Someone was asking about supertweeters recently, and this evening someone

from e-speakers.com. It's some sort of tiny ribbon with a very high resonant
point, intended for crossover at 10 or 13 KC with an internal 18 dB/octave
high-pass.

I found that it made for a lot more top end on my Maggies, but since the
speaker had no low-pass network on it (and it dropped off only at 16 KC),
setting it to 13 KC still produced a high frequency bump that was audible.
So I don't know what it would do on a system designed for it.

Wouldn't an active crossover allow answering the question?

Maybe, but then I'd have some unfamiliar electronics in the signal path
as well.

If it's a ribbon with a "high resonance point" that sounds
like it'd be bumpy, anyway.

It is, but it's just one bump, and it's a really high and really wide
one. The low slope helps a lot.
