DD Audio 9512K D1 ESP 12" Subwoofer

DD Audio 9512K D1 ESP - Evolution Subwoofer Performance

Often imitated, but never duplicated.

DD Audio's 9500 series drivers are the kind that other manufacturers try to copy, yet fail. These drivers can handle 1000-2000 watts of continuous power and up to 8000 watts of peak power.

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

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