I am finding the more I read the more I realize I need bass traps and room treatments for my room. I have flutter echo when I clap my hands and I find that even though my sub is correctly calibrated it can seem to take over during an explosion or sound a little one notish. Has anyone used these? They seem to be the first thing I have seen that isn't ridiculously overpriced. Anyway how much of a different in sound quality to you notice with these things in a room. Forget the dbl charts that people make. I look at those and too me they don't look much different than the original room in some cases, I guess the problem is I don't have a way to compare how the incremental differences sound. Does that make sense to anyone. Do you have to have trained ears to notice differences? If anyone has used these or can answer some of these questions I would greatly appreciate it. Would anyone recommend these? Thanks for the help.

Brotherbob (Rick) has GIK Tri Traps and is planing on adding reflection treatments at some point. He has a thread somewhere, and if you look at my superchunks thread, he has commented on how just by adding tri trap, things have improved in overall sound. Glenn and Bryan from GIK are also great people and will help you. They are always on AVSforum, Musicplayer's EthanWiner forum, and others. In regards to graphs, the main goal is to tame the peaks/nulls to within about a 10dB variance, which does make a big difference.
