wow!!! You can hear him before you see him. Great buy!!!

Its a box

have kicker 12, they sound alright have some loose paneling in my car, so I'm having trouble getting the clarity I want. over all its a box and it works.

Great box

I have this box with 2 kickers 12 in back of a Nissan altima and they soundgreat. Would recommend to anyone and would definitely buy again. Sonic electronix is the best

Great Box

I ordered this for 2 crunch gpv's about six months ago because I didn't have the tools to properly build my own box. After six months this box is still holding up and works perfect with my subs.

Awesome "BANG" for your buck

I am on a budget, like most of us. I needed a nice looking box for a reasonable price. For $52.00 you can't beat it.
I loaded my 2 12" Alpine TypeS subwoofers in it. Mounted my amp to the back and they are still going strong.

bangn

Love it nice size for my subs still banging the same system

Solid Box

Ok so I bought this box because I wanted a quick sealed enclosure for my 2 JL W3's. The box is made pretty solid, true 3/4 MDF but the caulk job on the inside was kind of off but that's nitpicking. Haha after 3 weeks though of pushing my W3s the top of the box is leaking air. So not the best made but definitely a good pre fab and pretty cheap. Can't really complain. It is nailed together tho so yea..

It's a box without a hole

Solid sealed enclosure. Two of them barely fit in the back of my 02 Focus SVT 3 door. The binding posts are cheap, I tightened them as I would other posts but one out of eight wouldn't tighten because the thread tolerance is poor and it acts like its stripped, I can get some pressure on the wire but I worry it will come loose. Probably worth spending a little more money on a better enclosure but it works fine if you're on a budget.

very good sub box

The box is very good at 1.25 cubic feet. I'm running 2 12's with 800 watts rms and it hasn't shattered. Wish it was 1.35 cubic to accommodate for subwoofer basket displacement but it still makes makes subs hit ridiculously hard. Polyfill helps make the box seem bigger due to mechanics and the "Q" point. I really couldn't be happier!

Great Value!

I ordered this item for my grandson and he loves it.

Good value, good quality

Bought the MDFD12 for my son. Installing the subwoofers was very easy and the enclosure looks great. Highly recommend.

good box

It is a good prefab sealed box. I looks good and is functional.

good box cheap but good

this box is deferentially cheap but i put my 2 kicker comp 12's in there makes the sound good but i am thinking of getting a ported box soon, box is made with good material and i like it have it wired down to 2 ohms its sound good

Belva MDFD12

Belva mdfd12 12" box is good quality and good affordable price really good size an make my subwoofer sound amazing... 5 star

WOW Great Quality

I purchaced your Dual 12" sealed sub enclosure and added two Alpine R's and fosgate 1000w amp and WOW does not even come close, it Rocks. The quality of the box is really really impresive. The carpet in not the junk material I've seen in my other buddies combo's.
When you buy this box you know it will deliver and last a long time.... Sonic, keep up the good work!

Dual 12" 3/4" MDF Sealed Subwoofer Enclosure

If you are looking for a quality made box this is it !! I was very impressed with this box the moment I opened it.

The WOW factor was at least a 10.5 on the 1 to 10 scale. I WILL BUY AGAIN .

quality product

This enclosure is a well built enclosure for sq applications. I purchaced to house 2 CV vmax 122 drivers and the sound quality was almost rubbery? not tinny, never a crackle....fluid almost..... call it a well dampened sound with minimal distortion. just clean bass all the way into the 20s. made sounds i diddnt know existed. if you dont care how your music sounds and just looking for loud, look elsewhere. my only complaint, 11" cutout is too small for the vmax and the black carpet is difficult to follow a line with the router.

Great Sound!

i have 2- 12 inch Memphis audio 15-M3124D's in this box each putting out 2000 watts max hooked up to a MA audio HK10KA amp rated at 10,000 watts max. i have the subs bridged and it has way too much power going to them but the box still stands up. i would recommend that when you install your subs that you put some sort of foam stripping underneath the lip so when you screw it down you wont have and leaks at all.

Sleak, Sexy, Soundiful!

Its cheap, in price. Yeah, we see that. But let your worries go to rest, this is a GREAT BOX. Its well made, and put together great. Although they did use nails instead of screws, if you know what your doing, it won't slow you down. I have 2 12" Kickers in this baby, and pounds like a mofo.

Get this box. You won't be disappointed.

Best box for the price.

good box

I bought this box to house two Pioneer TS-W309D2 subs. Box has a solid construction. I could not feel any air coming from the seams.

GREAY BUY!

I put 2 P3 dual voice 12's in this box and they sound awesome .. cant beat the price.. the quality is there

Great box

Runs 2 Rockford Punchs in and no air leaks and bass is clear as hell. Any 12 would sound great in this box, would buy again if it ever goes bad.

Good product

Built very sturdy except for the terminals. Its easy to switch those out though so no complaints. Thanks Sonic!

A little trouble at first...

The whole was no the size it said it was. I happen to be a part-time handy man so I had a circular sander and was able to make the whoel bigger. Took about an extra 20 mins of work to mount the subs, but overall everythign worked out. No complaints about box. It is doing it's thing!

good cheap starter box

i bought this box about a year ago for 2 of my infinity reference 1260w subwoofers. I have two more in a ported box. im pushing 350w to all 4 and I have to say I like this box more than the ported. you feel it more in the sealed box but lose a little on the db's but its worth it. the box is sturdy and hasn't showed wear a bit. its tuned in the lower 40's so you wont get stupid low with it but can get loud. I would recommend it to anyone on a budget or to lazy to build their own box. it comes with polyfill which is a bonus, the terminals on the back need calked but that's with about any box you buy. overall I like it and would buy again if I had to.

soso box!

