How would you rate your listening room?


I think most people visiting Audiogon are familiar with Stereophile's equipment rating system. So, more or less using that system, how does your main listening room rate as to potential music quality? I've given this some thought, and at 14'W 22'L and 7.5'H, I'd rate my room as "B", mainly because of decent dimensions. With the addition of ASC treatment(s), which I've done, I'd upgrade it to "B+", and if I were to go to good quality monitor speakers (which I won't) with bass to about 40HZ, I could maybe upgrade the room to "A-". My room could never be full class A IMHO because of low ceiling height. I'd like 9 ft. ceilings and a 2-3 more feet of width. Also, as I like good sized near full range speakers (I have Vand. 3Asigs.), I doubt I'd be willing to go to smaller speakers. Have others thought of rating their rooms? Cheers. Craig.

I give my room a solid "B". Its dimension are 33x14x8.5 with wood floors and drywall over brick. It's slightly live sounding. I use acoustic treatment (11 various roomtune products). The room has a deep notch at 50Hz and a boost centered around 80Hz. Although noticeable, neither is particularly bothersome. The ambient noise level is typically somewhat high at 53dB (C weighted). It's mostly low frequency rumble from high overhead airplanes and nearby trains. I live more than 10 miles from O'Hare (not in a direct flight path either) and the nearest train line is 1.5 miles away. Apparently, low frequency sounds can travel quite far.
I forgot to rate my room on the above submission. I give it a B+; I can't in all honesty give it an A because I Have 2 large windows at one end of the room & glass will vibrate. I am waiting for my better half to get some drapes which should help.
garfish, heard the vandy 5's this last weekend. so much like our 3a sigs and yet sooooo much better. no resonances from the boxes, bass to die for (and i've got a rel stadium II). just seamless integration from top to bottom.i was drooling. and the guy selling them did'nt even have them set up for optimum effect.
My room I think is about a B. Looks like:

the black boxes are the speakers, in reality they are toed in slightly. The blue box is my listening chair.

The room is about 8' high, 14' wide at the narrow spot, and 20' long. The alcove in the right-bck has two doors in to adjecent rooms, normally closed. The front-right area is open to the second floor on the right hand side, and just open on the ground level in the back.

Floor is tile over concrete, left wall is about 90% glass. Back wall is drywall, as is front. Right wall is brick. The floor in front of the speakers is covered with a few rugs, as is the floor behind the listening position. I recently hung a rug on the back wall. Turned out that with the rug about 2" out from the wall, the room became absolute magic. Frequency response from 1kHz to 15kHz is +/- .5dB in almost the entire room... Stereo imaging from the listening position is absolutely amazing. I see the singers, I see the instruments, the sound extends beyond the speakers, and with my eyes closed I often times am not able to pinpoint the speaker locations. I love it.

The ceiling is hardwoord planks with beams haning down 8" at 4" wide at 8' and 16' from the front of the room.

I rate the room a B because the combination of the room and the speakers have a pretty serious bass issue, about +6-8dB at 50 and 63hZ or so, and a dip of about -4dB at 125hZ. The whole bass region is a bit +, about 3-4dB on average. This seems to be partially due to the speakers (Vienna Acoustics Mahler) and partially due to the room.

I have not yet found appropriate methods of dealing witht his bass problem. Just last weekend got the rug on the back wall up, which made a big difference. Build some bass traps, but they did not quite work like I expected. So, maybe with a bit more work can get it to a B+.
