1.)anybody know anything about the ccm 817?? worth the price difference between them and the ccm80?
2.) I have 12 foot celings. Too high for in-celing surrounds?

I am also considering ccm80 as my rear surrounds. For me, the 817 was not worth it because these are "just" surrounds. I do not place too much value on them. I am more of a stereo guy with some occasional HT. I think its overkill to use really expensive speakers as surrounds, unless you are listening to a multichannel cds. Just my opinion.