Nice and built! really small box, has nice and deep sound... but the 12in kicker crvs need more space I think

Great box

Great box for the price and it can fit in any trunk.

great!!!!!

was just the right amount of space i needed for the 12's

ok so far

Installed this weekend, I did add a couple pounds of "pillow stuffing" since the box was a tad smaller then what I needed. I have noticed some flex already but im not suprised with the subs that are in it. I will add triangle shaped gussets and some "trim screw" to try and hold things together.

A sheet of real MDF (not the cheap underlayment) is $32, carpet and glue around $15 so for what they want for this its a good deal that just needs some minor tweaks.

Kick a**

The sub box was really good.

Okay

The box is leaking now. But the price and design was worth it all in all; it's just due to be resealed.

Perfect

Not much else to say besides great product. Shipped in only 3 days, and the pre-done polyfill is a great touch. My only comlaint would be that my car smelled like glue for a few days after I put this box in, but that's just nit-picking. Will definitely order boxes from Sonic in the future!

Sub Enclosure Review

Perfect size to fit my Infinity subs. Wish it came with mounting feet but can't ask for everything. Quality is legit for the price. Just your average rectangular box. Fit in the trunk of my 240sx which is pretty small.

Great Box

Subs fit great and the construction was sound. Thanks Sonic!

GET WHAT YOU PAY FOR!!

This box looked great and felt very durable. My subwoofers wouldnt fit at first so I had to do some shaving, NO PROB. It sounded good for awhile and I loved it. After about two weeks, it lost its sound, went to check out the problem the whole front of the box had almost came off, Box was sealed very well, too bad they used nails instead of screws, would have been a very good box.

Nice Box

This box is pretty clean...nice black fabric, enough to hold the subs and gives them enough air to makes the subs bump and bump and bump and bump! Good buy at an unbeatable price. Awesome.

Great box

This is a great box. I prefer ported but my trunk is too small for it so I had to go with sealed. I'm still happy though. This had the perfect size for my 12s. Also the measurements are a little off. The box is a little bigger that the description said.

Great Subwoofers

Everything was going perfect with the two sub woofers i purchased. Great price & everything. But then someone stole my car & the woofers were in it. Anyways, they were GREAT while I had them.

Great

This is a great sub woofer box for the price it is heavy 41 pounds and it is sturdy. I have 2 12 kickers 600 rms 1500 peak and they sound great in this box hits lows and highs hard. I would say to any one buy it.

Okay Box

had to trim the 12" hole for my Sound stream PCO.12 subs they wouldn't fit at all. once I trimmed the MDF I love this box. they could have used spring term instead of screw though.

By James on June 1, 2015 Verified purchase

Great price for this box, very reliable. I put 2 lanzar 15s in here and they sound great, would highly recommend buying this and not wasting more money on a more expensive box

great box

this box is light weight. its made strong and fits every sub ive ever used in it.

nephew

My nephew loved this product along with the Autotik amp and Kenwood subs for Christmas. I even upgraded my old amp with a 4000 watt PZX Crunch amp to keep up with my nephew and his system lol

nice & clean

I replaced my old box with this 1 & man what a difference. My old box was 11 years old & I didn't realize it was falling apart & with this new box I noticed an instant difference. Its a great box for the price, it holds firm & can handle the full pressure of 1100 RMS

I did have to spray a little adhesive inside for 1 part of the foam & terminals were screwed in & not exactly straight & I also had to poke holes in the foam for wires but these things are no problem. The box is awesome & I will by more in the future

Good bang for the buck

It's tough to build a box for the price you can buy one of these. They are solid. I haven't had any issues with mine.

Good Quality

I would definitely recommend this box to a friend, Nothing like a good old professionally made box, I love the material that they put in it, it really adds to the sound.

Must Have!!!!!

This is an awesome enclosure. The price is very competitive as well. I am running 2 Rockford Fosgate R2D2-12 and there is no distortion at all. It is a very tight, clear sound. I highly recommended for anyone looking for a high quality low cost setup.

Good Sub Box

I like it, I think the covering looked good but I ended up messing it up trying to screw something into the outside. Otherwise i liked the box, my subs hit good in it.

ELW1214.2 BOX

Superb Box! Tight sounding bass, and best of all deep rumbling bass. Excellent for an audiophile like me.
Easy to install and use!

Belva 2 12" sealed enclosure with my 2 12" Infinity Kappas

Great box, holes were perfect sized and nice mounting depth! My triple voice coil Infinity Kappas with the 1600w amp SLAMS!!!!

Subwoofer by Infinity

Very nice sound and handling. shakes the entire car. Would buy from them again.

Love this sub!

I bought one of these off of Ebay a while ago and was extremely pleased with it, so I bought a 2nd one from SonicElectronix during their Black November sale. I built my own custom ported enclosure at 2.0 cubic feet, tuned to 32hz. This sub hits the lows very well and puts out an insane amount of bass for only being a 300w RMS sub. In the enclosure that I built, it actually gives my buddy's 600w rms sub a run for it's money. I would highly recommend this sub to anyone, but also recommend that you look at the suggested enclosure size and don't skimp on a proper enclosure.

