Which commercial super-tweeter should I consider for maximum treble
with maximum SPL?

Default High SPL Treble

The old EV T350 is considered by many to be the best tweeter ever made. I have
a pair and I love them. They have big magnets and they are super efficient.They
can be too hot for some systems and will require an L-Pad or resistor to cut
them back. Problem is that their reputation has caused them to sell for up to
$900 a pair on E-Bay. The newer versions, ST350, sell for less because they
aren't "vintage" and they probably aren't quite as good. The EV T35's are OK
but have less output than the T350's. The old Altec 3000's and University
HF206's are nice and pretty efficient too, but they won't give as much SPL as
the T350's. For new tweeters, maybe TAD or Fostex?

What is the frequency response


Unlinear.


What is the the highest frequency it can play?

At what conversion efficiency? - loudspeaker units generally have their
usable frequency response within a 10 dB "frame", but they don't just
stop doing sound as they "leave their specs". Consequently when asked in
an undefined kind of way the question gets meaningless. We are however
talking about a horn driver, and it is unlikely to have usable response
for more than 4 octaves, and to get maximum efficiency in the audible
treble some of that response could be "sold off" by moving the resonance
of the front chamber into the audible range. If so - and please
understand that no claim of technical accuracy is made, this is
explained in an illustrative way - then it is likely that its _useful
response_ would end no higher than 24 kHz.

No absolute statement of any kind is made in this post, the actual specs
of whatever treble driver this was about are unknown to me.

If you by "super-tweeter" mean drivers that extend beyond 20 kHz, there
are very few to choose among. How about the SA 8535, also known as the
Ribbon Compact Driver ?
