Thanks, Frzninvt!
I hadn't thought about keeping the Velodyne, but that's an excellent idea about adding another. I'm very happy with the quality, but was concerned about the quantity.
Also, thanks for the idea about using the RB's for the rear surround. I'm sure they will sound better than the RS-7's. The money I save by not replacing the Velodyne will go for better surround.
Thanks again for the advice and the "welcome" to the forum. I've been all over the Klipsch site, but did not notice it until yesterday.
I can hardly wait to get this all setup.
