Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
HF (Hifonics)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
800 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
400 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
Not specified by manufacturer
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
87.25 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
6.5 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Injected poly light rigid
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Rubber
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.25 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.25 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.6 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.0 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
5-5/8"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
10-15/16"
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Keeps blowing me away more and more!

November 6, 2011

This sub just keeps hitting harder and lower! I'm amazed and blown away! I was underwhelmed for a while there because I realized that I actually killed my previous sub by sending a very strong and very clipped signal to it by having the gain set too high for my head unit's preamp voltage. To reach the ~250W RMS the amp is rated for with my head unit, I need the gain knob LESS than half way up. Any more than that and it starts distorting, and this is not because of the sub but because I'M SENDING A CLIPPED SIGNAL FROM MY AMP. I feel like I've officially made that step from n00b to experienced installer. I had read all the instructions and guides before and never understood what they meant by matching the head unit's preamp voltage. Now I do and I know how not to kill a sub (and/or amp, for that matter).

Anyway, I had never broken in a sub and this sub is STILL blowing me away! It's hitting harder and it does better throughout the entire range. The lower notes (centered in the mid to high 30Hz range) I could barely feel at the start are now making the car have a slow, deep vibration when they hit (remember it's a sealed box). Being a 400W sub I feel like playing it full-blast at 250W RMS is good enough as 'breaking it in' and it is just finally beginning to impress me. It's hitting almost as hard as the Memphis sub that was getting a clipped signal with a few extra watts to compensate for my bass-trap trunk (thick leather seats, kills any bass trying to come from right behind you). Right now I'm keeping my rear seat's backrest down so I can feel the full effect of the sub.

I just can't wait to give it 400W. OMG. What a great sub. If 'you get what you pay for' is true 99% of the time, the HFX12D4 is the 1%, by far!

Good entry level sub

December 15, 2014

Good sub for moderate power systems. Doesn't like peak power tho. Went thro 2 of them with 750 watts max. If your going to dump some power into your system (+1000 wats), subs are not the place to save some $$.

I got two of these and they're pretty good for the price. I've had them for over a week now and they do hit pretty hard. I have them hooked up to a cheap nitro amp and it's powering them but for the kind of music I listen to these subs can't really handle it. They're great for country and rock music but not songs with deep low bass.

Ordered to replace a MB Quart. Doesnt hit as hard. Sounds very full. Have it in a 1. Cut ft box it is to small. Think that could be the problem but it sounds good enough. Using Kenwood exalon single channel class D bass amp. @ ~350 watts @ 2 ohms. Could turn the amp louder but my highs are from the Jvc deck 22x4 rms

Most people think I have a much larger sub. Great job Hifonics! If you are on a tight budget, do not hesitate to buy this sub.

I've had these subs two of them hooked up to a crunch 1500 powerzone amp in a sealed box and they bump!! I've had them for two weeks and still working great! I had a previous set of subwoofers that hit great lows and I'd say that these subs don't hit great lows but they hit really crisp mids and highs :) I love them either way at great price I don't mind I'll probably get a third 12 that mainly hits great lows to even out :)

Worth every penny, and then some

March 18, 2014

Right out of the box and into another box, lol.
I have it hooked up to an alpine mrp-m500 amp with the gains corectly set then pulled back a little, as I want to have even amounts of bass in comparison to the other speakers. This sub sounds excellent, I know you get what you pay for but this is too good! The sub hits hard and clean and can handle the s*** I give it. I have the sub wired down to 2 ohms at 500watts, which is the happy max of my amp. It handles the max power without issue.
The only drawback is that poorly affixed cover on the magnet, some frequencies make it vibrate, but it can only be heard when my trunk is open and I have my volume past 70%. Solution? Tape wrap your favorite tape along the gap between the cover and the chassis of the speaker. Viola best speaker ever! You don't get this quality at this price anywhere else.

December 27, 2013

because of the design or the cage. the plastic cage rattles against the metal right below it. at first i had thought i had messed up my friends subs. then i realized because of the design of the cage it made it rattle. its a VERY easy fix. just go to your local hardware store and get some all purpose silicone or caulk and put it right underneath the plastic cage inbetween the plastic and the metal. let it dry. hook up your subs. problem solved! these are great subs. for the price of the subs i think its worth spending an extra 5$ and putting silicone on it.

one of my FAVORITE subs. they hit NICE AND HARD. i would definitely recommend

Not only does it look cool, but it sounds great. Put it in a vented box from Sonic with correct recommended volume spec. I am powering it with an "old school" Hifonics "Odin" amp with 75 watts per channel. It produces "vulgar" bass......For that kind of performance, with relatively little wattage, it is very efficient. It is similar sounding to my Alpine single coil 12 inch. Without a scope, it is hard to tell which has lower frequency response.

