I will have the option to use an existing horizontal CC or lose my rear surrounds in favour of having three matching towers behind the screen. This will give me a bed of 5 vs 7 channels. I'm tinkering with the idea of doing this and moving the CC to a front middle height channel and laying the extra tower on top of a shelf as a rear middle height channel. These will be in addition to 4 in ceiling speakers. Thoughts? Still just a crazy idea at this point. Really want to try three matching fronts. smile
