Does anyone recognize these drivers?

I found these homemade speakers for sale locally to me here in Finland, they are pretty cheap and i am looking for some 8" midrange speakers.

Seller does't know anything about these. Those cabinets are 10" wide, so that larger speaker must be about 8". It looks like visaton b200, but its a bit different. This has 8 mounting holes as visaton b200 has only 6.

Do you recognize these midrange or woofer drivers?

Here are 2 pictures i got of them. Imgur: The magic of the Internet
 
No idea what those drivers are but certainly a high efficiency woofer with a corrugated surround. Tweeter looks like a standard 1" type around 100-104mm faceplate. Looks a bit home-made...

Bit like these Sony E44 I played around with:

Crossovers can usually be improved. This works:

This sort of thing is better:

I'd be most interested if there is room below that 4" "reflex" cutout for a tweeter, being a tower design. Turn it upside down and you might have a cabinet suitable for a three way:

Worth about 20 Euros as a fun project IMO. I suppose you must factor in the cost of collection.
