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.
