OK wire if you like red wire

I received this wire because when I bought my Image Dynamics speakers from Sonic the description said it included speaker wire in the box, but when I received them there was none. I called Sonic and they sent this wire to make up for the error. I later called Image Dynamics and found out that they no longer include speaker wire with their speakers so Sonic if you are reading this you can update your description and pictures on the ID speakers to NOT show speaker wire. For the record I bought the Image Dynamics CTX65cs and the CTX4 speaker sets. Great speakers by the way. Thanks Sonic for all your great products and sound advice, no pun intended:)

Quality Product

Works very well with my Rockford Fosgate sub system in my car.

good deal!

Pretty decent value for the price. Worked out great, thanks.

Usable

The wiring has done me right so far but the only thing I don't like is the speaker wires. You have to carefully split it so the wire doesn't show. Other than that minor thing everything was great and a great value!

price is right

the price is right for this setup. the ground wire and the power wire are to big for my amp but i made them fit. better to have to much than not enough so if i upgrade to a larger amp it will be fine.

nice sound

very good product at a pretty good price lowest i could find on net and sounds good

Accessories for product

Just what I needed and made installation so much easier. Thanks

works great

Hooked it up with an re audio srx 12 and it sounds great very very happy.

decent box

i bought this box for the newest alpine type r.... lets say it sounded decent but not good enough for me, i have had many sound systems and this didnt sound so good with the type r..... if your decide to get a type r id go with a 3.0 cu ft box tuned 32-38hrtz for the best deep loud sound quality

awesome products

I run 2 12inch audiobahn exursions on this amp and it pushes them very well. The size is perfect not to big and fits right unerneath the seat or small space. The best part is it stays pretty cool even after running most the day.

Great Solid Box

This box is built very well. It's perfectly tuned for the Alpine SWR-1243D Type-R that I also got from Sonic Electronix. The SPL of this combo is ridiculous in the trunk of my '09 Civic Si Sedan, and it leaves more than 3/4" of my trunk space left for other junk. Definitely recommend. With a set of banana plugs also ordered, I still only spent less than $225 which includes the price of shipping for these three items. Speaking of which, I ordered in the early hours of Tuesday (switching over from Monday) and I got the these three items delivered to my door by 11AM Wednesday! There's no way you can find a better deal than that! Now all I need for this combo is some serious Dynamat to keep everything from rattling apart.

Great Box!

This is a nice box for the price. I normally build my own boxes but I didn't have much extra time and it is too cold out to build one anyways, so I bought this one and I'm sure glad I did. Realistically to buy a sheet of MDF, spray adhesive, bottle of wood glue, nails, and carpet costs about the same as this box and it is already made. Sure it is prefab, but its a very good prefab enclosure. This is real 3/4 inch mdf and the port is tuned pretty low too. I would guess like 34-36 Hz or so. Very solid construction and rounded off port on the inside. Carpet looks great. Terminals are nice too, although they are plastic fasteners, they will hold up just fine. I have a Phoenix Gold rsdc in this box and it slams! I can feel the bass pounding my chest. If you want a nice loud box, this is the box you want. Exceeded my expectations by far!

Not correct box volume

The box is advertised to have 1.8 cubic feet of volume. It's not, the actual volume when taking into the account of the wood thickness and the ports is 1.3 cubic foot. Plus when you add a sub in it that will also take up some volume so you can count on 1.1-1.25 cubic feet with a sub mounted. The 1.8 cubic foot might be true if their talking about total volume of the outside but that is compleatly irrelevant. The only volume that is important is the inside of the box. And yes the difference between 1.8 and 1.3 is a lot and will make a difference

Belva

I have 2 of these in my car but they do the job with Type-R's no complaints

Bela Sub Box 1st 12 box

The box is built great, sturdy. I didn't pay attention to the overall dimensions the box is bigger than your average 12" box.
So if your looking to put this box in your car make sure you pay attention to the dimensions. But if your building a subwoofer for home or small club this box will do the job.

good wires

I like the wire kit I got with my amp it seems to be holding up goo it handles the power of the amp I got but I would of gave it 5 stars all the way around but I wold of like the ground at less 2 more feet for good use but over all its a nice kit

Good stuff

Great product last a long time good value for the money.

awesome subwoofer box

This subwoofer box is great and produces a lot of loud bass. However it is huge so make sure you have enough room.

