Bill,
You definitely bring up a interesting dilemma. I too have tried using some different horns/drivers with my 4 Pi pro's(as long as I have a JBL 2226 in the house-I have a 4 Pi to be able to use!)

Right now there is a ALtec 806-8A on a 811B horn with EV T-35 tweeter. I am using 15 ohm parallel with 25 ohm series(bypassed with .33 ufd cap) and then running through a L-pad.

The T-35 is using a .5 ufd oil cap with shunt .5 mh coil and L-pad also.

If the tweeter level is to high, the mid horns sound too screechy and if the mid horns are to high, then the sound is shouty.

Trying to add a powered sub in the mix adds more phase issues.

The reason for the L-pads is so I can swap compression drivers and horns quickly.

Ron