Great 12's Box

This box is designed well. It is assembled, sealed, and carpeted very well. Speaker terminals are nice inside and out. Couldnt be any happier with this enclosure. Will use box with various subs.

Excellent!

Cheap and effective! This is truly one of the best boxes that i have bought for the price it is. Sounds great and made very well!

best box 4 the buck

Don't let the skimpy price fool you. This box is made very well and it's ready to go. The joints are already caulked and glued - so there is nothing more to do than mount you speaker.

It's not MDF(medium density fiberboard) like all the others, it is made from HDF; high density fiberboard. HDF boxes are typically stronger, stiffer, and lighter than MDF enclosures. The box does not require any additional bracing because of its density. It has a high an undetectable high frequency resonance and doesn't color the sound of your bass with unwanted buzzing or flexing. The HDF box is lighter than MDF because it has smaller fibers that when pressed and heated require less glue and resin to bind the fibers together.

The speaker terminals are screw type gold plated binding posts that will hold 12 g speaker wire easily. They screw into the enclosure for added strength and a tighter seal.

Just make sure that you do your math and pick the right sub for the cubic feet and stuff with poly fiber fill.

Awesome

Bought this for some 12" audiobahhn subs I bought 2 years ago still brand new in the box and hooked everything up in my 91 civic sedan to my
Hifonics BRX2000.1D Brutus Mono block and pure awesomeness. The box makes these subs slam. Highly recommend this box

Extremely well built

Insanely well built box.

Carpet job is top notch, Good quality carpet stretched perfectly over the box. All joints are glued and caulked well. theres no need for extra bracing here but you may add some 2x4's to reduce the airspace if needed. The gold push terminals are well sealed in place.

Hits low and hard with all sub's I've thrown at it (JL Audio 12W04's, Rockford Fosgate P312D4's, Kicker CVX12's and finally Alpine SWX-1242D's)

Don't be afraid of the price. It's a perfect price for a box of this caliber. Would recommend it to anyone.

Tuff Stuff

Nice heavy, good sounding box. I would reccomend putting some polyfil to "cushion" the backfire of the subwoofer, really helps w/any sealed box and totally makes a valuable difference considering it only costs about 5-10$ more. The box itself is well sealed and well made, the connectors on the inside and out are really easy to use and once connected your wires will stay put.

Good Product Good Box

This box is great for the low! I don't have nothing bad to say about this product.... The sound quality is awesome with this sealed box.

Infinity 1262w

Great sub for the price. I used this with a 300rms MTX amp and it was loud, deep, and clear. Would recommend for sure.

this is a solid box

when i bought this box i wasnt really expecting much, because of the price an all but when i put my rockford fosgates's in it, it did sound great, and let me tell you im gettin 2 12 alpine type r next and im for sure going to be getting this box again.

so dont let the price scare you trust me you wont be disappointed

Good Box

I have this box with two hifonics subs, hooked up too a hifonics 1600 wat amp. Its a very good box and hits really good. Would approve to anyone.

Great Box

This is a well built box. Great quality carpet. If you want a good box without paying high prices this is perfect.

Your basic sealed box

Great box. Quality carpet job, all seams sealed correctly and well, and the terminals are strong and functional. Perfect basic box to make two twelve's hit perfectly. Just remember this is a sealed box, so it will have a differnet sound than that of a ported or bandpass box, but if u want a tighter hitting bass, this box if perfect.

Sound as accurate as JL Audio w1v2's

I was tired of the sloppy sound from my old subs, and I always knew Infinity was known for realistic, accurate bass sound, so I grabbed me two of these and put them in a Sound Ordinance 1.25 cf braced, sealed enclosure. They sound very, very good- just like my JL's in my Explorer... I am driving them with a Rockford Fosgate T1500-1BDcp amp at 4 ohms...a bit much, but they seem to handle that power fine with the gain set halfway and the crossover at about 70 hz.. I also have some Kappa 12's in my Camaro... go for them if you can.

Easy, cheap price, great quality

I bought this box for some Rockford Fosgate P1's and I couldn't be happier. The box is solid and produces some really good sound in my Audi.

Good quality

I was very surprised with the quality of this box. It was well made for it being a prefab box. The polyfil definitely gives the bass a deeper sound.

Excellent!

I bought this for my husband for his birthday and he loves it!

title

Great box well made great value enough said ten word review

Infinity Reference 1262W

I have two of these speakers and they do the job just fine. They are not the hardest hitting subs but they are not that poor quality neither.

Great subwoofer at a great price.

My goal was to find about a 300-500 watt RMS (DVC @ 4 ohms/coil) 12" subwoofer that would be somewhere between $50-$100. After extensive research on Sonic's awesome site, I chose this model over the similar Alpine, Pioneer and Kicker models.

Pioneer TS-W310D4
Alpine SWS-12D4

The Infinity was less than $60 to my door, looks great installed in my custom ported MDF/fiber box and hits really solid. If I had it to do again, I might have built a sealed box for tighter bass and less space. It still sounds great and I have it tuned right around 33Hz.

