Bought a new house and bought Bill Waslo's Cosyne speakers. So listening to those now.

Before I trashed my little array, I ran some measurements of it. In one case, I measured it shaded, and in another, I measured it as a Bessel array:

Here's a couple of measurements of a five element array of 2" BMRs. The first is wired as a Bessel. The second is shaded. As you can see, not a huge difference. At 200Hz, the Bessel array is 3dB quieter, due to the weird Bessel wiring. (In a Bessel array, one of five elements is out-of-phase.)

Note that you still lose a lot of high frequency output in an array, which is why commercial arrays use a LOT of tweeters. Even with 10dB of boost on this array, the output at 20khz is still drooping about 10dB. Arrays need a lot of EQ.