Better than previous model

June 7, 2012

I have 2 of the older HFi12D4 in one box and two of the HFX12D4 in another, both in parallel, so they took same exact power and the Hfi burned up at around 250W RMS (1000 divide by 4) while these remained unaffected.

They sound great, and even though the HFi12D4 looked prettier with the chrome on the edge, and the nice pressure terminals. This one is better because this HFX12D4 actually outperforms them very slightly AND take more power so they won't blow on you at higher watts!

The HFX12D4 are supposed to replace those HFi12D4 anyway.

These woofers are a good alternative to the expensive competition woofers because they SOUND good and they are LIGHTER so the weight won't drag your car down, especially if you have a sporty car you want to keep weight at a minimal.

They're not as loud as the loudest, but they are great for lower power setups as they sound deep.

I would say they are as loud as any woofers around $100 and below price range, and have a nice bassy hit to them.

I am little disappointed with the quality. It didn't produce bass with my Hifonics 500 watt amp and popped hard(not a bass hard) with my Kicker 300 watt amp. I eventually put the speakers in a real small box with an Old School Fultron ME50 amp and achieved mid bass at medium levels. It is what it is for the price. They will produce bass, just not clean, responsive, as a sub should to maintain a companies reputation.

April 24, 2015

I bought 4 of these. One: to replace a sub that I blew. 2: as an experiment to see how well these subs actually are. $110 for all of them, why not? Ill call these subs EXTREME BUDGET SUBS. Baskets are plastic chrome. I have them in a 4-12's prefab separate sealed chambers. I have all each pair hooked up in series/parallel for a final 2ohm load on a RE Audio ZTX 5000.1 amp. According to my amp specs, at 2ohms im getting 1700 watts rms. Using my DMM and OHMS LAW CALCULATOR, I set the voltage so my amp is only pushing out 1600 watts rms. After 2-1/2 weeks of being easy on them to break them in some, meaning keeping volume around 15-18 out of 35.I started pushing them HARD. Volume at 27-30. All 4 are loud as hell. my kids wont get in my car if I put volume at 30. Theyre older teens, NOT YOUNSTERS. My car is a 2007 ford focus 4 door. Playing DECAF/bass songs that have very low notes I dont recommend for ling periods if time. These things heat up quite a bit trying to keep up and I have smelled the voice coils a couple of times. Maybe because I only took it easy on them for 2weeks. I would not recommend putting more that the rms rating through them. ALL IN ALL....im impressed with them for the price. My review is based on the 1 month that ive had them so far and for the price.

March 4, 2012

I bought these about 6 months ago at a retail store, i was scared at first because of the flimsy packaging. Anyhow, these subs run at about 400w rms each, i have two of them. I am running them at about 350w each because of the amp i have and these babies hit hard! They are a good buy if you are just starting out with audio electronics or simply if you just want a cheap reliable product! :p

I bought 2 of these to go in a ported box. They are currently under powered by about 150 watts or so, but they still hit pretty hard in the back of an 07 Aveo5. Would definitely recommend these to anyone looking for some pretty good bang for the money.
Only one small complaint though, One of the dust caps on the sub started to come off shortly after the break in. Fixed it with some thin compound hobby glue. Other than that I love em'. Also would have been nice to have some different terminals than the ones on there but no big.

I just bought four 12" subwoofers and they play exceptionally well and they hit real good for the price of them. If you want to get some speakers for a low price and good quality hifonics are the way to go.

Good Budget Subs

July 24, 2011

Got a pair of these to hold me over until I can afford something bigger/better, but these performed beyond my expectation. They sound great out of my slot-ported box, the only downside is they will overheat if you let them, but with a slot-ported box it is very easy to smell the heat, and turn them down. Longtime Hifonics fan, great subs for such a low price!

The reviews don't lie, these are great subs once you remove the flimsy back cover that rattles, put them in a 3.2 cu ft 4th order enclosure and it's a match made in heaven, they pound the ground..

I looked at these subs for awhile now my cousin got one i hooked it to my 800 watt rms legacy amp no gain in a sealed 1.25 cube foot box and it hit just as hard and my 2 duals do in a bandpass i was amazed on how great it sounded. So i bought my self 2 today will be switching out the duals for these. Get these if you are tight on money they will hit harder then kickers if you know what you are doing.

