Lets see your listening room dimensions.

I will admit I have a compromised music room. 12x20x8. My sister has a music room to die for. Asymmetrical as all get out. Angled ceilings with many corners. Walls are rectangular and is broken up by enclosed rooms coming out into the main room. I'm guessing room dimensions. 20x30 with height varying 10 to 15. The most amazing thing is that she has a late 70s stereo with NIKKO Components and OHM I speakers. Are you reading this John S.? It sounds unreal dumbfounding awesome. It made me rethink whats really important in the audio chain. To anyone who is shopping for a new house please take this into serious consideration. Your probably going to have wood floors that are not best for TTs and bass. I have made my own speaker isolation bases which are cheap and not a subtle improvement. Message me for details. Let me see if I can put it on my page here. Good luck. 
Mine is more compromised than yours: 20 x 12.5 x 7 ft.

I agree, a bigger room is worth more than tens of thousands in gear. A high ceiling makes a huge difference!

After I put a lot of care into treatment and positioning, the sound in my room is quite enjoyable. Occasionally, though, I think of the house we didn't buy -- audio room 28 x 18 x 8 and a city-lights view. I feel better when I remember, it was by a noisy road.
Im getting out the tape measure asap will let you know.
My listening (living room) is 16'.5" X 34' with cathedral ceiling. The long dimension includes the dining room & kitchen. Wall to wall carpeting up to the kitchen, two couches, and my listening chair plopped down about 8 feet from the speakers, which are 6 feet into the room, and are toed-in to the listening position.

I use no room treatments, nor do I need any. I consider it to be the best room I've been in for music listening, and I've been here for twenty five years. I had to move my woodstove to a different wall, so my speakers could fire down the long dimension of my room. I'm very grateful for the privilege of having such a fine listening room.

12’4"x14’6"x8’2" height. Stereo is situated along the longer wall. A 2’x5’ louvered, wooden-door closet sits on the stereo’s right flank, shortening the stereo wall by 2 feet.. Speaker placement ignores the existence of the closet, thus making it seem as if the speakers are not centered within the room.  No acoustic treatments other than a trio of racks stuffed with LPs. Wood floor. No cottage cheese ceiling. No rug.

Brand new house. I had the architect and contractor make sure the walls and floor have sound-deadening insulation and that the door is a solid one. I auditioned the stereo along every wall before I declared the job done. And I gotta say, too, that I just love the way it all sounds.
Like everyone's comments. Thats one heck of a sonic room Dan!
I've got all of you beat, dimension-wise  ... 10' x 9' x 8'. Fortunately, room treatments from GIK have turned a once awful sounding room into a very nice sounding one.
My room is now 35.5 X 20 X 8.  I'm trying to get some room treatments in there besides the new wall to wall rug we just installed 2 months ago because of 8 inches of water because of power failure for 12 hours. Had to install an all home generator so my funds have been depleted but room treatments are coming soon.
   I would love to have my room tested for frequencies but lack the knowledge to do so.Anybody located near Wauconda Illinois 60084 care to do some measurements? I just don't want to throw up acoustic panels willy nilly. Have contacted GIK but $5700 shipped with what they suggested is out of my reach at this time. I don't want to do DIY as my building skills suck.

blueranger, thanks for your nice comments. I've recently acquired an SET 845 amp, and had all the capacitors upgraded, and despite being Chinese in origin, it drives my custom Tannoy HPD's extremely well. It's the best my room and system has ever sounded.

Happy I am.

I moved into a new house 3 years ago and so I "planned" (commandeered) one section of the large "L" shaped basement for the audio system.

The section I now use for the audio system is 16 ft wide x 45 ft long.
- Speakers are 8 ft from the 16 ft wall and about 8 ft apart
- Listening position is 8-9 ft from the speakers
- there is around 29 ft of fairly open space behind the listening position
- Ceiling is around 7.5 feet with a couple of 9 inch dropped sections for ducting etc..
- the room is carpeted throughout

I have just started listening for room specific acoustic anomalies ( I had to get the cables right and speaker placement nailed first) and to be honest, I am finding it really hard to find any room related issues.
- I had many issues at the last house, but that room was 2 x 15 x 8ft high, with a large bow window at one end

There is one section of wall that might need some treatment, but this is the best I have ever heard my system sound.

Performers are nicely situated just behind the speakers and the image envelopes the listening position, melts away the walls and disappears far behind the wall behind the speakers.

The sweet spot is enormous - even listening from locations close to the side walls reveals the position of the artists has changed little compared to when sitting in the dead centre position.

I now have two wing chairs in the "listening position" and there are no longer any comments from my wife about me getting "the Sweet Spot"

Live music now sounds like being at the concert in every respect and if the sound engineer does a good job, then even studio recording sound like a live performance :-)

I consider myself very fortunate, because rooms like this can be a nightmare when trying to resolve problems.

Regards - Steve

rlb61  how many panels did it take from GIK to solve the room?

20" deep X 25' wide with cathedral ceiling.  A rug in front of the speakers is the only treatment needed.
We bought this home because my wife loved the kitchen and I loved what would become a great space for my stereo.

31 feet long, 18 feet wide and 12 feet high.

The room has slate floor with wool rugs covering about 75%. For several years no treatment other than ASC tube traps in the corners behind the speaker.

Since then I’ve gone full treatment and although the dimensions are on my side, professional acoustical treatments were a huge benefit.
2 rigs. The Quad ESL near field is one corner of 40’x26’x7’6" with beamed ceiling basement. The other system is the corner at the other end but is actually almost half the space at the other end.
