Building a new room


Hello All,

I will be using a contractor to build a new dedicated audio room in the basement. The room dimensions will roughly be 19'X14'X8'.

Three walls are already finished and are concrete walls behind dry walls. I am thinking of making the third wall with 2X4s and double dry per side with Green Glue used between them. Also plan to add 10-gauge wire for a dedicated audio circuit. I believe this should be 20-amp circuit?. Also will not go with can light. Instead would prefer the ceiling spot lights. Do not plan to run a separate ground, as of now.

What insulation have folks used before for sound proofing? I was at Menyards for picking the Green Glue and came across UltraTouch+ denim insulation. Does this work better in dry walls and in ceilings?

What other points am I missing or should be taking care? Please share your experiences.

I don't know if its possible for you, but I tend to like ceilings that have some type of slope to them. Start at, say, 8ft in the front of the room, and have it end at 9 or 10 feet at the end.
I built a room using Quietrock. Double stud with Quietrock 545 on each side. The STC of this construction is 80 dB (very quiet). The Quietrock web page has excellent, easy to read white pages of building a music room with sound insulation. Enjoy your process.
Zd542,
Unfortunately the ceiling cannot go above 8 feet.

Rgwrjs,
I will talk to my contractor on the Quietrock. Thanks for the tip.

I also plan to look into some good AC outlet ports. Looking into Porter Ports. Fellow audiogoner Lak has indicated that he has had very good experiences with Porter Ports. I will also read about others before deciding which one to go with.

Not to worry, the bill for the system and the new room may go over 8ft. So at least you'll have something that high.

For outlets and related accessories, try The Cable Company (www.fatwyre.com). They probably have the biggest selection and they know what they are talking about. They will even send you demo units of anything you are interested in to try first.
Yes, I did look at The Cable Company and inquired about the Furutech GTX-D R.
I had a question on "dedicated line[s]". Why do people have 2 or more dedicated lines? One for amp and one for other equipment?
