More like the only advantage the Beyma has is the price.

A local speaker company gave a presentation about a year ago on their
development of new horn profiles for cinema installations. They used Beyma
comp drivers and detailed all the problems they had detecting the cause of
resonances. Turned out to be air leaks from the compression chambers, or
'false' sub-chambers within the compression chamber arising from poor
casting technique.
No comment on JBL, but Beyma are 'cheap clones' and the above experience
suggests consistency from sample to sample may be unreliable compared to
JBL.
