I'm planning on building a plane array in a 4 way design. There will be four tweeters configured in a square so that CTC is less than .84 inches. There will be four 3.5 inch mids configured in a square so that the ctc will be 4.5 inches. It also has one(maybe 2) 8 inch woofers, and 1 12 inch sub woofer(in each channel). Comb filter distortion stays under one wavelength due to the closeness of the CTC and the crossover frequencies.
I have been told that the midrange horizontal disperson will be cut in half and for that reason I should not put them together like this. However my listening area is about 13 feet from the speakers in a sweet spot of 4 feet horizontal(couch). My online dispersion calculator says that the horizontal dispersion of the speakers individually is 38 feet at 13 feet listening. So cutting that in half is 19 feet. Even if I don't angle the speakers, it would seem that for me, in my listening environment, horizontal dispersion is a non-issue. The same exists for vertical since I am listening to the mids and tweets at ear level. I simply don't care about precision in other listening places or heights.
While for another environment this could easily be a problem, I don't see it as one for me in my listening environment.
Am I missing something important here?
