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.

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).
