I've been offered one of these subs in trade for a reconditioned Tivo plus money... Problem is, I know they've been discontinued a few years back, and I can't find any 2nd hand pricing info on them at all. This one is about 5 years old and in good condition. Also, 5 years ago, they were getting good reviews, but how would they hold up today? Is it going to sound a bit flabby (despite its THX certification), or has speaker manufacture not really advanced since then? Finally, my current system (which is just lacking a sub to be complete) isn't hi-end stuff at all, but it's excellent to my ear and I'm well happy... I have a Pioneer VSX-811 amp running Tannoy MX centre, fronts, surrounds and a couple of Gale's for rear effects. Will the B&W completely overpower the system, or will it sound as good as I'd like? Ta for any replies!
