DD 2500 Series In 10", 12" and 15" Power Handling RMS 750 Power Handling Music 1500 Power Handling Peak 3000 Suspension 50mm Nominal Impedance 4 Ohm DVC The new 2500 Series subwoofers were designed to extract the best performance from the newest D-Class amps powering many of today's car audio systems. High powered sound systems require high powered subs that are built to handle the load. The 2500 Series was designed for 500 watt per driver sound systems. This matches well with the 500-600 watt mono blocks driving a single woofer, or the 1000-1200 watt monoblocks driving a pair of woofers. Optimum peformance requires a unique blend of design parameters for these subs to hit hard, sound great and last a long time. The 2.5" voicecoil diameter has sufficient surface area to handle the longterm heat buildup while low enough in mass to keep high efficiency. The coil is coupled to a strong multi-fibre non pressed cone that is reinforced with an epoxybased dustcap. The EROM surround is efficient in both excursion and minimal mass. The suspension follows our philosophy of mutiple synthetic spider layers for tight bass with low fatigue over the long haul. The lead wires are laminated into these spider layers which further enhances durability and sound quality.  The 2500 Series subs are the perfect choice for systems stepping up in power. The coils are designed using materials with the highest heat resistance on the market. The high fatigue prone parts of the suspension use the finest USA made parts 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.