A+ product

Fast Fast shipping. For all you guys that are looking for a clean box with great value and durability this it. I'm using it to support my 12" Olympus Series Dual 2 ohms Subwoofer (OLM-1612). Buy it !!!!!!!

Sick box.

It's pretty massive. Carpet matched my trunk which is a win. Screw terminals are not the best but they work.

Cable

Good product fast shipping awsome seller... keep up the good work.....

Use to purchase this all the time

Belva brand is good affordable material when starting out but through out time cca corrodes if you have the money buy ofc cable

great box

I bought this belva 12in box last month and put a 12 in kicker comp r in it whick I'm putting 800 watts rms to it and it sounds great. This box is also listed at a great price.

well built

this is a very solid, well built box. the box is sealed well at all seams also and made of good quality mdf. I have a kicker cvr in it and it sounds great. great choice for a single ported enclosure. can\'t go wrong. by the way, i think it has great binding posts. good value, it won\'t disappoint.

Perfect kit

Comes with everything you need. Works good with my 800w system

By Chad on May 14, 2020 Verified purchase

Nice product

This box is a very nice box especially for the money. Gives a crisp clean sound and doesnt matter what type of music you are listening to.

Great box

I put an Audiobahn Alum12X in it with a 200 watt RMS amp. I had to widen the hole a little to get it to fit. It is nice and loud. I put it in the back of my Honda Element so the port fires under the rear seat toward the driver seat. For the cost it cant be beat. It would have taken me hours to put one together. What a time saver. This is the first box I have ever purchased. I usually just make my own.

decent sub box

Bought this box for my son and put a sony 12 and visonic amp and it hits pretty hard and very loud but not as tight as the sealed box he had so he loves it because he's a teenager !

Solid well built box.

This box is great. ! I have a Power Acoustik GW3-12 in this box and it really pushes some air! All my mirrors are blurry while im driving nice clean bass

great

hooked it up to re audio srx 12 and it sounds great

Sounds great

This box sounds great with my alpine 12. The terminals were easy and the box is put together well.

Good extra fine wire

This is excellent speaker wire. One wire has round insulation while the other has square insulation making it easy to identify hot and grounds. My only installation problem was I didn't order enough. I needed a quantity of 2 just to wire a single cab pickup.

Good Box for Cheap

I needed a box for a C2 Audio Threatcon 4 subwoofer. C2 cuggests a box near 2 cubic feet tuned to 35 hz. This one is tuned to 36 as a I recall so it's pretty close. It's nicely constructed. Wish that it were slanted so that I could put it up against the rear seat of my car and that it were tuned a bit lower. For 35 bucks I couldn't build it for less.

great buy

my brother bought this for his kenwood 12. it sounds like he has 2 12s. the crazy thing is he is only pushin 220watts rms. box makes all the sound. get this if you need a great box

Great

I bought this box for my Rockford P3. The box takes up half of my trunk but it slams my sub. You can't find a better deal on a ported box like this anywhere

works great

this box works and sounds great if your sub calls for the air space buy it

Belva sub box

I have owned this subwoofer box for 30 days now and it sounds great and looks great. The porting on the box makes it sound even better. And is the best box for the money

Outstanding quality & Price

Would recommend, sturdy construction with insulation.
Improved bass quality, w/new box I could hear bass notes that were missing before.

Bad.

I bought this box a while back and one of the speaker wire terminals is loose causing the connection to be weak.. its been loose since I got it but it just recently started causing problems.

pleased

I bought this to go with my orion xtr pro. it makes the deeps better mids louder and highs annoying. Make sure if you buy this product to tighten the connectors a little more. i put my system together but damn near broke one of the connectors when tightening by hand. Other than that i am very pleased with this product. Sonic Electronix never fails me! I recieved it in three days from KY to WI!

1SV12

I bought this box for an Alpine Type R 12. I usually build all my own ported boxes but I decided to save some time and buy this one. The box is built from quality 3/4" MDF, the carpet looks great, and the seams are well caulked. What you really should know when buying this box, it is around 1.5 cubic feet net, and tuned to around 35hz. A little small for most 12's in vented applications, but the 35hz tuning was a pleasant surprise. Most prefab boxes I've seen are tuned >40hz and can't quite hit the low notes. Overall, definitely a great value and a decent design.

