Kenwood designed the KFC-W12DVC subwoofer to deliver tighter, more focused bass, while requiring less power. So what's this mean to you? You'll get really strong bass from a sub that's nimble enough to keep up with the upper notes of a bass guitar, yet efficient enough to run with moderate power. But this subwoofer will handle up to 250 watts RMS, so it will definitely move some air when you want it to. You can wire the sub's dual voice coils for either 2-ohm or 8-ohm total impedance, and that gives you a lot more flexibility if you add another KFC-W12DVC down the road.
