13' x 9' room big enough?

Absolutely, if you don't have the speakers yet, go for some that are not too picky about placement (Dynaudio, Audio Physics, most good monitors). Stay clear of dipoles, bipoles and time alligned (Thiel) as they like the listener further out (over 8 feet). Set up for near field listening and you will have good results (Cardas's web site has a nice formula for rectangular rooms).
I am very happy in my 15 by 10 room (Dynaudio Contours 1.8 II), which my ceilings where as high as yours though...

Very interesting suggestions, never tried a setup in a small room with subwoofer. What do you guys think about a REL Q 150 or 200, is this the way to go?

i also have a small room and use a pair of totem model 1's with a rel strata III sub. I would suggest getting a rel downward firing sub instead of the front firing ones. I listened to the rel 'q' series and thought the strata and the other REL's offered more features and better sound.

You might have a little trouble with:
Two dimensions are the same, so that frequency will be reinforced.
The brick wall will be very reflective.

Otherwise, you could have a great mini-monitor setup.

A friend has a very large room, something like 18 x 30 and he uses 5 watt single ended Cary's to drive his Alon Adriana's coupled with a REL Stantor. Amazing sound I must say for such a large room and such a small amp driving them. The music just flows from those speakers and one never needs to really crank up the volume. The REL actually filled in the bottom octave so well we never thought was missing.

The Alon's on their own go down to something like 35 Hz at best and the REL crossover has been set at 25 currently. We tried various crossover frequencies in two or three sessions but settled for 25 (the lowest on the knob) and now the things seem absolutely OK, to our ears that is.

I will need to check the REL site for the downward firing sub they offer.

Thanks for the tip
