I had the projector mounted to the ceiling but it overheats. It has a fan in it but it doesn't work that well up higher I guess. It is an Optoma HD20 and does a pretty good job actually but I'd like to get an Epson. To answer another question above, I have only measured from the back and side wall. I have not measured to the listening position which is what I will do today. I moved them in some last night but will spend the afternoon/evening playing around with everything. I am going to try to bring them out a little more as well and see how they sound but I do think my not measuring them to the listening position is key. Thanks guys for all your help.
