Frankly, the numbers don't mean very much at all in the
real world, other than to a designer or manufacturer -
for example, the frequency range of a full orchestra is
only about 40-14k and the *dink dink* 'Top C' on a piano
is only about 4096 Hz with only weak (inaudible for most
purposes) harmonics extending beyond 10 kHz....

If the harmonics were inaudible it would sound like a
sine wave. So nothing like a piano at all.

I'm amazed at you. You go on and on about the subtle
differences you claim to hear then come up with rubbish
like this...

More to the point, is the lack of quality of reproduction that we get at
high frequencies by single-way drivers.

There are hard physical laws that say you can't have deep bass and high
efficiency and small size at the same time. If you add good dynamic range,
then things get that much more difficult.

In a similar fashion, you can't have deep bass, extended treble, smooth
response, and broad dispersion at the same time.

I still remember doing some frequency response measurements on a "full
range" JBL 15" driver in engineerings school in the middlee 1960s. Believe
it or not, it had response at 13 KHz. But only on-axis. And only after a
number of audible dips and peaks at lower frequencies.
