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 to allow at least 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.

bass make me happy
First and foremost this was a tough decision me 2 12’s, 1 15, and will an 18 even fit in my trunk… these were major concerns for me but I chose the 18 because displacement is KING. An 18 has more area than 2- 12’s so that was the deciding factor. When the wife said go ahead and get it because of the sale I typed in the numbers to the credit and ordered as quickly as I could. Didn’t want her to have a change of heart. I chose an 18 not knowing the monster that was about to be delivered. When the subwoofer arrived my wife looked at me with disbelief at the behemoth she had allowed me to purchase. My 2 year then proceeded to climb into the cone which barely moved. The sub was so stiff from the factory it almost felt seized. I was concerned about this not being a good speaker because of the low cost, but I could not find bad reviews on this sub and I scoured the internet looking for bad reviews. I am going to school for electrical engineering and I am in my 3rd year currently. I want to specialize in speaker design. This sub is a monster. I am currently running it in a 6.1 cubic foot box with 105 inches squared of port tuned to about 37 hz. I am running a 2600 watt hifonics amp at about 2200 watts clamped. The sub never gets warm. I always check after I drive to school which takes about an hour or so. I play my music LOUD the whole way. Needless to say I am very and I repeat VERY impressed with the thermal capacities of the woofer and the output it produces. This sub plays relatively flat to down to 31 hz (my f3)… and it murders all the lows. My wife thinks I am going to blow out my windshield because of how much it flexes. My roof bounces like a mofo and it flexes everything. Mind you this is brand new car with sound deadening on all panels and it is still is flexing everything. If there is any doubt in your mind about buying I wouldn’t hesitate. Just pull the trigger and do it.

Love this beast!!
I bought this sub based upon hearing a pair of HDC3 12's and reading extensive amounts of reviews. Nobody says it right about this sub. I use it mainly for daily. But I also compete SPL with it. It is absolutely brutal!!! On both my ears and my SUV. I love it and will remain a loyal customer of Soundqubed for life. I'd love to be able to get my next build going soon!!! If you buy anything but these, you've wasted your money!!!

Beatin' Down The Block.
Just hooked this up today. Only running 1700w & it's LOUD. Got a 5.5cuft box made, tuned to 35Hz, & it's perfect. Hits the lows nicely & it sounds clear as well. Just the kind of bass I was looking to upgrade to. Love it...

2hdc3 18 getting 5.5 cubic feet each running on 3 k RMS. Before I start let me say I have an 88 bronco and I spent a considerable amount of time and money sound deadening it. I fired these things up last night and without tuning on about half power these thing pound! I am most likely going to break my back window and I won't care a bit! These things are amazing and the build quality is top notch. For the price I DARE you to find a better woofer. I should be in the 150's after break in and I don't care what SQ says 1500 RMS is a joke! These things are black holes, they can suck power in with no worries.

Ordered hdc3.118 and a 2000rms amp. Hooked it up and was immediately impressed. Much to my dismay I took it easy for 2 weeks, turned it up more and was impressed once again. Waited a few more days, bumped up the eq, and dropped my windshield mirror. Gain on amp still low and head unit bass eq still negative, not even flat, and it holds its own. Switching a bigger box next week, can just tell she wants more!!! Highly recommend, stop searching reviews, buy it now.

Mr. Silverback
i purchased the HCD3.0 last july while they were on clearence. the sub sat in the box it was shipped in for a year for various reasons. my 1st impression of the sub is very impressive, when u look at this sub it just says Badd Ass!! however, im sorry Soundqubed. maybe i got a bad woofer, because after being hooked up for only 2 weeks, and being broke in properly the sub took a huge shit the other day. it was being powered by Cresendo BC2000 operating at half ohm. installed in 5.8 cu ft3 enclosure ported at 36hz. the gain on the amp was set using a DD-1, and the crossover was set to about 70hz. operating within its WRMS rating, broke in properly, and hooked up correctly. this should not have happened. as this was my 1st purchace from soundqubed, it will be my last. ive seen MTX terminator subs last longer!!! even though the sub has only 2weeks use, of course its out of warranty and im S.O.L. thanks soundqubed. i seems with this company, u get what u pay for.. they make good paper weights!!

Quality speakers for the price
These speakers are very stiff, but in a good way, you know they will last and do more than rated. Lows will crush you, higher bass will rattle your brain! Make sure you have a double baffled/reinforced enclosure because this sub will break it otherwise! These subs are way out of the price range they are sold at, competing with subs roughly double the price they are offered.

Simply Amazing...
I've got this beast running on 2500w and it handles it like a champ. It's also sitting in a box tuned to 34 hz; it hits nice clean lows and loud mid and high tones. Absolutely love this subwoofer, would recommend it to anyone out there!

2 HDC3 18's
Loud sub's that have a broad bandwidth... Just lacking on the sound quality end... Tuned at 34hz I was under the impression that I would achieve better sq but they are still really peaky and has me questioning if the HDC3's should be the ideal daily sub's... Wondering if the HDC4's would have been a better choice. What I can say is I was amazed at how fast I got my sub's and how fast I got replies to my questions in regards to shipping.

Loudest woofer I have ever owned
This thing is huge and amazing, still hits mid, hair buzzing notes, while it flexes out the lows. And I just have 1. Would recommend soundqubed to everyone.

It slams
Put this in a ford ranger with the AQ 1200.2 on 1500 watts and it sounds great. Most "competition" subs are just fart machines yet this is just as musical as it is powerful. Overall very satisfied for the price would recommend 100%

Cant beat them for the price
Ive owned 5 HDC3s now. Had DC 18"s before buying these 2 HDC3s.. Much happier with the HDC3s. They play high (35hz tuning) and still can play surprisingly low. These things love lots of power. Ran 2 on an AQ3500 and now running these 2 on 2 AQ2200s.

Ordered two of these and they came in two days with the provided free shipping. Once I was done building my wall I went to a competition two days later and got a 149.8 on brand new super stiff subs on fairly low power! Can't wait to break then in fully and se what they can really do

Subwoofers
If your reading this review them you must be interested in these Subwoofers. All I can tell you is look no further. I have had all different brands of Subwoofers and I will tell you these are the best. The sound quality and the output is just amazing. I purchase 2 of the HDC3.118 and I couldn't be happier. Thank you Soundqubed.

Bad
I was not happy with this product at all broke it in the proper way and I told him that and the answer from them that I got was that I have the number 1 amp that blows this exact sub up which I highly doubt considering my last sub was an audioqube 18 and that lasted me 5 years on the same setup this sub only lasted a week and a half into break in

Yes
These subs are updated to a design that utilizes a similar basket to the HDS3.1 series, and they definitely look stronger. I haven't gotten a chance to play them yet because I'm doing a wall build and my amps are still shipping, but they look sick with the carbon fiber dry weave cone and dust cap. Customer service with these guys is always great, if not a pleasure. I will update my review once they're in my car.
