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.

Buconero117,
I plan to use Albert Porter's Ports which are cryo Hubble made to his specs. As far as speaker cables are concerned, I have a different view point than you - so lets not go there. I currently have a drop-in ceiling that the previous owner did in the basement, but I want the ceiling higher. I will try to research on acoustical tile.

Ozzy,
My question is - when people have dedicated outlets, do they use them to directly connect the device (amp, preamp, cd player) to the outlets? I plan to use the outlet to connect my power conditioner and then the devices into the power conditioner. I have looked at a youtube video of MIT Z-Duplex, which is a in-wall power conditioner. It shows how the noise is cleaned when using that. I don't know how it would affect the performance of the amps when plugged into such outlet.
The room already has a home theater wires in the front and back. I plan to put a dummy box on those corners and keep them ready if I move in future. As of now - no interest in home theater. Yes, considering the CAT5 cables. What type of insulation do you suggest - regular fibreglass or other alternatives?
2 of my walls - I plan to double layer using Green Glue. I had not thought about this for the ceiling. I read that you have to use isolation clips to decouple the joist and drywall for the ceiling to be really soundproof. So I am not sure if the 2 layers in the ceiling would help me. Most of my listening is done in the night when kids are in bed.
I did look up more on the forums and find that people generally plug a power conditioner into one of the dedicated outlets to connect their digital sources. But they connect the amplifiers directly into the wall outlets. Are you not bothered by the power surge?
Milpai,I am using one dedicated line with my PS P10 power conditioner that has just my digital components plugged into it. That also includes video items.

The 2nd dedicated line is for my Pass Labs Amp. And the 3rd is for my 3 JL Audio F-113 subs.
My outlets are all the Furutech GTX Rhodium and the outlet frames/covers are the Oyaide. (I think they look better than the Furutech).

I used some of the sonex insulation in the ceiling , but I also used regular fiberglass in the ceiling and walls. I installed a exterior steel door frame.

The music is muted outside of my room, but the bass still radiates to the upper floors.
I have read that having a separate ceiling that does not touch the ceiling joist are the way to go to eliminate the bass transfer.

On the question of power surge, I installed a whole house power surge protector in the breaker box.
Ozzy,
Thanks again for letting me know. My contractor also suggests to use fiber glass.
I have decided to go with a single dedicated 20 amp line (10 gauge) with a single outlet (duplex). I will connect my Brickwall into one port and the amp into another. Will do a comparison and then finalize. I plan to go with either the Furutech GTX or the Oyaide.
I am looking to go with Cullen Cables Crossover Series for my amp, since I would need a longer power cord for the amp.
Any other power cord suggestions in the same price range?

I have read tons of stuff on outlets. So I have decided to go with 2 Porter Ports - one for my living room video and other for my basement video.
