Kef Q Series PSW 4000 Subwoofer
Serious stuff. No less than 500 Watts of high efficiency Class D amplifier power, with a 300mm (12") long-throw driver in a hand finished MDF cabinet. As you would expect, bass extension is more than generous - but what's really impressive is the way the LF response is immaculately controlled.

Output level, phase (infinitely variable) and the low pass filter frequency can be adjusted via radio remote control from anywhere in the home, so the unit can be concealed wherever you please.
