In the past year I have moved my home theater into a small bedroom of about 1000 cubic feet. I currently am running a SVS pc20-39+ sub with ACI sapphire xl speaks. The sub is also equalized by a SVS as-eq1. I listen to music in this room about 75% of the time.

I am thinking about moving my current sub back to the living area and replacing with a sealed Rythmik sub. My question is which sub. I listen to music around -15 to reference and around -5 for HT. For a small media room should I get the F12 or F15? If I get the F15 which amp the 370 or 600 watt?
