I am curious about the tweeters used in your Gamechangers. In the CBT36, a point is made that the very small, closely spaced tweeters help to avoid comb filtering below about 15K. The tweeters used in the Gamechangers are larger (1" domes?) and more widely spaced. Theoretically, shouldn't that affect the sound quality? Any noticeable effect?
The reason I am asking is that I am considering using 84 1/2" Parts Express tweeters used in the CBT36 as a tweeter line next to a BG RD75.
