And, if so, do you like them?
I'm using these:
http://emotiva.com/erd1.shtmI put together my room and finally got all the kinks out (including two shorted channels). I'm running a 7 channel system, with the Emotiva's set up as they recommend (left/right dipole for the speakers at the side of the room, and left/right bipole for the rear surrounds).
You can see one of the surrounds here (the black speaker on the wall in line with the couch):

The other two speakers are here:

The front looks like this (one day, I'll have a wood valence to match the woodwork and cover the screen; those blackout shades cover a sliding glass door):

I used to run a 5.1 set up with direct radiating speakers (Mirage or Linn). I've only listened to a few DVDs/Blurays for this system, but I'm having trouble liking this sound. The sound on the sides and rear is very diffuse, so diffuse that it's like the sound isn't there (although if you go up to speakers, you can hear tons of sound coming from them, but going to the back/front/sides of the room and not "into" the room).
Is this something I'm going to learn to like? Anyone have a similar system or use bi/dipoles and learned to like them after a while?
