RE: Help needed with BMS compression driver horn experiment

hi Kurt

i do not experience any harshness with my orphean horns, at any db level.
What i am more and more convinced is, that the Orphean is a highly compromised design.
1. It's beaming in the high frequencies, and this can be clearly heard, and it's disturbing. To use a fostex tweeter above 5 - 7 khz probably would give more satisfiying results.
2. As Jean Michel LeCleac'h explains, a driver in a 250hz horn should not start to operate lower than 1 octave higher. So a better cut off frequency for the bms in the orphean horn would be 500hz.

The best would be probably use a bigger horn, like the Jabo75, and high-pass at 300hz, and use a fostex tweeter.

Honestly saiyng, i suspect other drivers are better than the BMS; soon i will try out the Radian 950 pb.
