WOW! That guy is a little over the top, but I bet his room sounds good. I would direct you to auralex acoustics. They have some fairly economical systems that are tastefull and effective. Their web site is also very educational. I have to admit, that room treatment is not practical for every application. The "wife acceptance factor" is pretty low on putting bass traps in the living room. However, if you have a dedicated home theater room, I think room treatment is a necessity.
