It's definately a case that my buddy and I have debated for a while now. We were using a pair of ATC Active 20's or Active 50's for the center channel. One on each side of the screen makes for an amazing image of the voices coming out of the direct center of the screen, which can only otherwise be achieved w/ a perforated screen for people w/ projectors. Futhermore, the stereo-mono signal also gives the speaker a sense of depth and imaging. Personally I love the effect and my buddy actually installed a few home theaters with the dual center as you described.
My buddy spoke to Billy Woodman, the president and chief designer of ATC about this. Billy completely agreed with the concept and did a lot of testing and measuring with it as well. In the end, the frequency cancelling as a result of the node intersection will degrade the sound quality too much to want to pursue.
This is a major reason why all center channel speakers, and speakers for that matter, only have 1 tweeter and 1 midrange. The new WEGG 3's from William Eggleston have 5 tweeters, but when you research more closely, there is 1 primary tweeter and the others are stepped futher away from the listener and play at lower decibles....
Cheers.