I would highly recommend this model. If you are on the fence with a 12" sub decision, you won't be disappointed. The magnet on this thing is MASSIVE!

Awesome value.

I recently purchased this sub for my Subaru Outback and have been more than pleased so far. It's in a sealed 1.25cu ft box, fed 500 watts @ 4 ohms. This exactly what I wanted at an amazing price. My goal was for a good sq sub that didn't require loads of power...goal met. If you're looking for a nice affordable sub look no further. Looks awesome, sounds terrific and doesn't break the bank.

Pros:
Killer price
Amazing sound quality in the recommended sealed box
Looks good

Cons:
Can't think of any off hand.

Infinity Sub

this is a great product sounds very clear I love them

great value

It's pretty good sub for that price hits hard enough for me loving this sub.

Amazing

I bought an old set of infinitys in a box and they were a few years old, those blew within a year. I then purchased 2 Infinity 1262Ws and they've been hitting hard and proud for the past year!

P Dubb

I was very pleased Sonic's as always. The sub itself is a pretty good sub for the money I probably will upgrade to a JL soon though. The 1262 does give the low bass I was looking for.

Sub box

Good product I would recommend this sub box to anyone that is looking for a cheap n quality enclosed

Quality & Affordability

I purchased 3 of these same speakers to go into 2004 Scion XB I had two 10's but the combination of amp & enclosures was eating my subs up, within 1yr 3 different sets of brand new subs fried. I researched & found that Infinity is made by Harmon Kardon super awesome brand, they also make JBL & a few others but anyway these subs hit hard they are installed in single chamber ported enclosure 3/4 MDF the amp right now is a 1600 watt UL8200 i think that's the model # but not sure it's called Ultra Linear, very satisfied with the bass ohh they are wired to the amp @ 1 ohm but not stable as the amp is heating up & shuts down during the hot day here, was thinking of getting a fan on it but i rather just increase the wattage, as the three subs total 900 watts rms & 3600 Watts combined they are begging for more power. Definitely recommend these subs & Sonic is the best deal around, top of my favorites list.

Good quality for the price

I have 2 12 pioneer ts-a30s4 and it's working great inside this box

good value

I bought this to put some ID Max's in for my daily. Build quality is good and the price was right. The box was good enough for me to buy another for some first gen JL Audio 12W3's that I was selling.

By Anonymous on July 30, 2018 Verified purchase

loving my subs :)

I found these on a special for 106 bucks have to say that I am extremely satisfied with them so far... I am a newbie when it comes to this and have them wired to 1 ohm's on a massive n3... At least 5 different people have asked me what kind of speakers do I have.. :) one happy customer thanks sonic electronix

Nice sub for the $$

I have a single 10" in one vehicle and a single 12" in another. Great value, great sub.

Solid Construction

I ordered this box for a pair of AudioFrog gb12d4-12, the box came with a couple of nicks from shipping. And didn't have the poly fill. Customer service was on point.

Good solid box

Its a great box... small compact and puts out great sound...A+ on this. Carpet matched my existing carpet turned out pretty great im happy with it :)

awesome

Its perfect for the price. I recomend it to all my friends

Love Them

They have deep sounded bass, makes the whole inside of the vibrate, I feel and hear the bass like bass suppose to be heard and felt. You cannot go wrong with the subs.....I have a pair in my car and a pair in my truck....

great product

Comes with literally everything you'd need, fits perfectly in my 2014 dodge charger rt. Only think I had to buy in addition was a gauge to be able to lower the volume on the bass. Other then that I love it!

nice

bought 2 of these and got em on a 2600w bamf mono block amp at 1 ohm.

these things rock

Personally I love Infinity (Infinity speakers) and here in AZ is everyone has Pioneer Kicker and people just dont see past that.
I decided on getting Infinity since their so wonderful with speakers, heck why not try the subs. So I did by far since I had them their awesome.
They pound very hard and clear... yet its not a Kicker and will not pound extremely hard either and take the good music out of it.
Even though I love bass =)
They did a great job on these cant wait for the next version...

P.S. I have two of these in a ported box in my Saturn sc2 =)

Great value

Worked out great for me. Will be ordering a second

The item did not live up to my expectation because it arrived empty and damaged.
But for the price its a pretty durable box.

great value

These subs have the best sound and low notes but they don't get unbearably loud

Great value box

Budget-friendly box great build quality has 2 12 at 600 RMS power the woofer box holds the pressure would recommend this box.

By JORGE on July 14, 2020 Verified purchase

Infinity 12

Great subwoofer for the price. When this woofer is placed in the proper enclosure it simply will move you. The range is balanced nicely. Extremely efficient from my small amp of only 150watts/RMS

Fantastic Sub Box

A very well-built and nicely carpeted sub box, that looks great, and should prove to be very durable, as it is constructed with 3/4" MDF instead of thinner material of many other boxes costing more than this.

The black carpet makes more of an impact than the typical gray carpet, and the 5-way binding posts are much higher quality than the typical plastic spring connections normally found on sub boxes.

Very happy with this purchase, and would absolutely consider another should it fit my needs of enclosure volume. (It's not worth the extra time/effort to make a custom box, when this does the job just as well, and comes pre-lined with poly-filled and pre-carpeted)

Love this box worth every penny really solid box everyone should buy it

Great Budget Box!!