Definitely worth the money!

September 27, 2012

Just got two of these this week. I was looking for good cheap subs, and Hifonics always seems to be there. They hit hard with the autotek atx1600.2, but i think once i break them in im going for something bigger. Owned some older hifonics subs a while back and they lasted forever until i sold them. Not the best subs in the world of course, but if you are on a budget go ahead don't be scared, they are definitely worth the money and sound much more expensive.

January 28, 2014

Have had everything from W6,TypeR,Comps,CVR,IFINITY,VEGA IT,MTX 8500,ECLIPSE,RF P3,TypeS,TypeE,Coustic, W3,and more, got these ones on EBAY $48 pair and a Boss 1600/2 As I was unemployed and needed my bass fix on a broke man budget was a sceptic.I had them about 1/3 gain to break in at 2OHM. They have better than impressed me for price.Only issues as most people have said on here is crap terminals and plastic dust covers.I Put two in a Obcon labyrinth dual slot port box with 3/4 spacer for extra Cu.ft they Hit HARD. Almost better than CVR'S. EITHER remove or glue plastic basket and DON'T over power & take time break them in. I now have them mostly up on gain just trying to fine tune the bass on my Kenwood Excelon 397 is at -6 and they RUMBLE THE S*#@ out of my 2001 TAURUS. I order another pair so I can run a triple and at $75 for three it will out perform setups TRIPLE in cost. my deck cost more than subs/amp. If you Take time hook up right break em in and tune I have no doubt they will perform beyond expectation.Would probably be best uf have extra $$$ run RF 400/2,KICKER 400/2, Alpine Mrp 500,JL 360/2 OR 500/1(not slash), other wise a cheaper 1500-2000 watts monoblock or 2ch will match best for 2 of these. Watch EBAY AS WELL can get Boss/Power Acoustik/Planet Audio Etc. in that wattages around $60 and the other Namebrands Around $100. I just scored a power acoustik BAMF 2000/1D @ $93 to run three of these should push and not overpower giving a long life(longer than I will have them)

Bought 2 cause they were cheap and this was by far my best decision yet. Running them off a 1600w 2 channel amp they get louder then most of the kid's several hundred dollar systems at school. I would recommend these to anyone, just make sure they are in the right sized box.

Cheap Price = Cheap Sub

October 26, 2012

I bought one of these subs just because I already had a ported box that fell within the recommended enclosure requirements. 1.8 cu ft tuned to 35 hz. First of all, the sub looks good from the front. the rear looks kinda cheezy. Its lightweight. OK construction. Installed in box. Noticed a rattling sound just moving box around on shop floor. Turns out to be the magnet cover. Tried it anyways. Powered it with a PPI Sedona 550.1 which should be perfect for this sub's rating.

The rattling sound got way loud. Immediately removed sub from enclosure and ripped the magnet cover off. That helped with the funky noise.

The sound output of this sub is pretty good for rock. If the box is tuned say around 40 hz, it should slam pretty good for the price. However, when the lows kick in, this sub falls off BAD!!!! Not good for Rap or Hip Hop. Sounded like it wasnt getting enough power, but I know it was.

All in all, not bad for the price, but not good enough to warrant purchasing again. Not really worth the time and effort to install these subs. Just a cheap experiment for me.

Take the good with the bad

May 31, 2012

As the other reviews say, loud sub that makes decent bass for the money. Low end signs off (makes weird noise) so a subsonic filter would be handy with these subs. Bass drum kick hits hard for two twelves though. Quality leaves a bit to be desired as the terminal post on one was not attached right out of the box. Surround let go of the basket on one sub as well after about 10 hours. Nothing a zip tie and some cyanoacrylate glue didn't take care of. As said, for the price I guess you can't go wrong considering I've had similiar issues with high end subs before.

pretty good subs

April 6, 2012

I bought these because I wanted to try a new brand. Never owned Hifonics before. I bought two of these and a Hifonics 1000d amp to put in my 98 GMC Sierra ext cab. I haul my kids around sometimes and had to buy a dual 12" Pro downfire box. I also bought 1" spacers to get a little less depth, and stuffed it with polyfill for more airspace. I still think the box is to small for these subs. The set up sounds pretty good, but obviously not as loud as the 3 MA Audio 12"s in a triple box I had to sell. That thing was a beast. Anyway, not bad for the money. I will say, try and get better terminals for the subs, the stock ones are crap.

