Fedx is due to delivery my pair of QSV4s on Friday and I just can't wait to get them all set up. I have a question on location. My TV room is 16 x 18 with 8' ceiling. I have approx. 1 feet behind my sofa/recliners on the rear wall. I've heard that I should place the surrounds facing each other, but I think my best options is to mount them on the rear wall. Any thought from members on the forum. Also do you think I should have purchased the QSV8s for a room of this size?
