Like many people - I suppose - my 'listening room' is far from ideal. I bought a pair of Quad Q11's and they are on a pair of Atacama sand filled stands. The potential of these speakers is obvious, but due in no small part to the rear firing ports, they really want to be in front of a solid wall...well, one is in front of a window and blinds, the other is partly in front of another window (!) and a bit of wall. Would a standmount speaker which is ported to the front be less fussy about what is behind it? Maybe the B&W 685's? Any help appreciated.
