to better break up modes, you might consider replacing roxull on 1 or 2 sides with 2x gypsum board.
Also, a 3:2:1 ratio is NOT good. Even multiples of length promote 'bad' vibes.
It also might be advantageous to do an OFFSET STUD wall where you will lose 2" of width while having 2 stud walls. Each is offset from the other. BTW studs are typically 16" on center not 8".
Between the studs, you can weave sound deadening material. I don't have a current link, but I saw some very heavy stuff in sheet form.
\Please check out 'room mode calculator' and enter your values and look at the frequency spread. You might be fairly close to a PHI ratio'd room, which is a reasonable starting place.

I apologize perhaps I didn't explain my original post very well.
My room dimensions reflect that I did not use the 3 2 1 ratio. I also didn't think it was the way to go. I used the Cardas golden ratio for my room dimensions.
Picture guy. In order to make the walls more rigid I could do one of two things.. Do 16" on center studs with two layers of drywall, or 8" on center with a single layer of drywall....so I went with double studs and single layer of drywall. The rest of my house has 16" on center studs :)
I am using the Roxull sound proofing BEHIND the drywall to keep the sound inside the room. I am not putting the Roxull on the surface of the drywall inside the room.
So do some of you not agree that I should use the roxull in my walls and ceiling behind the drywall?? I was understanding that is the way to go for several reasons. Please explain if you disagree......
Also, Pictureguy, I am not understanding what you mean. I built one long wall 1" off square. So as you measure towards the back of my room it will move out very slightly. Showing an inch wider in the back then in the front(behind my speakers)
I'm not going into the history of math, but trust me, Cardas DIDN'T invent or discover the golden ratio. Its been around a LONG time. And while the Cardas site DOES mention Fibonacci, they fail to mention that PHI, or 1.618 has been known for a at least 4500 years. The Great Pyramid was built using that knowledge. Either that, or the builders got lucky about 30 times.

One other comment on the room "flair". While it is a good idea not to have the opposite walls parallel, you might want to consider the future when you sell - the next owner may not appreciate "non-square" walls. OTOH, if this is not a consideration -- you plan to be buried in your man-cave like me -- then you might want to consider having the ceiling slightly canted as well. I have about 4" drop over 20' at my place.
with the modest amount the room is 'out of square' I'll bet NOBODY notices even if you TELL them!

IMO 'mancave' is an oxymoron. A listening room should be right up there on the main floor, along with all its other rooms. What kinda 'man' has to do his listening in a 'cave'?

Upstairs, (taken with a cheap oriental wide angle lens and iPad).
So one has to 'toe the mark' to stay married? That's both demeaning and humiliating. Over 20 years ago when we built the house I'm still occupying, I was putting together an office basement to keep away from upstairs conversations and distractions. One of the construction crew, who was still around tidying up loose ends and watching, asked what was I doing. Upon replying, he asked me whether or not my wife would allow me upstairs.
Looks like the photo was taken with one of those 'thru door' security peep-sites.
terrific looking space, though.

I indicated how I took that picture, but suppose you missed it. No problem though, there's a kit available from Amazon having a set wide angle lenses for use with various Apple devices including a iPad (which is in fact what I used):
http://www.amazon.com/Angle-Macro-iPhone-connected-together/dp/B005GTR1CA
(typing B005GTR1CA into any Amazon search bar should bring it up.)
It's a silly set of crappy lenses sold for $6.95 (including shipping). At that price, how good can those 'lenses' possibly be? Nonetheless no wide angle lens I ever owned including 35mm camera lenses could fit all of the image I captured from the distance I used. (I know there's software available to stitch together a set of single images into a single panoramic view, and I even have one such tucked away in a drawer somewhere, but that involves a little work.)
First, when I was into 35mm, I had a 20-35 f2.8 Canon L lens. Maybe 1500$ retail and as good a piece of glass as I EVER owned. When I went to a digital the body had a crop factor of 1.3 which made the lens basically a 26mm.
And yes, both Photoshop AND the Canon 'PhotoStitch' will make panos from individual exposures.
However, my SONY NEX-7 has an INTERNAL stitching routine which is BRUTAL. I have a 14x60 print on the wall which is crystal clear and has amazing detail from corner to corner / edge to edge. The file for that photo is OVER 40 meg. Which once you think about it, ain't all that large a file.
For effects such as the one you got, I'll go with a 'Lens Baby'. Link Provided:
For serious types like me, this is something to own. You can get a variety of 'em, too, so look at the line and decide where you fit in.

The point is that I get no interference on aesthetics cleanliness and volume. Most significant is that the very high volumes don't make it to the bedroom. So that my insomniac self can listen as loud as I like as late as I like.
Besides which I would readily accept that my wife has pants but no one uses whips.
Satie, you brought up 'the' marriage issue. Perhaps the freedom to have one's stereo rig within the house proper should be included in every prenup. :-)