Not to bad but could be bigger

Got this box to house a American bass xfl 12". I needed a bigger box but I have a small trunk so my options are limited. my 12" beats in this box just not at full potential. good box for pre-fab

great box

This box is great and you wont find such a nice one at this price anywhere.

single 12 inch vent ported box

Bought this box a while back and must say for the price its a great box. Ive looked at other higher end box's and they are way over priced. Good construction and seems sturdy. I would recommend this box to anyone who wants a single sub system.

works well

works well with my alpine 12". installed the sub into it myself, very easy. good value. go sonic!

great box great price

u will never find a better ported box for this cheap. it is very well built. sadly it is currently serving as a nightstand in my bedroom due to the sub no longer living there lol

Great Speaker Box

Makes a big difference in the bass. This box is good for a smaller type of trunk.

Awesome box

Looks attractive, feels sturdy, wasnt expensive. Perfect for my memphis 12. I actually ended up with the exact box except black.. so i assume the picture is wrong, although i'd rather a black box anyway.

Good wire

This wire is great speaker wire. I like the way it looks and works great.

great box for the price

It sounds great. and looks nice. fits well in my trunk also

Worked well

Was used for mtx 9512-44 worked well for what I needed it for...

Awesome

Great sub box, looks good. Its heavy, heavier than i expected. Lined with the poly fiber stuff as well

Strong Box !!!

A well made , strong, & nice looking box .Being glued then screwed is the only way for a sub box, to be made , with the vibbrations it must enduere ,this one pass the test .I have recomended them .

not the best for a type r

its pretty loud but tends to sound kind of sloppy at some notes. if your new in the audio game i would get it but i wouldnt recommend it. if you want to save a little money id go with a sealed 1.0. on the other hand if you want crazy loudness id go with a building your own ported box or you can find a good prefab tuned at 32-38 hz. but im happy with it but soon to change box.

box

this is a great box, great build quality. great port flow and absolutely no port noise. great box

Great buy!

Matched the air space to my boston g2 12'' sub have no complaints at all
sturdy, clean !

Great value

Ive had this box for a good 6 months and havent had any problems. Very durable and built right. Im running an RE 12 and an RE amp in a tahoe and this thing slams! It would be hard to build one for this price. Only complaint i have is that it stinks like they heat treated the mdf or something. My truck smelled like a forest fire for a good month or two.

Sub Box

Great box! Excellent quality, especially for the price. Have had it for 6 months now and it looks like new. Very impressed for how cheap the price was!

Great Box

The works perfect. The box is more durable than i thought it was going to be. Just the right size that i needed. I even put some poly-fil inside to enhance the sound of the subwoofer. Great price for a great box!!

Great so far!

Bought it six months ago to house an Adire Brahma 12" (old-school). I needed 3/4" MDF and around 2sq.ft., ported... Even with shipping it was about half the price of buying a similar box locally, because all my local shops are rip-offs...Sonic can't be beat for price!

So far, everything is great! Only thing that's failing is the window trim on my Pathfinder. X)

One hell of an upgrade

went from sealed .8 cubic foot box to this ported box for more volume. the difference was night and day. i have scaled back the gain on my amp and dropped the sub volume to 0 on my deck, and this box still provides so much volume i'm afraid the back glass will fall out. simply unbelievable. fyi, alpine type x and hifonics bxi1606d, 1100w rms @ 2 ohm.

THE BEST

This box is the best if you want a ported box. It just has everything you need for a well cheap price but the box is just amazing. I put my kicker cvr 12 and that thing bumps, am definitely buying another of the same box for my other kicker.

Okay enclosure

I bought this box because it was a lot bigger than the previous box I was using. I have a Pioneer Premier TSW3001-D2 in this box and it still needs more than 1.8 cu ft to show its true potential. Overall its a good box and it does have good sound quality, but I am not hitting any of those low notes with it that I really want.

Excellent value

The speaker wire is a good price for the length and gauge.

Great box for a prefab

I have a RE Audio SXX 10” in it. Sounds great in the box tight and clear. Bo is tuned to 36hz. Great box.

great box

nice well built. only thing it lacks is being pre wired. so you might have to spend a few bucks on connectors. but it is nice. buy it

im running a dvc 12inch pioneer champion series off a fli acid amp its 600watt rms 2ohm mono... bumps

Great value!

This is a great well built box. I have an RE12" sub in it and it produces the sound that I wanted. Great box recomend to all!

nice box for good price

product is durable, produces good sound and is a very good deal

great box!

