The HDC series isn’t just some off the shelf woofer designed in the virtual world.  It is the product of over two years and hundreds of hours of real world research and development. Many of the HDC’s features are only found on woofers costing twice the price. When compared to our competition the HDC series woofers have more cooling, more throw, more motor force, and stronger cones. These woofers work great in everyday street beating or all out gut wrenching SPL builds. We have spared no expense to give you the best subwoofer value on the market today.

HDC Coils

The HDC comes with your choice of  a four layer, round wound, dual 1ohm or dual 2ohm copper coil.

HDC  SUSPENSION

Suspension systems are generally a weak link in a woofer design, and often the primary reason for woofer failure. Over time, especially in high power applications, suspension begins to sag and as a consequence it can no longer control the voice coil’s movement. This generally results in a torn suspension or smashed voice coil.  To avoid this we use a multiple spider configuration engineered to maintain rigidity over extended periods of heavy use. We also hand glue our triple joints to allow for better glue penetration and saturation of the high stress areas. 

HDC DIRECT CONNECT LEAD WIRES

High excursion subwoofers require a lead wire system that doesn’t flop all over the place or break. We use the direct connect system (no terminals) because it works the best. With our direct connect system you get no annoying lead slap noise, no rips or holes burnt in the spiders, and no flimsy lead-in wires.

PLEASE READ: In the pursuit of offering the best in DIY car Audio we ask that you read about clipping, what causes it and what the outcome is. 

We recommend allowing several weeks of playing time to break in SQ Woofers, full break in may take many months. DO NOT  play subwoofers at max amplifier power in the first couple of days, give the suspensions a chance to loosen up. As the suspension breaks in, the subs will play lower and louder.

Low end monster
Purchased 2 12 inch hdc3. I constantly hear soundqubed subs do not play low. I finally got mine hooked up to my crescendo encore 4.5k at half ohm. I have a headache now. Maybe people are putting them in the wrong box. I don't know. Maybe they have crappy amps. I don't know. I have mine in a 4.5 cubic foot box tuned to 32 in a hatch. If anyone needs help on a box go to 12volt.com. To sum it up these woofers slam and I couldn't be happier. And they aren't broken in yet.

Best Subwoofer HANDS DOWN, VERY impressed PERIOD, BUT IT
I have been in car audio for over 20 years now and have used almost every brand, from old school soundstream to Precision power art, JL audio, KICKER, Old school Orion, Kenwood etc. This SUBWOOFER for the money is by FAR better than any mainstream subwoofer. This one 12 inch sounds like two JL 12s easily. Destroys the Kicker COMP Rs I had running before. I matched this one sub in a custom enclosure with a Soundstream 1500 watt RMS amp, and it doesnt break a sweat. It is so clean, it rattles every bone in your body and the key here is it is CLEAN. Also not power hungry at all, compared to the Kicker and JL subs. Stock alternator, high quality battery, but no problem eats up 1500 watts and loves it. This is the most impressed I have ever been in a car audio product in my life. I havent had it long, so will see about durability, but from what I can see so far, not much would beat this for the price. Hell of a job soundqubed for life now.

2 SQ HDC3 12s
These subs are extremely underrated. They can take much more than what the recommended power is. The are the most clear subs I have ever owned. These things come super stiff are extremely loud out of the box, but every day I can hear them getting louder and louder.

very impressed
So after looking at these and reading reviews on them for almost 3 years, I decided to give them a try. I've read alot of people saying that these woofers didn't like to play low, and after having them, it's all about how you set them up. My trunk build right now peaks at 30hz, these hdc's are killing everything from 26-34. Even with porting not being right for them. Can't wait to rebuild and see how they do. These are very very solid woofers With an outstanding price. When I received mine I was shocked at what I got for 280$ a piece. Build quality is awesome! If you have the space for these, you can't go wrong.

Hdc3.112
Words can't explain how loud this sub is.... I have one 12 now with a ported box built for the sub specs on a Memphis 1500 Rms and it hits harder and louder then the two 12s I had in it before I bought this one.....I plan on getting another one these subs and getting the 4500.1 to push them.... I'm very happy with this sub....its deep and loud.....who ever wants to get this sub don't waste your time thinking if you wanna get it or not just get it cause it's worth the money

Great Sub recommended to anyone very loud and clear
I put in my hdc312d2 little over a week ago got it wired to 1 ohm on 1500 watts and it slams I do alot of driving so alot of booming to everyday gets louder still a long time breaking in to do but love it got it in 2.5 cube box in a dodge dart turns it into a tin can lol. This suspension is wicked stiff when the sub arrives but stating to loosen. The direct connection leads are awesome as well of no extra cost IT dose make a difference. Iv had many subs range from $30 to $600 and I got to say this Soundqubed is the BEST Bang for your Buck!! For $239 sale and $279 and performance of a $600 subwoofer in my opinion! Plan to buy more for my vehicles also great Soundqubed decal for Ur Windows. If Ur debating on SQ subs like I was for a long wile get some u won't be disappointed!

