Hey there, this is my set-up: Focal 816v Focal cc800v B&M AML30 (floorstanding surrounds) Yamaha RX-V3900 I'm interested in a subwoofer, So my dealer said he can give me a great price on the Sunfire TS-EQ12, Well... I tested it.. And I'm not impressed at all. it sure can lift my whole house, but it seems to be 'slow' and like I said - not impressive as the crystal-clear, dynamic Focal's. I thought about the Focal SW800v subwoofer, but the specs are not that impressive - 37-160Hz? :\ Room size: about 45 square meters. Any suggestions? Thanks guys.
