Ok, here's the thing, I currently have a Klipsch RW-8 and i'm very happy with it, the only thing is, I want something louder and deeper, I had a chance to hear the RW-12 the other day and I really enjoyed that sub, I never had a chance to see/auditionne a HSU because they're really rare over here in Montreal (Canada). Although, I'm able to get both of them at the same price, I would also consider the SVS PB-10 ISD (if it was actualy possible to get them in Canada). My budget is around 700-800$ CDN. It's going to be 80% music and 20% HT, I listen to rock/hardcore/drum&bass/trance so I like something that can go deep and LOUD!! hehe, anyway, I'm waiting for your recommandation! Thank you Between, Klipsch is my first choice because it is 360watts vs 250watts (HSU) Thanks!
