I just set up a new home theater and am getting a really good picture but the sound/acoustics are really bad. Words are almost imperceptible, completely drowned out by background sound effects and washed out by echoes. I tried to watch 'The Dark Night' last night and couldn't even make it half way through. It is hard to enjoy a movie when you only understand about 30% of the words. I think the biggest problem is that there is too much echo in the room. It is a 20' X 30' X 16' high converted garage. The walls are concrete block. My new setup consists of an Epson 8100 projector and a 124" screen that is about 18' from the projector. My receiver is Denon AVR 590 with HDMI output/upconversion or whatever you call it. For speakers I am using a 5.1 system and am using some Sony stand speakers that I have had for about 5 years. I don't know any specs on the speakers off hand. They sit close to the viewing area in the rear and near the screen about 16' away from the viewing area in the front. Before I go and buy all new speakers I thought I might ask for suggestions on fine tuning the set up the way it is. Thanks in advance for any advice!