Hooked on Hifonics? Count me in!

October 28, 2011

I just replaced a Memphis Power Reference subwoofer with this one. If you don't know about Memphis, look them up, they make quality hard-hitting subs. Well this Hifonics HFX12D4 sounds just as good and may actually even hit harder. It's only getting maybe 200W RMS if that from my 250W RMS amp that's turned up just a notch over half way. It hits very hard, it's not broken in, and it's missing out on 50w+ RMS that I will be giving it after break-in period is over. I can't wait to hear how hard it sounds when I can give it real power. I have it in a generic 1.25 Cu Ft sealed box, it's being powered by a Directed 250d amplifier, and I have it set to hit up to around 125Hz and it handles the high notes just fine. A more than formidable replacement for the old Memphis PR sub that I was running. Hifonics was the right choice.

extremely impressed

March 26, 2014

i bought a set of these to replace some blown woofers in my house cabinets. of course after reading reviews i was curious since a lot of people have great things to say. i'm running mine in some older sear's fisher cabinets with decent crossovers ( not sure on specs ) off of a technics 5.1/stereo and in stereo mode i get about 150 watts per channel.

first you have to rip the plastic magnet cover off the back cause i could tell it was going to rattle just tapping on it. i wouldnt compare these to my L5's in my 7 cube ported box, but wow they sound amazing! my wife was amazed, and my brother in law who thinks he's an audio engineer was thoroughly impressed. i can't speak for the sound in a car. if i had them in a car i wouldnt feed the pair more than 1000 watts at most since they sound so good at lower power. if you are reading this i would say do it. buy one or 2 or what ever cause they sound good and only cost 35 bucks. absolutely perfect for house stereo woofer replacement. i gave it a lower ease of use score since you have to rip the stupid plastic cover off right away

These are nice for little setups to have some thump, so far I ordered 4 of them blew them within 10 minutes, but I have to say nice sound quality came from them, nothing in spl loudness range these came no where close.

The hifonics hfx12D4 is the best subwoofer on the market if your on a budget, yes the price may scare you, you say well with the sub that cheap how could it possibly be true that it sounds to good, well take it from me, i was very unsure of the purchase i made with this sub, i strictly went off of reviews, however, this subwoofer i my home theater sub, it hits. i owned 2 alpine type R 12s, so believe me i know what it means when a subwoofer hits. but the cold hard truth is, this sub is amazing the quality is so precise you cant help but to be cautious. BUY THIS SUBWOOFER YOU WILL NOT REGRET IT!!!

I would recomend these to anybody looking for a system that could beat kicker and stand with jl I have only found one problem with them and its my girlfriend has a hard time breathing so she doesn't like them as much as I do but they have handled everything I've thrown at them not to mention that there rated at 400 watts rms and I broke them in rather well by running them at about half for a month (hard I know but well worth it) now I'm running 500 watts rms through them on a daily basis

Take the chance and you won't be sorry

December 18, 2011

I purchased 2 of these subs, and when i unboxed the subs, i noticed good construction and impedance was correct from the factory on both VC, cone felt pretty rigid, and the overall design was good. I wired the subs to 4 ohms using the supplied handbook with the subs...oh and by the way, if anyone from Maxxsonics happens to read this...please for the sake of humanity just put regular push terminals on the subwoofers. Spade style connectors work but are very annoying to say the least!! In any case, i put the two subs in a ported box i bought off of Sonics, the dual ported box, sounds great, very pleased for how low my budget was of less than $250, i have the 2 Hifonics subs running off of an 1800 watt max Boss Audio Onyx series Amp (Monoblock), 4 ohms-900watts roughly to both combined. I still need to find the right tuning on the amp to get the best sound but overall, I am very happy with everything and I would definitly recommend these subwoofers to anyone looking to get a GOOD not amazing sound from a small pocket, hope this helps!!!

April 5, 2015

I'll be straight forward I only bought these as a quick replacement after I blew my old 12s , good sub for the price well built looks decent and pretty light. I have it in a 2.0^cube ported box on around 400 true rms amp and its demanding more power. However, at 400 rms they seems like they are almost maxed out as far as I can see they are moving like crazy and the excursion is so violent the subwoofers look like theyre going to rip apart and i smell the coils getting hot at about 1/2 gain on the external gain knob I never back off of them until the amp cuts off..they draw alotta power surprisingly! They dont really get as low as other 12's I've had but I also was running a 900w rms Soundstream amp on them. I'll update once I throw my batteries back in the car for the amp and change to my Db Drive 1250. Im just not so confident that it can take a true 800 watts.

