No writings at all ??
Post some pictures, who knows, somebody might recognise them.

Having problems loading pics on this forum. I will email Chris the pics and ask him if he can load them. No markings on speakers at all hence the

question.

Any idea what they are? Anyone?

I don't know them but they do not seem to be studio monitors.. only home speakers..

I had a friend who had a pair of those a long time ago, but I can't remember anything about the model number. They were 25W - 30W hi-fi speakers, not monitors, and middle-of-the range at best.
