B&W ASW1000 active subwoofer. ?

Fantastic sounding active sub, for music or home cinema. Usual B&W quality. 12" long-throw drive-unit, 120w built-in amp with adjustable filtering and speaker/line-level inputs. Really is a beast, goes very loud and low. Good condition, perfect working order. Can send pics on request. Currently located in Hove at my old house, must be picked up in person as it weighs a tonne! Selling as moving onto boat.