Ordered my box and had it at my front door in 2 days! Great box. Its very well built and pure mdf and thick mdf wood. Nice carpeting. Only down fall i see is there was no poly fill and terminals are on sides instead of rear. I thought it was suppose to be this one pictured and both are the same numbers but different box but i am still very very pleased!

By Norman on November 29, 2017 Verified purchase

Sturdy enclosure

This is a very well constructed box, well sealed and solid. However, mine arrived new in the box and every corner had the carpet worn off and bare wood showing. Also, mine was not lined with poly-fil and the terminal cups were on the sides rather than in the back as it appears in photos- no biggy but that did influence my decision as my install would have been a little "cleaner". All in all it sounds great and seems extremely durable.

By ron on August 20, 2017 Verified purchase

Awesome with my dual JL 12w6v2's

Purchased because I needed a new box for my JL Audio W6v2's. Sounds great! Great solid construction, nice that it's already lined with polyfill, no air leaks and the black carpet looks great. Can't beat it for the price and sound quality with my subs in it is excellent. Guess it would be nice if the terminals were pre-wired but I soldered my own wires in. Love it, would buy again Box fits perfect in my '13 Accord trunk

By Jason on March 8, 2016 Verified purchase

great box

Perfect box just what I was looking for. Fast shipping

not magic but helps

I run 200W to a jl 10w0v2 sub rated at 150W in .7 cu. ft box- as recommended by manuf. I get good hard bass. But after testing a few tracks I came upon some punchy bass on R&B and reggae. I experimented with polyfill and wound up using 1/2 lb, fluffed it up and the bass is much better, richer if u will, and no punchiness. This "smoothed" it out, for lack of a better term. I did not hear any increase in sound just better bass, nothing magical. I compared the 60-100hz sweep and noted no difference. But it helps. I do hear that polyfill works wonders for mid bass drivers but for subs all I can attest to is smoother bass tones on hard notes.

Great value

Great box for the price I have two 12" pioneer champion series 1400 watts speakers in this enclosure and they sound great thanks sonic for another great purchase.

Oh BTW I got the amp from you guys too but I don't want to say because I don't want them to disappear they are a hidden gem and way to cheap for what your asking and I want to do a hole package of everything I have now x2!

good budget subs

For as cheap as they are they perform well the sound quality is good and when I feel like beating on them hard they take it like a champ the only things I wish infinity would change is a little bit higher roll surrounds on the subs and the connections to the sub they still use spade connections and they dont come with the needed female spade connectors so I just soldered my wires on

Nice entry value sub component

I first bought pre-fab box by other brand and wasn't satisfied with it. As an entry level budget sub, this speaker rocks with all types of music. I have kept it in a sealed 1.25 sqft box and feeding it with 350 RMS at 2 ohm and it handles it very well. You will definitely love to see excursion since the shining look of the sub. I am also planning to built a vented box for this and will change my review once I'm done with it. The only complain I would have for this sub have small connectors and it makes it very difficult to wire the connection.

Very decent quality subwoofer.

This subwoofer is the perfect beginner buy. It is a very musical subwoofer. This speaker is of a fairly decent build quality. It is not designed for sound pressure level competitions... It is a really sensitive subwoofer. You can get away with lower wattage amps. It is very functional piece for any system. It requires very little box space and is very well endowed on producing the lower hz range. I highly recommend this subwoofer.

hard bass

I would recommend these. I had the previous models in my pt cruiser and they hit so hard i would compare to kicker for a lower rms rating. They had hard hitting bass. I would go sealed on these they sound a little distorted in vented or ported but do hit a little harder.

It is helpful for small enclosures but it is not for ported ones. It gives a bit more power and a cleaner bass even in a ported box. It is not a surprising but its worthed if you want cheaper, better sound.

Very well built box!

Nicely built and good for breaking in any subwoofers. Highly recommended if you like that nice clear sound that cam hit that tight bass.

Great bang for my buck

I have to LMFAO at all those bad reviews bet they never realized 3 weeks. At lest before you go n turn up amp. Today is Aug 19. 3 weeks ago I bought n installed (DIY). My amp n remote were both turned to 2 gain will EVERYTHING ELSE was set 0. Yes at first could not hear it. But in long run worth it. By 5th day at 2 gain was raddling my mirrors. I only got one these bad boys. Due to out stock. I can't even fathom 2 these. Guys going.BTW I still haven't messed with amp or any settings. Pounder on that for awhile.....

Box

Looks good and easy to install speakers in. Made heavy for durability

excellent value!

I have 2 of these in a sealed, polyfilled box with 1.3 cu ft per chamber. They are each receiving 375wrms. They make my rear view mirror shake and flex my trunk spoiler. These are very efficient speakers and make good use of the power given to them. My own complaint is the absence of spring terminals, it made it very hard to run 12ga wire.

Subwoofer box

It looks really sealed and no air will leak and it looks very durable

Good value

I would reluctantly recommend this box. The one I received was already slightly damaged in the corner with carpet coming away from some of the seams in the corners even though it was brand new from eBay.

This is really great subwoofer

Smooth low frequency, real nice color of sound.
I drive ir with Soundstream 1000W RMS,and use one coil 4 Ohm.
Recomend to want to get quality.

