Dipole/bipole or direct radiating


I have a 27'x 16' room that will be pretty much dedicated for music and movies. I have heard a lot about what kind of speakers to put for surrounds (some say direct radiating other dipole / bipole). I have Revel Salons and Voice but I am unsure if I should get the M20's or the S30's / Embraces for the back. Any and all comments are welcome.

Thanks

Muralman1, do you have Apogee in a multichannel setup? I would love to hear something like that. I have Vmps all around in my multichannel system but have a pair of Apogee Centaur Minors in my two channel system. I'll bet an all Apogee system with a couple of subs would do it up right, I love mine and may go with another pair someday.
Sogood51, have you been to the Apogee club house? http://audioworld.com/cgibin/sw/forumdisplay.cgi?action=topics&number=1&SUBMIT=Go

there is a member there who uses Full ranges front, Duetta Signature sides, and Diva rears. There are others too. Another member showed a real theater set up with cantered seats, curtains, and all. You can pose theater questions there, and get response from several members.

Keith Yates, of mega home theater fame, is going to pay me a visit shortly. I'll ask him if he knows any other theater folks employing Apogees.
I have been in the audio field over 38 years. I reside in Bellmore L.I. I have been listning to Magnepan speakers & nothing even comes closet to the musicality & naturalness of dipole speakers period. musical marv
