my roughly 20 years old genelec s30 are specified to go to >25khz,
mundorf amt tweeters go up to 41khz, adam s4x-h are specified do go up
to 50khz.
the mundorf amt's can be used for PA speakers, a college of mine once
used them to build a line array

but of course you need to distinguish between distribution and
production, were you can benefit from frequency headroom.
