Hi all. I have a bi-level home, and I'v moved my AV equipment to the upstairs to where the room is alot larger to where i had it before. It's a living room kitchen combo 24x18X24 - 20 ft cathedral ceilings??? and an open staircase I currently have 2 BIC F 12's paired with Polk M 70s, 40s and a Cs10 running on a Yamaha RX 700. Are the BICS sufficient enough for this space? or what can I upgrade for about $500-1K??? Thanks. -Joe
