The big problem is that a horizontal center channel is a major compromise and isn't the best way to achieve best sound but then, the middle of most cabinets can't house a vertically oriented center channel, nor are many high enough. If someone has the freedom to use the same model throughout, it's a good bet that the sound will be much better than using in-wall or a horizontal center channel. I will say, though- as much as I have been disappointed by so many in-ceiling speakers, the Dynaudio speakers I installed sounded far better than any others I have heard. I know Triad makes excellent speakers, too- they'll also custom-build, based on the application.
