You drill the hole, put in a plastic sleve that comes with the screws, then drill in the screw through one corners of the carpet to hold it up. Then do the other side. The holes can be drilled with ease in less than 10 minutes. I have carpet behind my speakers, and on the side walls, and on the floor in front of my speakers. Carpet works great.

I think carpet is a great idea fellas. This wall is probably the most signifcant in the room in terms of potential problems. IMO, every inch should be covered. This could be a costly proposal with carpet. Versus foam, I'm not sure which would be the best way to go.

IRG, see if you can find a tight fit that covers the wall when you are looking for carpet...
