I just treated my home studio with room kit # 3 from Gik Acoustics and what a difference so far. Money well spent. http://www.gikacoustics.com/index.html I have low end response in my room that is about 5x bigger. This is a good thing. Eg: before the treatment I had a Sadowsky 200 watt all tube bass head driving two 4x10 cabs that had to be almost cranked. Now it blows the place away with less volume. Drums have balls and force. The forest creatures are scared. Glenn (of GIK) answered my emails quickly and was patient with the most basic novice questions. Like...."if I turn the volume knob up wil it get louder in the room?" OK, not that bad but the guy was super helpful and once I decided to place the order, the stuff arrived earlier than expected. I'm posting this to let you guys know about a a great guy in the business. I'm getting nothing from posting this. Just spreading the word. Even if you don't get his stuff, his website is very educational and well written. .
