My plan was to get a 5C but I am having a devil of a time finding a HT stand that will look nice in my room and that will fit the 5C.  Trust me I have searched high and low.  Because of this I am considering the 4C. 

I assume the tweeter surround is designed to aid in horizontial dispersion when it is used in the new speakers.  The 4C has the tweeter going 90 degrees from all the rest.  Does this effect off axis highend frequency dispersion?

Hey Russ,

Because it's a dome tweeter the sound field is omni-directional (or circular) so rotating the orientation of the tweeter 90 degrees has no effect on its dispersion.

So since tweeter orientation doesnt effect performance, there is no reason the 4C cannot be used vertically, correct?  So is there any reason not to used three 4C's as LCR, instead of two 4B's and a 4C up front?

While the tweeter is omnidirectional, although spherical is probably a better description than circular, the woofer dispersion pattern is not.  Specifically the sound field is wider than it is tall so when you flip the speaker vertically you will get a more narrow dispersion from the speaker.  It won't make a huge difference, but you may notice a bit of drop out in the mids when you are off axis from the speaker.
