DD Audio 9512K D2 ESP 12" Subwoofer

DD Audio 9512K D2 ESP - Evolution Subwoofer Performance

Often imitated, but never duplicated.

DD Audio's 9500-series drivers are what other manufacturers try to copy. However, they never succeed. You can feed these drivers 1000-2000 watts of continuous power and up to 8000 watts of peak power.

Multiple lower suspensions, Free Flow cooling, eight-layer voice coils, EROM and V-Rom surrounds, and a 28mm vent in the pole piece ensure that the driver is durable, performs well, and handles even higher power without complaint.

This driver uses the ESP (Evolution Subwoofer Performance) design, which includes, among other things, larger diameter lower suspensions, a frame with the depth required for the excursion, and a top suspension and cone structure different from standard model series. ESP drivers are built to achieve maximum performance in their size class.
