Someone was asking about supertweeters recently, and this evening someone
brought over a Ying Tai mode LCY-100K supertweeter, which he had purchased
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.
