The more you choose a narrow angle, the more its size becomes a limitation. You will end up with narrow highs and wide upper mids. For this reason a short vertical will overtake a wider horizontal and flip the pattern.

I'm not suggesting you use something like the Dayton I showed above, but understand, that it makes best use of the space it takes up and It doesn't try to start holding a directivity that it can't finish. Instead it hands off continuously within its limits.

May I request a bit of a clarification? Im not sure I can decrypt your post :S

I had to re-read a few times as well to decrypt it.

What he basically wants to say is that horns with a narrow radiation angle do often have small dimensions in the direction where their radiation angle is (intended to be) narrow - which in turn is detrimental to being able to actually control the radiation at lower frequencies. Which can lead to very narrow radiation up high and wide radiation at medium frequencies of the completed speaker. And it is also the reason for the pattern flip where a 90 x 45 degrees horn for instance has a wider radiation in the 45 degrees direction than in the 90 degrees direction at the lower end of its working range.

Does someone have basic ZMA etc files for 2226h that I can use (without measuring my actual unit) to test a couple of XO designs?
Thanks
