My first real subwoofer was an SVS 20-39 PCi. Today I'll be taking delivery of an SVS PC-2000 Pro. This will be going in our living room which has been running just a 3.0 system since we moved here a little over four years ago. Hopefully this concludes my subwoofer journey as I'm very satisfied with the dual Rythmik's in the HT and this SVS should be more than enough for the intended task. I'll post pics when I can.
