I have a pair of EJMLC 300 horns driven with JBL 2450s crossing to a beyma slot tweeter at 8000hz but I have never really liked the top end.
I was wondering how high I could drive the horns with an alternative possibly Beryllium driver/ Yes I might need an additional extension.
Eliminating the tweeter would solve the problem of comb filtering.

The horn can run as high as you like, 20 kHz is possible with heavy equalization by a DSP. The top end will beam though, the beam width gradually decreases from 150 degrees at 1 kHz to 40 degrees at 10-20 kHz.
The JBL 2450 driver has usable output up to 18 kHz. From 8 kHz onwards, a lot of resonances are going on, but it might sound okay if enough equalization is applied to tame the main offending peaks.

Thanks yes I looked at the graphs to choose my crossover point its very linear up to 8000hz. I am having trouble solving the combing problem and was wondering if something like the BG RD 50s would solve the problem or adding changing to a JBL 435BE with the appropriate horn extension. As it is the horn sound very good very linear output with no other modifications.
