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.

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?

Power outlets can cost a fortune, but if you look for 'hospital grade' outlets they will be better, and often they cost about 20% of those in the audio trade. Also, you mentioned being stuck with current cables for the speakers. Please consider a trip to HomeDepot and get some 12 gauge speaker wire, its very inexpensive and I bet you will find it much better then what you are using. Ceiling should be acoustical tile, rough pebble finish will tame resonances that a flat, sheet rock ceiling will produce.

Don't worry too much about outlets they can always be changed later. Concentrate on the things that must be installed before the walls are closed in.

Such as, install at least 3 dedicated outlets without any junctions or tie ins. Use at least 10 gauge wire.
You can then install a line for other outlets and a line for overhead or side wall lights.
I also ran cat 7 cable and cable TV and telephone jacks.
If the room may also be used for home theater run the best speaker cable you can afford from the front of the room to the back and sides.

Yes, use insulation inside the walls but don't just butt the 2x4 tight against the concrete walls, leave a gap.

On the ceiling, I used 2 layers of 5/8" drywall, the second layer is glued to the first before final screwing. I wish I had double layered the drywall walls but you may want to.
