What is the effect like using just one speaker?
How big is your tweeter?
Have you looked at an analysis of directionality relating to
wavelength and driver size? There is a good one in Martin Colloms'
book 'High Performance Loudspeakers'.

Did it in my degree.

(Well, at least to 1st order, anyway.) Forgotten the formulae now,
but not the basic concepts.

The tweeters are average size; a bit less than 1 inch diameter.

Must admit, don't have the book but have obviously heard of MC. Used to do
measurements for "Hi-Fi Choice" too, didn't he? I think that's where I
first encountered his name in the late 80s.
