"The reflex driver is XO at 175 Hz to the mid-horn. Again the integration with the whole seems pretty good, but not as good as with the mid and top horns."
I don't know if you can do it on your x-over or not, but try delaying the reflex-driver to match the depth of the mid/hi horns and see what happens. If not you may have to play around with x-over freq. between the reflex and the mid-horn. HTH Bill W.

Wavelength at the 175Hz crossover frequency is 6.5 feet. That gives a window of about a foot and a half to two feet to stay within 90o to 120o. The crossover will also introduce phase, but the point is that we're talking about critical distances of about a foot or two. If the depth is a foot, I'm pretty sure Charlie would find he's within a quarter-wavelenth or 90o. If the distance is greater, then there may be reason to do some measurements and/or calculations to find out if the phase difference exceeds 120o. That represents a third-wavelenth, where we start seeing the edge of nulls begin to develop.
