A useful tool is http://www.bobgolds.com/Mode/RoomModes.htm and look at the results section at the bottom.
so for 11 x 7.5 x 17 the results are:-

Computed Information:
Room Dimensions: Length=17 ft, Width=11 ft, Height=7.5 ft
Room Ratio: 1 : 1.46 : 2.26
R. Walker BBC 1996:
- 1.1w / h < l / h < ((4.5w / h) - 4): Pass
- l < 3h & w < 3h: Pass
- no integer multiple within 5%: Pass
Nearest Known Ratio:- "18) Dolby's optimum ratios for Film & Music Room" 1 : 1.493 : 2.313
Thank you for the link to the room calculator. What does the following information represent?

RT60 (ITU/EBU Control Room Recommended): 184 ms
- ±50ms from 200Hz to 4kHz = 134 to 234ms
- <+300ms at 63hz = 484ms
- 200<RT60<400ms

and

Absorbtion to achieve ITU RT60: 376 sabins

I am going to take measurements down to the inch and see what numbers the room calculator comes up with?

Hi

There had been extensive studies on room dimensions by Bolt and others

For example
http://www.acoustics.salford.ac.uk/a...ontent=methods

A calculator
http://www.acoustic.ua/forms/rr.en.html

Do some research on that, there is plenty in the web.

Cheers
