RonK

Hello, I recently purchased 2 RF-62 towers and one RC-52 center channel. I am running an Onkyo 709b amp with athena BS1-1 surrounds. I purchased a Polk Audio PSW505 on boxing day but I am not too sure about it. I am thinking about the matching Klipsch SW112B or SW110B instead. Just wondering if anyone has had any experience with one or both of these subs and can give me a good honest opinion. Maybe even other subwoofer suggestions? Thanks a lot for any of your help.
