The 2500 'a' Series subwoofers were designed to extract the highest performance from today's power crazy car audio systems. High powered sound systems require high power subs that are built to handle the load. The 2500s match up well with the 500-800 Watt RMS amps driving a single woofer, or the 1000-1600 Watt RMS amps driving a pair. As is with DD's common design practice, the 25s share the same materials as the 35/95s, but with the 2500 motor designed for it's target excursion and power range.

Optimum performance requires a unique blend of design parameters/materials for these subs to hit hard, sound great and last a long time. The motor uses dual 25mm thick magnets sandwiched between 12mm thick, machined steel plates. Internal cooling vents from our Free Flow Cooling System keep fresh air circulating around the voice coil. The 2.5" voice coil diameter has sufficient surface area to handle the long term heat buildup while low enough in mass to keep high efficiency. The coil is coupled to our strong, multi-fiber cone that is reinforced with an epoxy based dustcap. The EROM surround is efficient in both excursion and minimal mass. The suspension follows our philosophy of multiple spider layers for tight bass with low fatigue over the long haul. The lead wires are laminated into these spider layers which further enhance durability and sound quality.

All our subs are hand assembled, rigorously tested and retested. We use multiple glue types and multiple glue joints for all attachment points. We use the most electrically efficient connections, direct copper to copper, the Direct Connect. Cosmetic options include real hand-laid Carbon Fiber dustcaps if so desired.

The 2500 Series subs are the perfect choice for systems stepping up in long term power requirements. The coils are designed using materials with the highest heat resistance on the market and are driven by a precision machined motor structure. The fatigue-resistant parts of the suspension use the finest USA made materials that can be found. These are subs designed to do a job and do it well, to fill your car with the kind of sound that makes you want to keep driving. We've spared no expense to deliver the goods.
