The 250mm (10 in) driver employs an extremely rigid cone to withstand the considerable forces generated by dynamic bass signals and the integral 150W amplifier, features our Bass Overload Suppression System circuitry to avoid the annoying distortion effects that might normally occur should some unexpectedly loud signal threaten to overload the subwoofer. The ASW600 can accept both line level and speaker level inputs and has a choice of equalisation, enabling the response to be tailored to your room.
