Hi Paul
I have written some clearifications in Mr steadys post.
My first goal was to eliminate the exit angle missmatch between a 10.4 degree driver exit to a 4 degree horn throat (both 2" in diameter)

I figure I could do this by extending the horn curvature 107 mm in length, and letting the horn pass the driver exit, going inside the driver.

Secondly I figure, why sattle with an 107 mm extension?
Would it be of any gain indreasing this to (lets say 200-300mm) in terms of distorsion of cutoff?


Data:
The horns are 200 Hz cutoff tractrix (approx 600 i length and diamter). The horn throat are 2"

The Radian 750Pb is a 2" exit driver with 10.4 degree exit angle (about 1" Deep). It has a 3" voice coil

I am currently using a single serial cap making a very shallow x-over point at 350Hz. This was chosen by hearing rather than measuring. I have tryed several passive and active x-over configurations, but also digital (MiniDSP) -variants. But simple filters sounds best in my ears.
