Wayne- I have some Q's about your passive x-over(s), if you don't mind.
1.) Do you sell them as a separate component?
2.) How many variations of your 1.6kHz x-over exist? That is, do you have modifications for different driver options (Eminence, B&C, JBL, etc.)? Here, I'm thinking about your Midhorn/HF combo.
3.) Since the HF driver is set forward of the Midhorn driver, how does the x-over compensate for this offset? Here, I'm again thinking about the coaxial variation of mounting an HF horn in the mouth of the Midhorn. (Yup, this mod still appeals to me!)
Happy Holidays to all!

The crossovers are available separately for $99.00 each. They are optimized for the application, and so aren't always suitable for general purpose. The positions of midhorn and tweeter are important for summing to be right.

My intent for the crossover would be your existing midhorn/HF application, and not for GP. I was simply wondering if the HF horn's frontal position (above, below, either side, or inside) were important as long as the depth ratio between drivers were preserved? (I already had some intuition that summing was involved.) And, if another compression driver were used (like a B&C, for instance), might any conjugate or compensative filters differ?

Yes, the wavelenths at crossover and driver position are calculated to ensure proper summing. Measurements prove each driver is exactly where it needs to be for summing to be right through the overlap band. Compression drivers act pretty similarly at low frequencies (where crossover is made) so no changes are required when substituting drivers.