Good enough

The sub installed well, and certainly has a quality feel about it, despite being obviously an entry-level part. This is the sort of duality Infinity is known for -- their products are quite well made, considering their position in the grand scheme of things. While certainly no Focal or Morel or even Kicker, they just work. And at the price points Infinity targets, that's all you can ask for.

great value, great product

i bought 2 of the infinity 1262 w's over a month ago. i have no complaints at all. i have them hooked to a cerwin vega 1500 watt max output monoblock amp and they rock on any type music. everyone who's heard them has really been impressed. i highly recommend them to anyone for the price.

infinity

I have two of these in my eclipse and they sound great. I bridged them with a J(2)360.2 and they sound great. I have to get a new head unit soon since, i am using stock. I can only have these subs turned about the fourth the way up, with the bass on my head unit all the way down. Other wise my deck will skip, I also now need some dynomat for the rattle.

Great Value.

This box is awesome for the Price. A little heavy and you must have enough room. It will fill a trunk or back of a SUV. I have two JL 12's ,which makes this a combination that beats. Low, long, stretched about bass that lets the neighbor's; who live a mile away, know you're coming.

Really nice box

I put 2 mtx sub and the bass is really deep,the best, the price is really good.

By Mag80 on November 6, 2016 Verified purchase

Good for the price.

This is an all-around good sub. You won't be disappointed unless you're looking for some kind of over-whelming spl. These will produce clean, accurate bass in a sealed enclosure. I have two of these in a sealed box powered by a kappa-one mono block crossed between 80hz and 20hz, an Infinity 8 inch sub in a sealed box being powered by the subwoofer channel on my kappa-five amplifier crossed between 50hz and 120hz, and I have Infinity 5.25 Reference components and Kappa 6x9s being powered by the other 4 channels. It's a pretty tight and accurate sounding setup with great sound-stage and pretty good separation, for the price. I'd recommend this sub to anyone with reasonable expectations.

GREAT SUB BOX

SLAMS THE BASS FOR 2 12" SUBS HARD AND GREAT. WELL WORTH THE MONEY AND THE QUALITY THAT ITS MADE FROM WOULD BUY AGAIN FOR DIFFERENT CARS.

Made out of high quality mdf nice tight bass highly recommend this box

Dual 12" 3/4 MDF Sealed Subwoofer Enclosure (Belva MDFD12)

Solid product. I wouldn't put a subwoofer heavier than 30-35 lbs each in it thought. It's lined with polyfil so you'll have to cut a small hole where the terminals are but other than that it's a pretty good box for the price.

Infinity 1262w

After reading reviews, listening to couple subs, I deci to try this one!
First time I'm having a sub and amp in my car, absolutely WOW!!!
This s..t is the BOMB!
Love, hoked it up to JL amplifier jx500/1.
And sonic offering very cheap price!
Worth every penny!!!

Dual 12" 3/4 MDF Sealed Subwoofer Enclosure (Belva MDFD12)

Purchased this enclosure for my son's first system in his '16 Cruze. Great alternative to building a custom enclosure. Great match for the ID12s I had leftover from a previous system. Also, as always, Sonic Electronix has the best prices and ships fast.

Best Value!

This was already the best deal for a 3/4" MDF dual enclosure I could find, everything else in this range is 5/8".

For the price I wasn't expecting much.
However When it arrived found it is of good build quality, with decent carpet.

They already lined the inside with polyfil, more added value.

Then to top it off, found it has really nice gold plated screw type wire terminals. Better connection and added peace of mind that connections will not come undone.

This is probably the best deal/value on the internet for a dual 12 enclosure. Probably why it's backordered at time of this review.

Very Happy!

Perfect

Cheap price for top of the line product good bass output

great price awesome sound bad connection

These subs are dvc however they have poor connection options. They use cheap single spade terminals. Dual spades would have made parallel wiring much easier. Or even some push terminals. Akso noticed 1 of the 4 I ordered had a mislaid surround so quality isnt there either..... what happened to infinity ?

Good sub

This sub sounds great. I have one 12 and I'm pushing it with a 250x1 jl mono block class d. I have both voice coils hooked up. I'm actually under powering the sub and it still rocks when I can afford a bigger amp I'm buying another. Would highly recommend for heavy metal listeners.

yea, it's foam

as promised white fluffy stuff. exact same poly-fill found at the hobby store.

Perfect for Small Enclosures

This small addition will add a way better depth to your bass. Awesome!

SICK...

cheapest upgrade u can do to get better sound from your sub, if your box is small and your short on space...

Subwoofer enclosure

Good quality would buy again
Good prices
Always love sonicelectronix

Great Value

This product was very easy to use and it got the job done right. I used it for my 10" subwoofer in a sealed box and it made it hit louder and deeper.

poly-great

i have a 1.7 sealed enclosure and put my cvr in here and i thought it wasnt going to give it bass but i couldnt believe it. great buy!. just be careful on over filling your box they recomend only half of the box is filled with it. and cheap for more bass.!

More Poly Power

Don't like the sound of a sub in a sealed box?
Don't have a lot of room for a box?
This product gives small boxs with any sub a great sound.
Makes a big difference.

polyfill fiber

truthfully i didnt compare the sound of the bass with or without the polyfill, i just read up on what its supposed to do and it supposed to make the box think its bigger than it really is so im just guessing it works and also for $3.99 it was worth it i only used abouthalf the bag in about a 1 cubic volume box in my single cab dakota so u can do a very large box with this bag it goes a long way and if it does what people say tis well worth it expecially when you have limeted space like i did.

