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.

The furnace is in the basement and will be behind the new 4th wall. Hence I want to use double dry walls on both sides for this 4th wall. The furnace is already in place - so I cannot put isolation pads underneath it. Hence I want to know what type of isolation pads to use in this 4th wall being built? Regular fiberglass or the one I mentioned above? I do not have the speaker cables to move the equipment to one side. I can get that done at a later point. For right now, I can get a stand that is lower and place my equipment between the speakers. I also plan to get some Hubble IG outlets at couple of places. Yes, I am ready to do some acoustic tweaks.

Brauser,
I have some GIKs for the bass trap. Hence do not plan to do the wall at 45 degrees. I do plan to get the speakers at least 4 feet from front wall and 3 feet from side walls. It will all depend on how the speakers sound in that room.

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.
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?

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?
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.
I have decided to go with whole house surge protection. This is for the rare case when surge comes to your lines externally. But it looks like most of the surges happen because of internal components like start-stop of machines, equipments, etc. But since dedicated line will not have other equipments hooked up to it, I am thinking that the surge that my audio equipment faces, are all external. Hence the whole house surge protection. What do folks on this forum think?

Does whole house surge protection have negative impact on amplifier performance?
