Pinnacle's SUBcompact 6, the world's smallest powered subwoofer

Pinnacle Loudspeakers have crammed a powered subwoofer into an 8-inch cube that claims bass response down to 28Hz at -3dB.  The SUBcompact6 subwoofer uses a 6.5-inch speaker that's driven by a 200-watt amplifier and sports the standard subwoofer features: a variable low-pass crossover, line-level inputs, and auto on/off circuitry.  The front-firing design is good for space-saving installations, and for a subwoofer of this size, we imagine those situations will be common.  It also includes speaker outputs for satellite speakers, just in case you want to use the on-board crossover for those.  Small and ballsy, just like you like it.
