We'd have to be able to do that, because percussion instruments don't do continuous tone. And they all have their own characteristic timbre. Even cymbals of the same type & dimension, but of different make.
We really do pay far less attention to the continuous tones, for those instruments that do them.
Pianos for example don't do continuous tones, it's all attack and decay.
Of course pitch matters, 'If you can't pitch, you can't pitch'. It's how you start, no? Very big effect on what happens next, no?
Knowing this, we ought to require that audio reproduction systems should have matching rise and decay behaviour, and fast enough to boot, too few do. 'Stats do, and they engage with rooms less than other speakers.
The trouble with horns is the steep filters so many need between each driver. Some even need notch filters within their pass band, because they ring. So, their impulse and step response is poor compared to a FR 'stat.
I've heard quite a few 'good' horns including ones with Vitavox drivers and their speed is quite good, but their coherence can not match that of a QUAD FRED (the 63 and on).
My favourite horn was one of the bigger designs by 'Tommy Horning' with most of the range covered by a de-whizzerd Lowther driver. Plus deep bass and treble assistance. IIRC with minimal odd-order filters.
I've known Klipschorns and Lowther based horns since my twenties, I'm now 66. I used to work weekends in Canberra's oldest audio shop.
I find equal temperament eventually tiring, can you tell me why that might be?
I don't do willy waving, but I do like clear informed thinking.

Hi Tim, FR STATS share similar problems with so called FR cone speakers in that IM distortion is the dominating factor of distortion and its audible very much audible, you pick what you like and THATS that..
but IMO 8 way 13-80kc covers all the octaves with less distortion(including the terrible IM) then any STAT will now... Meet Fulton the ,Large premiere's only speaker that can play a grand piano like no other :)
now some people may disagree with me and that fine because there is no horn system, lowther, STAT, that will play like the real thing in your home like the large fulton system can.
high sensitivity does not mean hi fidelity.
Edit: for jeff :) a large fulton speaker with the "80 driver" for the mid-range will play and sound very similar like a real piano is what i mean to say organically
I have always thought that 63s and later small models need to be filtered and given subs. Between 100 and 150Hz. When you do that diaphragm excursion is quite limited.
Tom Danley (aka TomServo) agreed with my proposal following.
Ist order HP and 3rd order LP @ 150hz. Because using 4 monopole subs* in a swarm arc at the same listening distance. When the diaphragm excursion ceases to be a problem, and the room-gain totals relatively smooth at the listening seat. Lots of amplifier power needed for the bass.
That's what I am slowly building, on a limited monthly of <$ Au 400 budget. Dipole subs are way out of my budget.
* two large push-pull sealed subs as stands, and two tall EBS (Rb) subs to the inside of the QUADs corner edge on and 2nd HP filtered down below pedal reeds.
I'll use a bit of Eq if needs be, and later go with DSP as funds allow.
