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.
The HDC comes with your choice of three different high
performance voice coils. For the street beaters we offer a four layer, round
wound, dual 1ohm or dual 2ohm copper coil. If you’re in need of a straight SPL
woofer we offer an 8 layer, flat wound, dual 1ohm Aluminum coil. To increase
our coils’ thermal handling we use the highest temperature adhesives available
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
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.

Aluminum coil versions are made as ordered, Allow 5-7 working days for build time.
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.