When I got the box, it was broken at the face plate by the port. It was in the bottom corner. It wasn't too bad so I decided to drop the sub in anyways.
I have an nvx sub in it and it sounds really good. The lows are deep.
Overall it's a good quality box and sounds great

good box

This box does what it says. Make sure to use the right screws as this is soft wood and will strip out.

Solid box for the price!

This is a good solid box for its value, very study and looks decently sharp. obviously there are better boxes out there, but for this price you cant as for much more. i'd recommend it to anyone trying to build a system with out big spending. great product, thanks to sonic for low prices and super fast shipping as always

Good deal.

I purchased this for the value. Everything you need for a simple single amp install in one package. Good quality with good value, thanks.

Great Value Kit!

I would highly recommend this package to anyone looking to do a cheap install, i have friends who got these before and its nice, simple and cheap!
Never had any issues, great value!

By Craig on October 15, 2016 Verified purchase

Ok. not the best kit.

The eyelet connectors are flimsy and the speaker wire is hard to separate. When it does it exposes some of the copper. Otherwise the kit is ok.

By Lloyd on December 10, 2015 Verified purchase

Ok value

Good product , but not enough speaker wire to wire two front door speakers in a scion xb. I guess it would have been enough if I had run one of them with the power wire instead of running on the other side of car, but everybody knows that's a bad idea due to engine noise. You would think they would take that into consideration. Also not a big fan of the square and round speaker wire very hard to separate and strip without exposing bare wire.

Great value

Does the job does what it needs to do. It was packaged nicely.

You get what you pay for....

Bought this kit for my 650 watt rms amp. Not true awg 4 guage, but close.jacket is pretty thick.all wires flexible. Reached under the back seat of my 2008 silverado crew cab. But not a whole lot of slack if your going to a trunk. Fuse is ok... ive seen better and worse. Bottom line, if your on a budget and running 800 rms or under, this will work fine.

Great wires!!

After reading reviews and most importantly watching the video Sonic posted with this product, I decided to give it a shot for my Cerwin Vega VPAS-12. The wires are exactly as described, true 4 gauge, not all insulation like the other brands. The fuse block is solid and easy to set up. I was worried it may not fit the VPAS connectors since they mention 8 gauge, but it works and it is holding in no problem.

The only thing I did change was the actual battery and ground terminals, they seemed weak, so i chose something stronger and all is well.

Thanks again Sonic!!

Nice enclosure.

Bought this box and put a Pioneer Champion pro series 12" in it. Only pushing about 400 watts to the 600 watt Pioneer, but sounds nice and clean. Hits the low notes well. I really like the durable gray carpet, (doesn't tear and get dirty as fast as other black boxes I've had in the past). Box is well built and I like that it has pre-filled walls inside.

awesome box

I have a cerwin Vega vmax that I've had in a homemade sealed box for years. It sounded great or so I thought. So I bought this box because I wanted my sub to get louder and wow what a difference. I could not believe what it did for my sub. I didn't change a thing but the box and it slams so hard u can feel it in your body. Could not be happier with this box. Appears to be good quality, mine came with a metal belva name badge at top left of box. They even painted the inside of the port black. Long story short lol, get this box.

FORGET THE RE SUBS

I've used this same sub box for 4 different brands of subwoofers and they all fit perfectly. This is a GREAT prefab box UNLESS you're wanting to use an RE sub. I bought this box with the RE Sxx and the basket is bigger than the opening of the box, so it won't work without modifications. And the only reason to buy a prefab box is not having to go through the hassle of making modifications. So it's a GREAT box, will be the best prefab you'll find for this price, just DON'T buy it if you're wanting to use an RE subwoofer.

Nice Box.

Well built box. I like the durable black carpet lining. Holds up well and doesn't tear easily like other boxes I've had. Check how much room you have in your trunk because it has a good amount of cubic space. I still have plenty of room in my 07 Honda Accord. Love that it's pre-filled. Have a pioneer 12" champion series sub inside and pairs up nicely with this box. Sounds clean and the lows hit nice.

By Joey on September 27, 2015 Verified purchase

Great product

This product works great. Sound quality is definitely good, and I would definitely recommend this for anyone who's looking for a ported box.

Love it!

Bought the sub box about a month ago and it was easy to install, no problem with my 12" sub. Looks beautiful and professional and my sub sounds great and non-distorted.

