[b]FS: ATC Concept 4 subwoofer - PRICE REDUCED[/b] BEAST of a subwoofer, from personal experience better suited to music than movies - incredibly accurate, tight, controlled, and dynamic - though in a small- to medium-sized room it will kick serious ass for movies too. Specs are as follows: * 12" ATC driver (very meaty, ~13kg alone!) * 650-watt RMS quality ATC amp (1000-watt dynamic!) * 58cm x 50cm x 50cm (H x W x D) * 54kg total weight!! Not something you can pick up on your own! * Dark grey gloss finish (gorgeous, matches ATC Active 10 and Active 20 cabinets) Official website at [URL="http://www.atc.gb.net"]www.atc.gb.net[/URL], though there isn't much info on the C4 sub. [b]£1100, but will consider offers (£2000 new)[/b] Unit is approx. four months old and in perfect condition. Selling because my room is an absolute beeyatch when it comes to bass - sucks the life right out of it - and I feel I need to change to something that can churn out monster SPLs, like one of the big American subwoofer beasts. This sub is sadly a bit too subtle and refined for my room. Ideally would be collected from Edinburgh, but I have the original crate (yes, crate!) so I could conceivably ship it elsewhere, though the costs would be entirely up to the buyer. If you would like a demo, you're more than welcome to come 'round for a visit. Cheers, Dunc P.S. - Note, this really is a monolithic sub (it's about the same size as Godzilla itself, the Velodyne HGS-18!) - there's no way you'll get this past your significant other without prior approval, guaranteed!