Amazing, especially for the price

September 28, 2014

My life is littered with Subs of all sizes and brands. I've probably owned 20 different ones, and currently have 4 or 5 sitting on the shelf in the garage. To me, the mostly sound the same, and I've spent $30 to $500 on subs, and they still sound mostly the same. I always like Hifonics stuff, either old school, or newer (Maxxsonics) era, especially their bass equipment.

Built a box for a friend, and decided to try this sub. WOW, just WOW. A great solid sub in general, but for the price, HOLY COW. The thing just slams, and is responsive enough that it can be subtle too. And its not even broken in yet. Powered by a Hifonics Gladiator 1000W amp, the combo is simply awesome. I can't imagine there being a bass section that is better than this.

Now mind you, this is not built like a competition sub, with cast aluminum baskets, 30 pound magnets, and spiders made of space age materials, but it also cost 35 bucks.

You basically can't go wrong with this product. Anyone who complains about the Hifonics HFX12D4 just has expectations that are completely misaligned with reality. Its a bargain, it sounds amazing, it has terrific texture and can handle subtle, as well as earth shattering bass, and it even looks decent.

I bought 3 of these (under $100) and put them in my car on a SoundStream Rubicon 2500.1d wired in series/parallel and im starting the break in now for the next few weeks before i put the amp to work on these subs. Looks good mounted, don't like the input terminals on the subs very rinky. And the plastic dust cap is just for looks. But it doesn't take away from the sound they produce now. But the shake i feel in my car just tuning the amp: wow. Had 2 cerwin vegas and they didnt shake me outside the car. But these will work till i can upgrade again and for the price buy as many as you want but keep the 4 ohm at the sub, it will burn it out if on a lower independence.

DIY Sub

October 19, 2012

I owned the HFI (previous model) and loved it. This new version is cheaper... and I can tell. I installed one and it buzzed like crazy. Ordered a second one... also buzzed like crazy. It's the plastic cover on the back. Totally pointless. Pry the cover off to fix the buzzing. Then you have a non-buzzing, crappy subwoofer.

Extremely good for such a low price

October 9, 2012

I have 2 of these in a sealed box, wired parallel/parallel to the HFi1500D at 1ohm, tuned to 780watts. These things slam for the price they are at. I was surprised! I now plan on using until I can get a chance to upgrade more.

Hits Hard Enough

May 1, 2012

I have one of these in a sealed box and it's getting 600 watts RMS. It hits the lows really good, sometimes the highs hit hard, but it could be a little cleaner. In my single cab truck it fills the cab with nice clean bass. Just the highs could be better. Haven't tuned it properly cause I havent had the time, just wanted the system in quick for a long trip. I'm upgrading to two 15's so then I'll take the time to tune it. But even for how it is quickly tuned it sounds great.

I've been a car system fan for many years and had alot of setups. These Hifonics Subs are more than you can ever expect from a low priced subwoofer like this one. If you are looking for a setup of two or more speakers these are the best. Great looking, powerful, CHEAP(money wise) and built to last. I have 3 of them and let me tell you they hit so hard my ears ring. Oh yea one more thing Sonic Electronix - a super glue should come with these subs cuz my rear view mirror fell right off. :)) That should tell you (buyers) that these product is worth of money. Thanks for reading this hope I helped.

Amazing Value

December 1, 2014

I have 3 of these in a slot ported ebay box in my game den being powered via a Behringer EP2500 amp wired parallel / series for a final load of 6-ohms (meter reads closer to 5-ohms which is a plus). They only have a few hours on them so they are a little bit stiff still. They are the best value out there as far as I am concerned and Sonic got them to me within a weeks time well packaged and un-damaged. Although not a typical installation, they MORE than fill a 1,000sq.ft. room with authority and will do the same in a car. I am giving them about 1,400RMS and they take it all. My ONLY complaint is the connection terminals (spade style). A little bit of soldering is no big deal though, especially for the price point these are at. Very satisfied and would highly recommend them to anyone.

