HT room new construction - room treatments, etc


I am building out a basement AV room. I want to devote as much attention to the room as to the electronics, as I am CERTAIN that most untreated rooms completely mask and/or overcome the qualities of all this high end gear we spend so much time and money on. I know this simply from moving the same system into 3 or 4 apartments and/or houses over the years, and noticing the dramatic differences in performance based solely on what's going on in the room. I also know it from playing in a touring rock band for years -the room is far more important than, for example, this high quality amplifier versus that one.

ASC makes a wall isolation system (ISO-Wall) that de-couples the sheetrock from the framing. Benefits are said to include greater noise reduction in the room, as well as prevention of all that low frequency from getting out of the room. Before I invest $2,800.00 in additional building materials and add labor costs, somebody please tell me this stuff actually works as described.

Part II - tube traps and diffusors. Who can speak to the before and after of having employed these room treatments? Was it dramatic? And by dramatic, I mean more so than, say, changing out speaker cables and/or interconnects, because my ears are generally not golden enough to consider these differences "dramatic." (For those who care, the guts of the system will be Anthem AVM-20, Aragon 2007 200x7 amp, and Paradigm Reference matched set of speakers: Studio 100 mains, Studio CC center, Servo-15 sub, etc).

Thanks for the wisdom.

When we built our basement AV room, we used the wall and corner treatments by Kinetics Research. We got the custom color, fabric and design options to fit the room decor. I placed the speakers (Proac 3.8s) at the Cardas positions and two of the Kinetics panels were placed on the side walls at the first reflection points. I have no bass or midrange reflection problems and do not feel I need tube traps or diffusors. We also did not use elaborate wall de-couplers, although we looked into them. I am very satisfied with the room. The nice thing about it is that everything is portable to a new house if we move... we need only paint the new AV room to match the panels. We also saved the Kinetics order forms and our paint color codes for future use, if necessary. Good Luck!
First, we are an acoustical engineering company that specializes in small room acoustics. I would strongly recommend that you consider working with an acoustical engineering service for the design of your room. Every room is different, and one of your questions about should I use the following treatements is very dependent on the room and what you want to acheive out of the room. The room, when being designed from the ground up, should be comprised of certain acoustical attributes (flat frequency response, resonable reverberation times, etc), plus the tastes of the client (some want a brighter sounding or more reverberant sounding room), aesthetics of the room, and overall costs. It is very expensive to buy room treatment that does not work properly for you, and in general, a properly designed room will either need little treatement or have the treatment built into it, thus saving quite a bit of money (perhaps a greater savings than the cost of an acoustical engineering service). Please visit our website at www.rivesaudio.com, you will likely find some useful tools and tips, but I do encourage you to give us a call and discuss the project, even if you decide to take on design yourself.
Michael Green of roomtune fame makes a line of adjustable tuning devices called pressure zone controllers they are very effective easily installed and are available at demo prices from www.audiorevolution.com. I thought the original room tunes were good these are considerably better. Also reviewed on audio asylum and soundstage magazine.
The 4 corner controllers are the most important part of the system
