I know I will have to play with things a bit, but based on this basic drawing, which corner would you guess will give me the best performance for the 500. Please note that the recessed HT area opens into a larger room that is almost 900 sq ft. The shorter wall is a little over 6ft long. My M60's are actually not angled in currently, they are next to the screen on both sides. SutterCane thought I might want to place it back near the sitting area?



Sutter made a good suggestion - the next choice is the front left corner.
