JL Audio CP108LG-W3V3 Powered Subwoofer



This incredible MicroSub subwoofer system delivers the kind of output and extension that is normally possible with only much larger systems. The key to its performance lies in the precise tuning of its 8W3v3 subwoofer driver into an efficient slot-ported design.