Decent box

Id revomend this box for anyone that doesnt need a custom box

Good price and well made

I was looking to down grade to a single 12” and this box was a perfect purchase for what I needed with still having space in my trunk for other items.

Very nice budget enclosure

Been running an Alpine tye R in a sealed box for a while and have been OK with it. I have tried this 12 in a couple of other prefab vented boxes and sound quality was terrible. One box was similar in size to this but was tuned way too high and was nothing but boom. The other box was much bigger and tuned to around 32 hertz and was a little better but had absolutely no upper bass and an overly pronounced low bass impact.(very uneven response even after much time spent on setting adjustments) With only a day of listening to this particular enclosure, I have to say it's much more musical and really surprised me. It's blending with my components much better and has the advantage over the sealed box of digging into the very low bass with more authority. I'm hesitant at this time to say it's actually sounding "better" than the sealed box but at this price point you can't go wrong here. Construction is good overall and my box had no cosmetic flaws at all. My recommendation is, if you want a relatively smooth sounding vented enclosure that won't break the bank and looks real nice then this one's for you. Really, at this price point it's a steal and I highly recommend.

By jeff on November 16, 2017 Verified purchase

Quality > price, must buy!

I bought this for my nephews new civic. He has a kicker CVX that requires 1.8-2.5 cu ft of airspace. I purchased it through sonixelectronics eBay page for 44 w free shipping. Pairs with the sub and matching 300w kicker amp it produces 42hz of clean clear bass. The beauty of ported boxes is that you can get clean low punchy bass with minimal wattage (assuming you make sure your speaker is wired correctly so the resistance matches what your amp can push efficiently). Look up the wiring diagram for your speaker and amp then match the lowest stable ohm possible. Matching the ohms resistance is more important than just getting the most wattage and your system will last longer and endure less stress. Ok now back to the box. It comes carpeted in either black or dark grey and comes with a nice layer of insulation inside which helps produce the low clear bass and the knock behind it. It also comes with a removable manufacturer tag if you don't like the look. The box has really nice terminals that accept banana plugs which I highly recommend, not only do they look nice they make the connections easier. Overall the quality and value of this box far outweighs the cost. I really couldn't get over how nice it was for the price and when I install systems where only one speaker is involved I am now recommending this box if they do not want or cannot afford a custom box. You won't be disappointed with this box, & for any reason you don't like it send it right back to them.

Good box, was looking for something tuned a little lower.

Well built box for the coin. I did cut out the polyfil just so the port was clear, but left the rest in. It's got a good universal sound and is a lot more pronounced than the sealed box I had before. I have a 12" NVX VCW dual 4 ohm, bridged down to 2 ohm running a Hifonics Brutus 1000.1D
At max I am getting 700 watts RMS, but probably less. The sub is broken in properly and sounds great in the box, but would hit harder with another 300-500 watts RMS. I have my subsonic filter set to about 25HZ. I think the sub plays a little lower than the box is tuned for, not sure, but I think the lows could be better if the box was tuned lower for the particular sub I picked.. NVX tech recommended 2.25 cu. ft. @ 30 HZ. I will be building a new box when I can and tune it closer to 30HZ with a bigger amp. Like I said, this gets me by fine and I have no complaints!

Solid box

The box is solid and good quality plus it came with polyfil. The carpet on the box was peeling around the port though. Wasn't enough to me to send it back but still.

Sounds great

I was skeptical at first for I was going to go with the box made by Rockford for my P3 12'' but decided to go with Belva to save a few extra bucks and man I am happy I did. Its not to big and looks great aswell as sounds amazing for my Rockford P3.
Would recommend to anyone interested in this product!

By Travis on February 24, 2016 Verified purchase

great value

This is an awesome box. I have 2 of them holding my twelves. Very loud deep bass. Would definitely buy again.

Decent budget box

I put a 12" Alpine Type R in this box. The carpet near the port needed a little extra glue to properly hold it down but not a huge problem. The R definitely likes it. Gets nice and loud and the box doesn't have any funny rattles or noises. The tuning is pretty good. Would prefer 34-35hz.

good box for the money

dropped in an old rockford hx2 12con 800w and it booms good after amp and crossover adjustments.