Works great

I bought some, I tried it, it works great; I would recommend this to anyone that wants to use a smaller enclosure than is recommended by the manufacturer for the sub or just improve quality of the sound to reduce the distortion a little bit by adding a little bit, but be careful if you surround the sub to closely it may overheat and burn up, but it really does work I use it all the time

Great sound at a great value

Infinity has always been a great sounding product. When I found the Reference sub under $75 I was excited! After installing it and breaking it in it is sounding great as I imagined it would.

Very nice sub and beats all other budget subs out there for sound quality.

Subwoofers

I love these speakers great sound and able to handle a lot of power

This stuff is phenominal!

Stuffed my 10" one cubic foot box with about 2/3 of the package (16 ounces) and am absolutely amazed!! Would highly recommend as a quick, cheap, and easy way to increase the size of you box as well as the clarity of bass.

lol good for cheap boom

I got this for my alpine type r because I had it a sealed and I wanted more boom, for $4 this amazing, the amount you get is bigger than a pillow and it goes a long way, buy it!!!!!

Excellent Product

I bought a bag of this stuff and put in 10 inch enclosure. It made a big improvement, It hit harder than before.

.WOW...

THIS PRODUCT IS THE CHEAPEST WAY TO ADD POWER TO YOUR SOUND SYSTEM ITS WORKS GREAT IF YOU WANNA ADD SOME EXTRA POWER TO YOUR SUBS POLY FIL IS THE WAY TO GO...

I couldn't believe it.

Me and my friends were kidding around on this web site to see what cheap things we could do to make my friends subs hit harder. We find this product and start laughing but we decided it was cheap so it was worth a try. He has oversize subs in these small boxes and we start putting it in and when we turn on the system, THEY HIT HARDER THAN EVER! Worth every penny.

poly fill

It helps a bunch making the sub think its in a bigger sub box and helps the sound....

Good Investment

I had some of this from my previous sub enclosure. At first I installed my new subs without this, but once I put this in the box I got tighter, louder bass. It is definitely worth buying.

works great!

It's awesome and helps give a more "full" sound to a smaller sealed box, so if your short on cash and want more sound this is definitely a way to go. But, as someone stated earlier make sure to be careful when placing it in the box and not to "over stuff" so that your subs won't over heat and end up costing you more money.

Good Stuff

i have this in a single 10" enclosure and it hits harder than i thought...this stuff is great

Better sounds for under $5 in my box.

I have a single DUB 12' sub in my truck and it sounds great. Upon putting a 20 oz bag of Poly Fil in it it instantly made an incredible difference. It sounds stiffer almost like the bass dosn't sounds nearly as distorted. Great difference in sound with a great price. The more fill the better. Start with the little things when trying to improve your system the in-expensive way.

infinity reference 1262w

the subwoofers are some of the best I have every had. They have great response and sound amazing. I would highly recommend these and this company. Great customer service and I will be buying from them again

Poly-Fil

This product is a good price and does the trick. Dont let the pic fool you because a LOT comes in one pack.

Thrifty Buy

Hard pressed to find a better deal, at the mfg and vendor level.

Great to use

Bought this for a small sealed box I had and glued it to the walls. It's really easy to work with and you get a lot.

Does its job for a while

I have gone through two of these. It worked great as Long as I didn't drive for longer than an hour and a half, because if I did they basically caught on fire. Both times with my bass low cause I know I'm going on a long drive, that nice smell of burning plastic came up, and the bass would completely shut off. The red light for protection indicated it's over heating, which is fine, I just think this is more of a speaker amp than a sub amp. Just so you know I have two reference 1262 Infiniti subs and this was the recommended amp in the package deal.

WOW OMG This amp is a MOSTER!

I know that this is one of the best amps you can buy period hands down! Omg this RE Audio XT-800.2V3 hits my Cerwin Vega 12s so hard and clean bass. I'm just so amazed at this small amp but mean as hell with the power it puts out. The place that hooked it up they were stunned at it's power that it was putting out. If you are looking for some big power to run some 12s, any 12s, then this is the amp to go with!!

Awesome Stuff

Added 1 bag to each one of my sub boxes for my Audiobahn 12's and 15 SE. This stuff really works makes bass sound clearer and tighted. Greatly improves sound quality. Need ato buy if you own any subs.

polly-fill

ok, this is worth every penny, i bought a bag of this stuff at wal-mart for 4 bucks, expecting nothing out of it, but it definetly makes a different in the small box i have in my single cab s10! it added a much deeper and cleaner bass than before. Worth every penny! It is one of the cheapest ways to improve your bass!

Best bang for your buck

I bought 4 of these installed them in my trunk to replace a re18. Better spl and sq for the same space at half the cost. Equivalent to jl w1 for sure in sp and output. Terminals a little cheap but at this price somethin has to be. Highly recommend

Just follow the instructions and you are good.

Very nice product for getting more bass out of some smaller boxes. I used this in a 1.4cuft enclosure for a kicker sub, and affixed it with super 77 and it stays fine and does help the bass out a little by giving it more time for the air to reach the box. This would also be very useful for making your own home theater speakers and filling the small spaces you have to work with. Just dont overstuff it, and follow the instructions you get.

