[charcoal grey]

Thanks for the info Bryan. Just for clarification, I don't plan to cover the sidewalls entirely with 2", just at the first reflection points. I downloaded a free software that helped me locate those. It seemed for the side walls it was for about 12" up from the floor to a total height of about 48" and extends from the screen wall to just before the seating area. The rest of the side walls will be left untreated.

As for the towers speakers I have most of them already. Some were are backorder and I am waiting shipping for the rest of them. I do plan to build risers for the rears and sides though to raise them to a more appropriate height.

For my front wall I was not worried about sound proofing it just making sure it has no reflections problems. I do plan to add insulation within all the walls for the room to help with noise in the adjoining rooms. I realize this will really only help some at low volume levels if any.

I also read some other posts by you Bryan where it was suggested to set up the room with the seating and speakers and perform sound tests to determine the best speaker placement and seating placement. I am going to try to get that done by the end of next week. I just need to pick up a mic and external sound card by then. However, since I don't have all my speakers yet, is it ok to do this in just stereo mode? Is the procedure ever done in a multichannel mode?