I have had this box for about a month now. I am very pleased with it. I have an Orion XTR Pro 122 in it and it's very low notes. I have no complaints

The best

This boc is the best i have gotten in long time from 100w to 50000w .. This thing does it all..looks size design the best tbing about it is the sounds it put out ..good job

It's a box

works very well with the alpine type-s 12. The only problem I had was the metal plate on the front rattling but it just two screws to remove and the problem was solved

I'm amazed

I purchased this box for my friend. He has a 1st Generation Alpine Type R 12" subwoofer on 300 watts and his system honestly scared me because it was that loud. He seemed very happy when I got this for his birthday, and it makes me happy too. Very fast shipping and easy to install. Loved the cotton inside the box as it helps up the cubic feet inside for the sub to operate in. 5 stars.

Put a 500 watt sub in this box and wow. It sounded so good playing at any volume. The box is sturdy and good quality. The sub did match up with the box. The polyfill inside the box makes a big differance also.If you have a 12 and need this size cu ft air space box this one will not disappoint.

Awesome Prefab Enclosure

This enclosure is made extremely well. It made my NVX VSW124 sound amazing. It looks nice and will turn any subwoofer install into a professional looking setup. I’d buy this or another Belva enclosure and non enclosed subwoofers over a powered or non powered pre-made setup any time. Buy you sub, an amp that meets your subwoofer’s RMS, and the appropriate Belva enclosure, and be amazed. Amazed at not just the sound, but how much you saved over a pre-made setup.

Free shipping, what????

This is a killer buy with free shipping. I used an Infinity 1260W woofer in this and it cranks with only a 200w amp. Place the woofer facing backwards in the trunk and near the back for best bass.

Great value

Works good what I need good price great service great quality

Very good quality sub box

Very good bow made with quality materials. The sound is amazing...

Great box for the price

Great box, sounds good and well built/sturdy. Only negative is that it smells really bad.

Box

The ported box was a good buy. Very convenient with heavy bass.

Solid construction and good sound

Installed a Rockford Fosgate Prime 12" sub-sounds pretty good...Definitely good for someone looking to add some punch to a mild system.

Everything I Needed

Used this kit to run an amp to the trunk of a 2015 Kia Optima. Ended up trimming about 1½ft of excess to help clean up the install. Everything seems to be good quality. Ran the power wire down the driver's side and RCA & amp signal wire down the passenger side to avoid any interference. Plenty of length of everything for a full size sedan.

Great box

I put my P3D412 in this. Had it sealed.

My word yall it sings ported in this little box. I will never go back to sealed. I was a sealed fanboy for 20 years.
The p3 sounds great in this box.

Good kit for the price

The power and ground wire are fine , speaker wires are interesting. One side has square and the other is round which makes it very easy to know what you hooking up to what. Came with everything it was supposed to.

Great promo item

I got this item as a promo for buying my amp. Has everything you need. I would've preferred it to have a red power cable and blue remote wires.

Free amp kit

Normally I use OFC but this kit was free for a starter system and has been running good since install. Wires are nice and flexible, lightweight and pretty well jacketed.

Great box for the price.

This box is perfectly spec’d for a lot of great subs and it’s built very well for the price point. If I need more pre fab boxes, this will be the one

Great subwoofer box, Great box for JL 12W7. 1.8 CU FT, 36 HZ.

Great subwoofer box, Great box for JL 12W7. 1.8 CU FT, 36 HZ. I got this a enexspensive subwoofer enclosure for a JL AUDIO 12W7 sub, until I can build a custom one, it was the exact air space and recomended tuning, it worked out great, Ijust added a baffle ring to get a perfect fit on the sub mounting hole. The carpet could have used better glue, but at $70, it's a amazing deal. And great quality box, I would buy another anyday.

Good build quality and Value

This box chnged the whole tone of my car. I have a kicker compr dual 4 in this box and sounds so much better than a sealed box. I think it's now louder on same power

Sounds Great

The subwoofer sounds great and looks great. I've had the models previous to this sub and loved them.

By Brandon on June 18, 2024 Verified purchase

Beyond impressed!

I have a Rockville W6 12" sub. I had it in a sealed box and it was loud, I have never had a ported/vented box and wanted to see how my sub would sound in it. I cant believe how much louder and clearer my sub is in this box! I would not hesitate to recommend this box to anyone who is looking for great quality and performance! Absolutely amazing!!

The subwoofer sounds great and looks great. One 12" is enough in a sealed NVX box with an NVX NDA11005 @ 2 ohms.
