Is a 12' X 16' room big enough for stereo?


Dear fellow audiophiles:
I am in the process of building a house. Our builder went over the floor plans with us yestreday morning and there is an bonus room which I planned on making a dedicated sound room, I am strictly into 2-channel stereo, and my speakers aren't that big, the Thiels CS1.5 driven by Pass Aleph 5. This room measures 12'X 16'. Not sure about the height yet. Is it big enough? What is your opinion?

Thanks
Francis

The last post is right on the money. The key will be the ceiling height. I had a room built in my basement, which has 8 foot ceilings. Though I could have gone much bigger in lenght and widt, I ended up with 14 ft by 12.75 feet after crunching some numbers base don the formulae in The Master Handbook of Acoustics and using the room mode software posted on the Stereophile Web Site. I use SF Guarneri Homage speakers w/ a REL subwoofer and get reasonable flat response down to 20 Hz (measured w/ Rat Shack SPL meter and a test CD), other than a (not unpleasant) bump of about 5 db at 40 Hz or so. After trying many different arrangements, I settled on a nearfield arragnement with the speakers 8 feet apart, 3 feet from the side and over 4 ft from the back wall. I sit about a foot away from the front wall w/ RPG diffusers behind my head. All the first order reflection points are treated w/ RPG foam. This works VERY well!! Net, it's more important to get the room ratios "right" and use sound treatment than to buil a larger room w/ lots of nodal problems.
