Thanks Eric also. Your continued insistence on the importance of room treatments for significant sonic benefits has moved me from buying minimal to treating it like it's a necessary component. But I may have to take a measured approach because I plan to move in a few years and don't want to end up with many unused items.

I got some sound squares. Where do they go? Behind the speakers? Ceilings?
Back walls?
