I've gone down a rabbit hole lately after learning about the Ikonoklast Tweeters. I have a rebuilt pair of the Infinity Walsh tweeters that I want to use in a 2 way Omnipole design. I found various posts about the old Walsh tweeters on this site and others describing their sound and how to rebuild them so I bought a pair needing TLC on EBAY and did just that. These Walsh tweeters are perfect, after all, with their 360 degree dispersion, for an Omni-pole. They are very fragile though and I am not sure exactly how to add them into a 2 way? So then, doing a bit of research, I saw the Ikonoklast version, that I believe are based on the Morotola powerline series 1141a. They are very sturdy, and go nicely down to 1800hz easy to XO, add an LPAD etc... I am thinking about building a pair into infinity style Walsh, then seeing how they go. Should sound very very good. The Ikonoklast speakers have very good reviews, especially their tweeters. There are plenty of threads 'out there' on how to properly use piezo tweeters that don't discuss the Walsh style at all, but can give good guidance on how to get great sound and overall performance out of them.
I will be using the SS 15w8351k00 firing directly up into an acoustic lense. That driver will receive a 2nd order XO to roll off around 2k. The Piezo Walsh will get a 1st order cap in series which will give it a similar XO point. According to Ikonoklast this is fine for this piezo. I don't think it would have been as easy to get the Infinity walsh to cross that low. And I really don't want to cross the 15w higher.
I will use .0002 mil hard Alumium foil backed by packaging tape(Mylar). I found the Walsh cone template out on one of the diy sites. I will then glue it to shape and then glue it to the piezo element. I don't know exactly how the Ikonoklast tweets are built, so I have to go with how the infinity Walsh rebuilders do it.
I will probably test my speakers, when they are finished, with my rebuilt Infinity walsh tweeters just to make sure they work, then I will sell them on Ebay if I can get the piezo walsh version to work.
Anyway, anyone wanting to try an exotic tweet in a two way can maybe experiment with something like this. Or anyone wanting to build some cheaply for an old set of Infinitys. The Infinity Walsh tweeters are hard to find in working order.

Pictures please? I just got my first piezo, actually Peavey double-piezo MEH. Your project sounds very interesting.
This "exotics" forum looks far, far off the beaten path. I've been posting omni/LX/etc experiments to the "fullrange" photo gallery... including half-space hemispherically omni-directional multi-tweeter reflector. Perhaps piezo ring?

Just out of interest, do you know the used frequency range of the original Infinity Walsh tweeters?
There were 2 early Infinity designs which used the walsh as a full on tweeter from ~ 5khz on up. You'd need to do a deep dive on finding those speakers schematics to see exactly what those XOs looked like. I do think bringing in the walsh as a 1st order is pretty simple.
As far as pics? I m still getting all the parts. Almost there and should begin building soon.
