Coral Audio STAGE 3 speakers

Hallo, everybody,

I have recently found a pair of those VERY rare enclosures (though without front grills). It is a three-way system, with particular propeller-shaped tweeter and medium metal protections. Can someone tell me more about those speakers, as the Internet is rather mute on the subject (as it is for the company itself), apart from some pics ? Thanx in advance and greetings from merry Belgium !
