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.

I built a media room and started looking at some of the acoustic companies but was totally turned off by them. Many quoted a high fee just to tell me what they were going to sell me. When I started talking to acoustical engineers I found that most of the prepackaged material sold by these companies were no better than off the shelf products at 5 to 10 times the price. Acoustic caulk at 30 to 50 bucks a tube.
There are many techniques I used. Double drywall on ceiling and walls. Angled ceiling for sound reflection. Rubber strips on furring strips in the ceiling to separate the ceiling from the drywall. On the floor a layer of cork covered by second subfloor. Fiber commercial pad under carpet. Between studs glue in sheets of thin insulation board and use blown in insulation. Where wood meets wood use a concrete synthetic caulk. Good luck
First to comment on Rives remarks I completely agree with his sentiments. Unfortuately I was unaware of him or I would have called him or someone like him for advice and gladly paid his fee. My rub is not with experts such as rives but companies who package and sell at exorbitant prices off the shelf building materials. I was quoted a several thousand dollar fee just to be told what I was going to be sold. Many people wanting to make a major investment in audio/video rooms have been financially successful and don't have time to research these things. This does not justify a rip off. Selling special acoustical panels that are nothing more than cloth on wood framing at a high price ect.
When these people spend this money and then find out they have been ripped the image of the whole industry is damaged. In my case this is one of my hobbies and I spent 8 months researching and calling people around the country getting advice. I wish I could have just called rives and paid his fee because my time has value even though I enjoyed the knowledge. Further I took a great risk doing this myself and really held my breath when I fired up everything only to be thoroughly pleased. Certainly the room can still be tweaked, but the structure is right. Jswarncke you should consider hiring Rives or someone like him. My media room is next my master bath and bedroom. At night when I crank it up you can barely hear a muffled sound in the next rooms. With my acoustic doors closed you can't hear anything elsewhere in the house. I have Revel Studios, center Voice, 4 embrace surrounds, 2 revel sub15s. Major amps to power all. Big sound. Think about what truly good acoustical treatment can do.
