I use direct radiating and not bipole speakers. With in ceiling if you want the bipole effect you aim the tweeter away from the listening position to the wall. I didn't do that and have my tweeters aimed at the listening position. I listen to multichannel music and movies and with music the direct radiating is better than dipole. Some companies don't even make nipples and Revel's top of the line doesn't have bipoles. So no, I don't think dipoles are as "mandatory" as you might think. It's more about placement and configuration. In my Preamp you configure dipole or direct. The difference is that direct gives you the ability to enter in distance.
The timbre between speaker brands can be significant. What do you have for fronts? The difference between my Atlantic tech and Revels is significant. They would not mate well at all. Years ago as I was building out my system I had mated my Revel fronts with Focal dipole surrounds and Cambridge sound works rears. Yuk. Anytime there was a surround effect panning across speakers you could tell right away there was something not right. Even the Focals--which are simply excellent speakers--did not timbre match the Revels. I could tell. And they were wall mounted and not ceiling mounted. Remember: I'm hearing you say that the sound isn't good, not the effects.
So, if you can answer "yes" to all my assumptions in my previous post then, in my humble opinion that's what you should do. 1) make sure you like the sound of your speaker brand. 2) if so match it all the way around.
I am not disagreeing with Kal's point and post about in-ceiling vs. wall mount. I'm simply saying that if you need to have aesthetics, in-ceilings can indeed work very well and effectively.
