Product Description

B-Stock

 Stereo Integrity's Home Theater subwoofers are designed to offer exceptional sound quality and low frequency extension. The HT series of woofers are handsomely equipped with all of the features that you're looking for. The attention to detail in their design extends to the exotic CZA spiral cut voice coil former material used to reduce eddy currents along with the 8" Nomex spider with sewn-on leads. To help keep the voice coil stay cool there is a custom tooled vented spacer ring sandwiched between the basket and the motor to allow cool air to be sucked in around the outside of the coil winding's. Other elements (listed to the right) are class leading 22.5mm of Xmax and 43mm of Xmech ensuring plenty of both linear, and peak, travel for those deep bass requirements. You can't get this much linear displacement for the dollar anywhere else.

  1. stereo integrity is no joke!

    Posted by James Mayberry on 14th May 2015

    This review is not of the ht18's but of the ht15's that were previously sold here at car audio bargain. If you have any doubts about this 18 dont! I wish I would have paid the extra $20 for these as the 15's I have just flat out get low and loud! I have them in ported box I built at 3.5 cubes per sub tuned to 30 hertz and all I can say is....do you have flex? These things are the ultimate budget subs!! Though not designed for car audio mine have been taking the abuse from a hifonics brx1600.1 @1ohm for 2months now no problem. Each seeing roughly 700 watts rms. Everything shakes! My mirrors, my dash, hell even my teeth! Just do your research. Nick has been building some badd azz woofers for a long time and these will not disappoint!! Buy buy buy!!!


  2. bassssssss

    Posted by Unknown on 21st Apr 2015

    Have these in 4.2 cubic feet sealed/ported (port plugs) on an inuke 3000dsp. Fantastic combo, had the D2s and the D4s definitely have about 3db boost and seem to work less hard. B-stock look fine a few small scratches on magnet/basket. These things are loud and low. Couldn't be happier other than getting another 2 or 3 of these!


  3. This sub is a beast

    Posted by Rupert on 8th Dec 2014

    I have this sub sitting in a DIY Marty Cube. This thing gets really low and is very clean. Integrated with my system very well. I have 3 of these and may get more. Have been very happy with purchasing from Car Audio Bargain. Can't tell if it's B stock or brand new. Delivery was very fast.


  4. excellent deal on an amazing woofer

    Posted by adam on 30th Oct 2014

    I ordered this b-stock beast on a Wednesday night. It was delivered on Saturday of the same week. Although it is b stock, I didn't notice any defects.

    The performance is totally amazing. This is replacing a 15" solobaric in my living room in a 4 cu. Ft. Box. I'm powering it with a crown microtech 1200 amp and eq'ing with a bfd. All I can say is wow. To see the giant 18" cone move so much is awesome, and performance at 10hz is crazy.

    Thanks car audio bargain and stereo integrity.


  5. As advertised, good experience

    Posted by Tom on 29th Oct 2014

    My order was quick and painless. I talked to a gentleman at Car Audio twice with questions, and he was always knowledgeable and helpful. My order was shipped quickly, and arrived in good shape.

    My driver did have a small imperfection where I could see why it was classified as B stock, but it was small and consistant with how the B stock drivers were described so no concerns or surprises there.

    Good transaction. I'd order from them again.


  6. best bang for the buck...

    These subwoofer is truly a work horse. They are also very well made and qualify as a high end product.
