Quadral T55/10/XX1000 tweeters

I need data for Quadral T55 / 10 / XX1000 tweeters, impedance, sensitivity, frequency range recording, datasheet, anything. Or some link to some restoration, replacement and the like.

As far as I know, these tweeters were made by Technics. You can ask Quadral.

The speakers are not mine, I want to help a friend. The plan is to replace them with higher quality RAAL ribbons with a custom made frontplate to match the Quadral dimensions, as the existing ones are defective.
I know they look like some Technics models, but I'm not sure they were made by Technics.
I contacted Quadral a couple of days ago, no answer yet.

Originally Quadral often used Technics EAS-10TH400C and TH-800.

The problem was solved by installing RAAL ribon tweeters model 64-10 with a custom faceplate (8ohm impedance). The faceplate can be black or brushed stainless steel. These tweeters are of better quality than the original ones. The difference in sensitivity can be compensated by a series resistor (1.5-2.2 ohms).
