I own a pair of these, i bought them for some fun about 3 years ago and still haven't sold them, they are fantastic for home cinema and if you can get them for £500 or less a bargain too, be warned though, they are monstrous, think cerwin vega bass/volume but much better quality, i'd buy them for rears if i had enough space and no wife.
