Actually 12 gauge more than works. It's easy to "want" something or think you need it but there is little science behind 10gauge vs 12 gauge in runs under 50ft and speaker wiring applications. 14 gauge is actually ok. 10 gauge is complete overkill unless your trying to run speakers in a neighbors home down the street. Length effects things certainly.
I would be curious to see some science or data comparing shorter runs with 16 gauge vs medium length runs with 14 gauge vs very long runs of 12 gauge and 10 gauge. My guess is the shorter 16 gauge run would perform best, follow by the 14 gauge medium run. The longest gauge would sound worst, or perform worst and there would be no substantial difference between the 12 guage and the 10guage. I'm just guessing though. I don't actually know this.
I brought up this issue and question because I am designing where I want my AV closet to go. My options are the back, the side wall, or the front wall. My room is wide (24/25feet wide) so I have enough room to put it on the front screen wall and not take away anything. This would lead to convenience of seeing my components; right now my Denon AVR is behind me in my current set up and I constantly find myself looking back to see if the video I am playing on the HTPC is in Dolby Digital+PLII or DTS-HD etc.. or not. This is not displayed on screen. This leads me to want to be able to see my components from the viewing seat. I can make a magnetic cover of black cloth or a door that can close when I don't want to see the lights- I can even automate it. Or they make black out stickers - there is plenty of options to make sure the lights don't bother me when I do not want them.
The idea of shorter speaker runs is attractive to me and makes me seriously consider putting the AV equipment in the front of the theater. It seems easier to deal with the lights and the noise than the super long speaker wire runs and interconnect cables. My theater is going to be 36 feet long, so I would rather give up 3 feet in front for a false screen wall and AV closet, than put the AV rack 36 feet away in the back of the room- which means that my subs and my LCR probably have 50 foot or greater length runs on them after bends and routing through soffits and so on...
The middle ground is to put the AV closet and rack outside the room (but I see nothing which I think I want to see my equipment and show it off ) or put it on the side wall. Side wall but flush to theater wall seems to be the best option. But this also complicates the sound proof effort if I cut a hole in my wall to flush mount the front of my AVR and amps, server, and anything in my rack. That means I need to sound proof the closet, which means double walls and double drywall and GG to keep up with the other walls. Then I need a door to access the closet from the side or back from the other room which totally fawks up my soundproofing again.
I thought such things would be simple but when I think about them they are not so simple
