I've read the speaker placement threads linked in the 101 Setup area but still need some advice on my layout. I'd like to get the most out of my aging system but my room layout limits my speaker placement. I have enough speakers for a 7.1 system. A decent 5.1 set and two Monitor Authority speakers I can use for the side. I'm running a Denon 3803 receiver.
The back speakers are mounted about 6.5 ft high facing down toward the center seat and are set back around 6 and 7 ft from the center seat. The front two speakers and center channel are about 7 feet in front of the listening position and are at ear level. The sub is under a large coffee table in front of the listening position. The main area of the room where everything is placed is 18ft wide (left lamp to plant wall) by 14ft deep (TV wall to surround wall). The entire room has a vaulted ceiling that raises from 10ft on either end to 14ft in the middle.
Due to the room layout the only place I have for side speakers in a 7.1 layout are a few feet to the front instead of directly to the side of the listening position. See red speakers below.
Can I set up a decent sounding 7.1 system with the red speakers placed to the front instead of directly at the sides? Could the audio delay settings be tweaked to work with this setup?
