Do you like them? Build quality? Sound performance? I'm looking at the C-3's for the rears in a 7.1 system. Very good review here turned me on to them: http://www.soundstage.com/revequip/energy_c3.htm (Been waffling between Def Tech, Acoustic Energy, and B&W. Finally settled on the Energy's. I like the connection to the NRC, and they are built by the same "big" company, API, that does Mirage and Athena.) Know a good place online to get them? Thanks!
