Hello KlipschHead281.
Thank you for the kind words. I have seen the images of your system. A very nice setup as well. The RC64 is unreal! I also like the dual sub configuration. I too have an additional sub. A Velodyne CHT-12. I did experiment with the dual sub setup, but I just couldn't get the response I was hoping to achieve. Then again, maybe my calibration skills are lacking!

I can say that the Klipsch RSW10 does an admirable job, so I'm not too upset about my inability to incorporate the second sub.
