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

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
The multichannel specs say that your speakers should not be dipole/bipole, but mine are, and they work fine. Besides, I just like the way they sound.
