See attached diagram. Because of the constraints of the room, the speakers are ceiling mounted. They are direct firing Ruark Dialogue IIs. I'm about to install the EX rears and they will have to go either side of the projector. Because some electricity pipes make the back right-hand corner of the room void, and because the seats are positioned over to the left of center, I'm wondering whether to position the left rear speaker right next to the projector or in the corner or maybe between these 2 positions. I can't try various positions to see what it sounds like cos the speakers are 9kg each and the girlfriend won't stand there holding them up for me. Where do you think I should place the rear left?
