13' x 9' room big enough?

Perfect room for monitors + subwoofer. Monitors can be placed per Cardas or AudioPhysic for imaging and subwoofer placed to load the room with bass. I have a slightly smaller room and the sound is outstanding.

I actually think smaller can be better with rooms because you need less power, which means you can buy better quality.

Quadophile .. REL ST series are the music subs the Q series are for HT. I have a strata3. You don't need much power in a small room.
