Just one thing, Al, a room is not Just square footage. It is Cubic Feet. 8x12x22 is only about 2200 Cubic Feet and not all that large as such things go.
My LR is 'big' in that it is nearly 5000 cubic feet. Ceiling makes it so, being from 8 1/2 feet at the lowest to 11 or so at the central peak. Very odd shaped with 8 asymmetric walls. At least is sounds
good for bass without going into corner traps and clouds.
Your room, if an 8 foot ceiling is Close to a Phi Shaped room, where the ratio of lengths of sides is 1.61 : 1 So, an 8 foot height is just over 12 foot width which works out to about 20 feet in length.
Go to the Cardas site and look up 'Golden Ratio' or whatever they call it. Than if you REALLY want to drive yourself nuts, look at the math behind the design of the Great Pyramid. Yep. They had a grasp
of this over 4500 years ago.

Not a room sound engineer but two things: 1) I have stayed at a Holiday Inn and 2) I added two GIK sound absorption panels at the first reflection point(front side of each speaker) and the bass tightened up as did the imaging improved.
I am not saying this is the holy grail answer for every room just that it was a worth while investment for my loft system.(see signature)

Better rooms yield better sound at ALL levels of this 'hobby'. or whatever it is. If I had a Big Budget and was starting over, I'd spend at least a Portion of the $$$ on fixing the room. |

You are 100% correct. The room makes or breaks the system. Speaking of building a dedicated listening space, a friend of mine in New Jersey had a company design and build a 20 X 14 dedicated stereo listening space onto his house He invested well over $150K before any equipment cost. That was to build the room and achieve the desired listening space performance. |

Clean Sheet Design? You're talking REALLY Big Bucks. Double hung walls with sound absorbing materials inside. Not only wall treatments, but 'clouds' (ceiling treatments)
You can get into Non-Parallel walls. Double Doors leading INTO the new room. (Think Airlock for sound) 2x Sheetrock on 2 adjacent walls?
You'll need a 50 amp panle JUST for the new room with dedicated circuits for AMPs and than low level gear. Lightning arrestor where appropriate. All 20 amp circuits with 10ga Cryo'd wire. Hospital Grade outlets. Proper furniture. (another can-0-worms) Floor Coverings than become important. Want a dead zone at the speaker end? Minimze standing waves in original design?
If you add enough Square Feet (Cubic is real measure) you might need upgraded HVAC, too.
Zoning? Permits? Contractor evaluation?
Details...Details...Details.
And the consultant for such a room? I've asked local builders about 'building a sound room' and they haven't a CLUE even though most say They can and HAVE built such a room.
I'd have started with 8 1/2' ceilings, the 14' width and make the length 22'. That is close to classic 'phi' ratio.
150$Large is a sum beyond my ability to comprehend. I'll bet your Buddy's BoomBox never sounded better!