Infinity1262w

Sub is one of a kind solid build and hits HARD (custom box) built to spec
Sub hits high and low notes I would recommend this sub to anyone who is looking for great sound and manny years of use

why not get some?

I got this for my sealed box I made. Helps trick the sub into "thinking" the box is larger than it is. Works as expected.

Severely Underated

A few yrs back I owned an 8" infinity sub and it rocked. With that experience in mind I purchased 2-12" subs for my fox body project. This was not a disappointment. The two 12's far exceed my expectations and I only wish the made 15's or 18's. The bass is crisp and hits the lows with ease. At high volume they continue to perform with precision.

awesome sub at a great price.

I have this sub powered by a Rockford Fosgate 500 watts RMS amp using a ported sub box. The sub is super loud given its power rating. The whole car shakes. Infinity makes great products.

Great Value

Really good value. Works well. Have absolutely nothing bad to say about it. Would buy again.

infinity rocks

I had the older model subs a few years back in my 04 PT Cruiser and they bumped really really hard it would make my chest hurt if i turned it up half way and my vision got blurry. Infinity makes some good stuff i deff recommend these if your want large clean low and high bass so get em great price. Sonic rocks! This is the only place i'll buy from ever again. i recommend the Kenwoods also. any of them sounds really clean.

Great all around sub

The performance of this sub is absolutely great. Perfect for people that listen to all types of music. The bass that comes from this is powerful even at low power due to it's efficiency. Tight clean bass that will satisfy anyone in this price range.

Good Product

This wiring kit was well worth the money. It came with pre crimped power and ground wires so that was nice. My only complaint is that the wire gauge seemed a bit exaggerated but thats almost to be expected with cheaper wiring kits. Overall it was a good value for the price.

Nice kit

This is a pretty nice kit. The price is unbeatable.

pros
-soft touch power/ground/speaker/rca wires. its the first kit i had with soft touch insulation and i love it! doesn't tear up your hands.
-very flexible
-great rcas
-already crimped ring terminals
-ofc copper!!!!!

cons
-need 4 gauge spade terminals
-more like 6 gauge but still is good for the price

slammin subs

You literally cant beat this deal, i bought this package for my 2001 pontiac grand prix and i get roof flex and my car litteraly bounces when i turn the subs up. This is a great package for a low price, Sonic always has all the right stuff you need to satisfy your wants.

not bad not bad

For the price it wasnt bad i mean considering you will spend twice as much if not 3xs as much if you go to to another retailer. The price just cant be beat. No, this is not as thick as it should be its more like a 6ga. I received my spliters that i also ordered from Sonic along with the amp wiring kit and there were alot nicer than ecpected MA audio brand. So if your in the market definitely take a look at their selection.

Big bang for the buck

I would strongly reccomend this for the money and if you want some slammin subs. I just bought these and if you bridge them at 4ohms it's rediculous, the amount of bass is tremendous. Only way it would be better is if it was a ported box instead or sealed. With these subs i get roof flex and my mirror has officialy rattled off.

Nice!

I would recommend this kit. The color is nice and the fabric used well done. To top it off it was a great buy for a four gauge kit. Next is the 0 gauge.

Awesome product

This product has stand a test of time since I bought on eBay some years ago

Best pricesi found!

AlwYs wanted to build floor speakers with the kappa's but these were subs. Not just regular woofers. If in any way they would have worked in floor speakers and not just sub cabinets nodoubt I would have used these pieces of art.unbelievable price from these outstanding people. Anyone considering subs or a car system. These are most definitely the guys I am going to be coming back to. Nice,knowledgeable and so very easy to deal with. Unsurpassed courtesy and excellence.

I enclosed it in a sealed box, and it sounds great. Incredible perhaps for the money. I listen to everything from rock to blue grass, and it's response to kick drums and a standing bass is superb.

Solid bass with a great appearance for showcasing. High db count makes it very easy to push even with a not so powerful amp.

Elite Audio 4 Gauge Kit

I bought this wiring kit because it was cheap. I knew it would get the job done... However it was a pain keeping the battery cable to stay in the fuse and the remote wire crimped properly. Everything you need is here... just a little frustrating.

The missing piece!

I'm a musician and was looking to upgrade my car audio to sound more like the stage when I play live music. This sub is very musical and rich at reinforcing the low end in my music. I have it in a sealed 1.25cuft box behind the seat in my Accord. Powering it with 300W RMS I'm very happy! It's not breaking windshields or rattleing my car apart, and that's great! At this price point i should've done this much sooner!

Infinity 12" subs

The best replacement sub's I purchased. I honestly did not think it would handle my set up, but its quality and yet affordable.

Great woofers!

I bought two of these and paired them with a Alpine 500 watt Class D Mono amp in a sealed dual enclosure. I know that's not a lot of power for these woofers, but at 500 watts RMS these things hit SO hard. Had some kenwoods before on the same amp and these are so much louder and cleaner. Great value for great subs. I can't imagine having them on a larger wattage, they're so loud I have to turn it down sometimes! The are slightly complicated to wire.

Great value for the money.

I've got a pair of these running off a jl 500/1 in the recommended size sealed box. Not the most insane twelves I've ever heard but for the price you can't go wrong. Had to get another amp for my front speakers just so I could hear them properly. Lets see how they hold up.

Good Subs

Good subs for the price. Good sensitivity too making them more efficient then most subwoofers in that price range.
