My local B&M that has served me so well for years is going out of business. I have been wanting to add a sub and they have a couple of deals, but the displays are down and I can't listen to them. They have a REL Q150 for $640(retail 1150) or a Focal-JMlab SW33for $699($1400). Anyone familiar with these? How do they compare to an SVS PB10-ISD or 25-31 PCi? I currently have a Marantz 7200 receiver(fixed crossover @ 100hz) and PSB 5T fronts with a 9C center. Thanks for the thoughts.
