Active subwoofer system

The EX1.2MkII is a small single 12” active subwoofer system. Employing passive cooling, the EX1.2MkII boasts output that belies its compact, low-profile cabinet size, as with all KV2 Audio products. The enclosure dimensions make it ideal for discreet installations, as it can be installed either horizontally or vertically under seating and in furniture surrounds. Featuring KV2 Audio’s switching amplifier technology,  the EX1.2MkII delivers tight, fast, and controlled bass response at very high output levels from an impressively conservative cabinet footprint.