S10 gettin loud
Amazing sub!!! It's in my s10 in a 6th order bandpass first chamber is 2.1ft^3 tuned to 58hz firing into the front chamber that 3ft^3 tuned to 33hz. I have it on a hifonics Brutus 2200.1 at 1ohm on 0ga electrical. Right now on stock battery and alt but upgraded those soon. But this is the best and loudest sub I owned yet. Definitely gettin three more next year for a wall build. Recommend to anyone and Zach knows my buddy Brandon Henley really well which is a big plus!! Thanks for the great quality and price soundqubed!!! Soundqubed FTMFW!!!

Best Subwoofer Purchase EVER
Honestly, if you have the money and time to do all the work of wiring, building a box, and hooking up these woofers, BUY THEM. It cost me around $1200 to get everything i needed for this upgrade so my car would function properly due to the large power demand, but THESE THINGS TURN HEADS ON THE HIGHWAY!!! Do yourself a favor and buy a pair of these.

Honest truth
For six months I been debating whether or not to go with soundqubed because of all the good and bad things people were saying. I finally decided that despite what people were saying, I made my choice to purchase two HDC 12. The shipping was pretty fast which is always a plus. When I opened the first box I noticed that the sub did not have the holes cut out for the box. How does that happen. No big deal tho I can drill my own holes. Everything else seem to be on point. These subs are monsters. I couldn't believe how heavy and beefy these subs where. And boy do they get down!!! By far the best sub I have ever owned. these bad boys have the best SQ I have heard out of a SPL subwoofer. I'm glad I went with Soundqubed. You guys have won my heart

Best sub
Got a regular cab Silverado. Used to have a hds212 and decided to upgrade the whole system. Went with this sub in a custom box tuned to 35hz powered off a crescendo symphony 1500. This thing hits the lows! My cab flexes all day now. Only bad thing I can say is that it's tearing my truck apart. Soundqubed FTW!!

Worth every penny!
Just picked up a pair of these. They are beasts. Put them in 5.4 cubic feet tuned to 36HZ. It hits hard. Even with the tuning a little higher than I normally do it CRUSHES the lows. I am feeding them 3200RMS but I am sure they could take more.

12s Killin it!!!!
Im really not much into 12s. I love 18s an 15s for really low bass. but eventually want to run 6 of these on like 12-15K. well I built a tube ported fiberglass box that ended up like 6.6 cu. ft. net an hit lows great but not super loud. so few days ago I built a smaller 4.75 cu. ft. seems to be around 42 hz. an it can make ur nose feel wobbly like in back of 01 Tahoe on Skar Sk 4500. I highly recommend these or any soundqubed subwoofers for hard loud great sounding BASS!! I own pair of hds3 12s also.

HOLY CRAP! BEST SOUNDING SUBS FOR THE PRICE!
These have got to be the best sounding subs I've ever used, bar none! Especially for the price, its unbelievable! I still can't believe what you get for the price of these things. The build quality of these drivers is great, they're heavy and you can just see all the attention to detail in the stitching and wiring. I've been running just one HDC3.0 12" for a while, on an underpowered amp with a box that's too small. Still sounded better than the two 12" Kicker CompVRs I was running previously. I decided it was time to quit playing around, and get serious. I pulled the trigger on a second HDC3.0 12", along with a large 5.0 cubic foot dual 12" box port tuned at 34hz, and a new Hifonics Brutus BRX3016.1D amplifier. This is all in a 2011 Crown Victoria LX. I've got the trunk and deck sound deadened, along with a Pioneer touchscreen head unit, Infinity coaxial interior speakers, and an AudioControl OverDrive Plus line driver. I suspect once I get the system all installed and dialed in, I'll be banging the loudest system in my neighborhood....LOL. Soundqubed FTW....the MF WIN!!!!!!

I have one hdc3 12 dual 1 wired to half ohm on a Q1-2200. I haven't even broke the sub in or turned my amp up and this system slams harder than any others I've ever had. You can't beat the value that you get with soundqubed. SQ FTW.

Amazing but,
These are the loudest speakers for the price.got 2 and paired them with an soundqubed 2200w mono amp and they are amazing,but they are so loud they will rattle everything so I suggest buying their amateur which fixes the entire rattling and makes them sound even louder

I bought air of D1's at the beginning of March. I just got them in my car yesterday. Running them with a soundstream rub1.2500 at 4ohms. Clamped pushing 1054 rms or so in an Atrends box. These things move some serious air and I haven't even scratched the surface or broke the subs in. I have another rub2500 and will be running them strapped with 4 kinetic hc2000's and an Orion xtr4r crossover. (Switching to 2 orion xtr2500's when readily available). 3400rms will put these things through their paces. These destroy my phoenix gold Ti elite 12's. A must buy for bass heads at an awesome price point. Keep it up SQ and u may be shipping 2 4.0's next yr.

I bought 2 of these for a customer who wanted to stand out. I built him a very efficent 6th order and put them on a hifonics 2400 brutus and wow. these are air movers and not even broken in! im sure once they are broke in they wil be able to hairtrick and thats from a trunk. for being so massive they are very musical which also has alot to do with enclosure but none the less I love em.
