Hi,

What is the throat angle of the JMLC horns? I have not been able to find the information anywhere.

Thanks,
Jeppe

Hi Jzagaja,

Thanks for posting! Is that a BMS 4592N used as a compression driver in the Black Swan, and do you know the crossover point between the compression driver and the woofer? Thanks!

Best regards
Peter
