This goes back a long time, but if I remember correctly, H H Scott had something like that, Then KLH and Infinity. Maybe others now too. I doubt any of this would help you id yours.
I wounder how the efficiency level will work out.

...just thinking out loud...
I don't know what the brand are of these ribbon tweeters...ha!
So if anyone knows...help me remember!
Anyway I've purposely stayed away from any kind of super tweeters
until a few days ago...I've been slow to walk this path...as I very carefully added one component at a time and
I learned a great deal...so finally decided I don't have the money yet for the Fostex amk mk2 or whatever they're
named...but I had these, an extra behringer and a fairly decent yamaha amplifier(p2075c). Fortunately I also have
an s/pdif to 3 aes/ebu box so I thought why not!
First, this is going to be a long battle...I'm not kidding myself(disclaimer).
But the potential benefit is very clear.
Low, lows...mid bass punch...mid range clarity and now...beautiful air!
The XO point is 10.1kHz....and to start...and maybe this is not the best starting point, but I've got both the
mid range and tweeter with 18dB butterworth. Kind of afraid of overlap until I get them properly aligned...mebbe..I dunno...
One big difference that popped out is that the mid range changed.
I haven't exactly figured it out but the sibilance of a voice or crack of a drum..more information. But is there something psychological?
I fear the 4 way...but it's irresistible and what was a beautiful sounding stereo sounds stunning... Oh...I still need the proper foam
surround for the mid range horns which is what I will probably do next. I STILL am not happy with the ideas I have had so far.
My feeling is that done properly...tweeters are good.
Actually I have one EV-T350a somewhere so if one of you guys have an extra one...well I want it!

Your neighbors called. They like your music.
The efficiency is not an issue with a dedicated power amp.
Yeah thanks...there are no markings whatsoever of any distinction...so will need to research it.
My ears are feeling the power of the dark side...Feel the power of the dark side Luke...
5 hours of listening and tweaking last night...peddled through snippets of more than 200 songs...
Pretty much the same size...but I dunno.
I will say one advantage of the super tweeter...and maybe because I'm pretty sensitive to
the frequencies up there...but the only major battle without the tweeters was trying to
get enough sparkle from the GPA288H and I'm a little down on EQ...but even with it...
the sparkle and "spray" are not happening. Still the 288H has got more sparkle than the modded 808a's. I sense I'm in for a lot of work here...
But the problem was pushing the 288 too much. Now I can move the 288Hs volume back a little...and still keep the sparkle above.
What are the bass bins? and what woofs?
They are quite impressive.

Bass bins are actually are a pair of the original BASSMAXX prototypes,
somewhat similar in design to the ash6118? jbl horns. The woofers are jbl 2242Hs.
A link to the restoration process of the cabs can be found here...I did this while in Texas:

On the 288 experimentation side, you might check out the modules in this thread if not familiar:

Of course, perhaps already trumped by seperate amplification with EQ.
I tried the 30923 and the effects are noticable, I'd like to get fresh diaphragms on mine (288-8k) before passing judgement though.
I don't expect my 288's to compete with the extention of ribbons.
In my case I was going passive, and even the Aurum Cantus' didn't keep up with the 288's well enough to be used without attenuating the 288's.
* edit: On the 'spray' side of things. Try a MR horn?
