Building an audio room - 12x22 - electrical plan?

You'll probably need Arc Fault Circuit Interrupter breakers for each circuit.

I just did my 10x20 room. I had one outlet for AC and lights, one just for audio that has 8 outlets. Besides all the suggestions, one thing I wish I should have also added was running 2 sets of opposite phases into the audio outlet for noise cancellation.

Pay particular attention to the construction phase for quality work. If you can stagger the studs with any common walls that would help with sound isolation. Also seal any air gaps with acoustic calk such as baseboards, outlets etc. Sound will travel!

Might I suggest you consider building your listening room to the golden ratio, which is 1.618:1? This would require minimal physical, but acoustically significant changes to the proportions of the room to avoid standing waves and enhance the sound at all frequencies and locations in the room.

To modify your present plans to the golden ratio, you could modify as follows:

If your longest dimension must be 22 ft, your short dimension would be lengthened to 13.6 feet and the ceiling would be 8.4 (~ 8' 5") high.

If 12' must be your maximum width, shorten the long dimension to 19.4' (19' 5") with a ceiling height of 7.4'.

This should make the speaker/room interface easier to tune, minimize standing waves and sickouts, and require less room treatment for a full, natural sound that is consistent throughout the room.

After all, George Cardas built his cable company on this principle.

Thanks for all the responses. I will keep the thread updated as I proceed to build along budget lines. While I would love to build the Cardas plan, I can't drop the ceiling or shorten the room.
