Does anyone have this speakers? Do they need a sub or not? I'm looking at this system if a sub is not need (think the fronts have i already!) It will be this system or the B&W (603, 601, LCR600) + rel Q150. But the mordaunt short center may fit the top of the Sony 44px2... And the rears don' t need stands... think the two system are at the same price! Anyone?
