Our subwoofers are not just gorgeous pieces of furniture, but have the guts and internal volume to get the job done efficiently. The Xtreme XD features a solid granite black inlay and a new 15” driver with spun aluminum black cone and a massive 35 lb. magnet structure. This active 15″ driver features an extended stroke and is coupled with a 15″ passive radiator, mounted on the bottom of the gorgeous cabinet.

The front mounted preamp control panel allows continuous adjustment of level, crossover frequency, and phase. A special blend EQ control assures perfect integration with your speaker system. The internal amplifier modules are the renowned ICEpower® design. These extremely reliable, wideband units are of the same type used in our flagship V speaker system.

The 1000 watt Xtreme XD also incorporates a dynamic braking coil which utilizes driver back EMF to counter overshoot as the driver reverses direction or comes to a halt.

Using two or more carefully positioned and phased subwoofers can further reduce distortion, minimize response variation due to room modes and enhance transient response.
