I have the 774s and 77c from the same line and like them alot. But I'm using 771s as my rears. I remember seeing them at United Audio ( now tweeter ) for $200 for a pair, but I can't use them if they are wall mounted only.
------------------
I use a set of 77DS in my personal home theater. We are working on a review of these speakers, probably about a week away from being published.
I got a steal of a deal on them, and I am pretty happy with them. The only choice I had was to use bipoles in my living room, and I am pretty impressed with the 77DS performance. While they aren't a perfect match to my fronts, I still get good effects and a pretty smooth front to back transitions.

The other bi/dipolar speaker I was looking at is the K4 Tripole from M&K. I looked at lots of rear speakers before settling on the Mission, including Infinity, Boston Acoustics, Klipsch, Polk, M&K, and Phase Technology.

have 77's in my bedrm...love 'em, but have 772's & 77c, ksw12(klipsch sub)..........don't ask anyone what they like, just "voice match, voice match, voice match!"
I have the 771, 77C, and 2 pairs of 77DS. Only have 1 pair hooked up though. Still working on where to put the other pair.
All I can say is, they're awesome.
