Well, thank you for that exacting primer on how tweeters work. It was
very
informative. But it would have served this discussion better to explain to
us
what the mechanism is that keeps even the finest speakers from being able
to
convincingly reproduce trumpets and some other instruments.

Short answer - there are two rooms are involved and they create the
sticking
point.
When you reproduce a recording of a horn or other musical instrument, you
don't reproduce the horn, you try to reproduce it and its effects of the
room it is in.

The exception would be a recording of a horn that was made in an anechoic
chamber, the recording then played in an anechoic chamber. Those can be
made
to work fairly well and realistically, but of course nobody is interested
in
that.

The horn does not just create a sound vector (intensity versus time) but
instead it creates a sound field (which may be represented by an infinitude
of vectors).

The speaker does not create just the sound of the horn, but it stimulates
the room to make a bunch of other sounds. So there are infinity times
infinity other variables, and fools that we are, we try to send them from
place to place using a small number of signals.

Sorry, I don't buy that. Were that the case, one would think that at least
some rooms would make these instruments sound more realistic than in others.
Sometimes trumpets are close-miked in a studio and room interaction on the
capture side is nil. They still don't sound like live trumpets. But live
trumpets sound like live trumpets in any venue, any room, even outdoors.

My kid used to play a small drum kit in my listening room. I've
never heard my system (or any other) able to reproduce that sound of a
snare drum in my room and for that...I am thankful.

I certainly understand that, but a drum kit - in the context of the
music using it adds quite a bit. It would be nice to be able to
reproduce those drums accurately, Not the kit playing in your
listening room (by your kid), but playing in the venue in which the
whole ensemble was recorded and bring THAT into your listening room.
Drum whacks, pistols firing, these are more things that simply cannot
be accurately reproduced by modern technology.

Like I said to the previous poster. Trumpets (and drum kits) sound
from speakers are not real sounding, because technology can't do
that...yet. Make no mistake, the previous poster's allegation that
it's the two rooms involved that make trumpets (and drums among other
musical instruments) not sound real holds no water. because these
instruments heard LIVE always sound right, no matter where they are
heard.
