Yep, but I really don't know what the upper limit requirements might
be - if you do, post them here. Meanwhile, here's some more interesting
figures that show the FR range of various instruments isn't as wide as
we might think it to be:

All of which point to a need for a 'decent midrange' (the OP's original
concern) in my book, rather than the speaker's ability to attract
bats...


Keith - again you are ignoring the fact that those tables refer to the
fundamentals. This is fine if you want your high notes to sound like sine
waves but you won't be able to tell what sort of instrument you are
listening to without higher harmonics.

I find that cymbals are the most difficult instrument to reproduce
electronically - they produce frequencies far higher than we can hear. In
my younger days I used to find the 19kHz pilot tone annoying on some mono
radios that didn't filter it out so, if you want something that sounds
right to a young person, you need accurate high frequency response to
greater than 19kHz.
