Description Product Description The Focal Sub6 is a startlingly effective active subwoofer that delivers tight bass all the way down to down to 30Hz. Driven by a hefty 350 watts, this 11" sub extends your low end in a linear fashion at any monitoring level. The Sub6 offers the flexibility of 2.1, 2.2, or surround LFE configurations, while its onboard highpass crossover, adjustable phase, and level control make for smooth integration with your full-range monitors. There's also a footswitch input that lets you easily compare your program material with and without the subwoofer - a very useful feature!
