That's what I figured, but I wasn't sure. I'm happy with it, but I've heard recent advice suggesting front walls benefit from some diffusion as well (Jeff Meier mentioned that during his initial visit to 7channelfreak's room). For a long time, 100% absorption on the front wall was the rule. Unless you plan on doing an acoustical analysis to determine your exact needs, I think you would be fine doing something similar.
