Is 9'x11' too small?

And one more comment: The article doesn't mention this but this table also
works for a speaker placement check. The speaker should NOT sit at a
postion with frequency peaks since it will be very easy to excite these room
modes. For speakers "nulls" don't matter as much I think. I just checked my
speaker placement and it is completely fine in my room.

If you need some help or have any questions, please feel free to drop me an
email.

Thanks Rene! I tried the calculator and emailed you a couple of questions.

Jh2os,

I recently turned a spare bedroom into a 2 channel listening room. mine was 11x10, and i love it. speaker placement makes a big difference, as will wall treatments. my room only has one window a 48"x48" and my equipment sits right in front of it.

with just the 2" blinds and no curtain i had to tow the speakers in a bit to get a good image, over the weekend i went to the fabric store and bought some "home decor" fabric, fairly thick, and put up my own curtains. this alone absorbed some of the sound, for the better. i had to set my speakers facing forward, no tow, to get the image back, but it seems better than it did before.

my speakers are about 27" from the back wall and 18" from the side walls. and i sit about 12" from the back wall.

next on my list is to build some DIY diffusor/absorbers to hand on the side walls in the reflection points (mirror trick)

with all that said, i love the sound of the room

look at my system :)

That would be the right size for a full Audio Note system! Or a system based on totem or maybe vandersteen 1Cs! But I'd shoot for the best audio note system (CD/DAC, integrated, and speakers) I could afford and not look back!
