Default Pyramid T-1 info wanted

I'm posting this question on other sites to maximize exposure about a probably little known speaker, the Pyramid T-1 ribbon tweeter. I've got a pair of these (serial nos. 0028 and 0041), but no manual or information of any kind. I'll take any info I can get, but most important would be appropriate amplification and suggested crossover frequency. Thanks for any help.

The best bet would be to contact Dick Sequerra. He made the ribbons. I do not know his contact info but try Googling him.

I guess I should've mentioned I emailed the "contact" at the Sequerra site. No reply. That would be the one and only avenue I could find for contacting Mr. Sequerra.

It looks like 1.8KHz is the minimum recommended crossover frequency (according to the product specifications):