Great sub for the price

June 18, 2014

I got 2 of these and was surprised with what I got for under forty bucks each, they sound great, and look decent, however as some other people have stated, the plastic cover on the bottom is really annoying. I'd recommend using rubber cement or sealant to keep the plastic piece from rattling on the basket

wonderful addition

February 10, 2014

I have a 15 inch in my Yukon and wanted more db's to pound my chest. After reading many positive reviews about this sub, I decided to give it a chance. I purchased it with the 1truck12 box and added about 6oz of polyfill to the box. The sub does not come with push terminals but I do not mind. It looks good and is built surprisingly well for a $30 sub. I wired it to 2 ohms and have the whole circuit wired to 4 ohms. Boy oh boy! I feel it in my chest now! I have significantly deeper and louder bass! 2 or more of these sub's will shake your ride and make you smile. Thanks Sonic :)

A real review.. This sub is amazing! it is built good and looks pretty cool. I have it powered by the kicker dx250.1. I am giving it about 280 rms and it sounds awesome! Hits the lows and mids like a monster but doesnt really hit the highs. Well worth over 100 bt only paid 38! If youre on a budget this is the way to go, you cant go wrong. I recommend it 100%

I have 4 of these subs in a 10.6 cubic ft ported box tuned to 32 Hz powered by a NXD5500 and they hit hard for being a cheap end sub. They have an awesome look to them, but Hifonics could have made a better basket, and changed the terminals. Overall, it is a great buy.

Bought 2 of these and both blew out almost a month in.... Put them in my Maxima in a seal box with a mmats 250 amp. These woofers are junk!!!! Replaced them with 2 fosgates that cost a few more dollars and it was well worth it.... No more headaches.......

Not Cheap Subs!

March 7, 2014

These subs may be priced very low, but they kick VERY hard. Almost as good as my friend's Kickers. Of course it's not broken in yet so, I think it can hit harder than the Kickers pretty soon. Bought 2 of these, maxxlink amp wiring kit ($29.99 here), Autotek 1000.2 amp, and a Ground Shaker box ($59.99)! All with $200! Cheap doesn't mean bad. Get a good amp, wires, and box and you're good to go! Trust me, these will not disappoint!

Amazing deal for the price

January 4, 2013

Wow is all i could say. Got them from a local dealer in my town, pulled them out of the box, and started beating the crap outta them. Got them to add to 2 Kicker CVR 12's, and was a little skeptical at first. But as they started getting broken in, the more surprised I became with them. Seem to be handling the power quite well. Entire setup is powered by an MTX RFL 600rms, all getting the same power. Amazed at how well a $40 sub handles the power. I don't know what the RFL 600 is actually capable of, but it's pushing the CVR's and the HFX's to their limits. BUT, the only complaint I have about this sub is the dust cap, seems a little flimsy. But other than that, a rock solid sub ready for whatever you can throw at it. Will be buying again for my 8 12's setup that I plan on doing in my F-150.

Better than previous model

June 12, 2012

I have 2 of the older HFi12D4 in one box and two of the HFX12D4 in another, both in parallel so they took same exact power and the Hfi burned up after 6 months While these remained unaffected.

They sound great and even though the older model (HFi12D4) looked prettier with the the chrome on the edge, and the nice pressure terminals,
This one IS better because this HFX12D4 actually outperforms them very slightly AND take more power so they wont blow on you at higher watts!

These woofers are a good alternative to the expensive competition woofers because they have a good SOUND and they are LIGHTER so the weight wont drag your car down, especially if you have a sporty car you want to keep weight at a minimal.

They re not of course as loud as expensive comps,
but they still hit hard for lower power setups and they sound deep.

I would say they are as loud as woofers 2-3X their price,
but the key to most low cost woofers like these,
is to not overpower them .
So listen for their "hit" and back off your gain slightly from their,
for longer listening sessions .

These woofers bang!

April 16, 2014

I purchased these woofers mainly because they were DVC and my previous woofers, JL audio's were not. I needed 3 so they were perfect and the right price. These speakers are the truth I have 3 bridged on a 1500 watt 2 autotek amp, purchased right off of sonic electronics. Even with the bass knob turned down and with the factory radio I have a rumble with the radio on anything past 5. I've only had them for 2 weeks so I cant speak on durability but reading the reviews helped me make my decision and I hope this review helps someone make theirs.

Why did you choose this?
Sonic Electronix Store
Had the same pair of Polk EX Series 12" subs for 12 years (still work great) just decided to try something else. The HFX12D4s are great for the price, but my box is slightly too small for them and they miss out on some of the lower notes. I've blown a couple of them messing around with the amp and the wiring and pushing them to their limits, but all in all a good sub for the price.
