Help with Motorola Horn tweeter

[dimkasta]

A good friend of mine found these little buggers in his stash.

He bought them at around 1990 after ready some raving reviews about them, but he cannot remember any specs for them.
We tried them as a super tweeters on his Tannoy GRF Memory with amazing results.
What I am looking for is any info on them that might help us cross/protect them properly.
Oh and any suggestions for mounting it on a baffle or something are more than welcome 🙂

Thanks in advance

The truth is almost any of the piezo elements from any lens will work there, there are some of better quality, but not much. Piezos much maligned for not very good reasons when used in this range.

Piezos do vhf very, well mate well with 6" drivers.
