Anyone know what these funky vintage speaker are?

I just acquired a really funky looking set of speakers. I have no idea what they are except that they are vintage. No markings of the maker anywhere on the speaker. The only information I see on them is this: on the bottom of the woofers, one says Nordmende, the other says Made in Holland. It looks like it is a modified 9750M speaker and is marked 9750M. The capacitor is Sprague and looks like 1960's? It has a nice, unique sound quality to it.
Any help is greatly appreciated.
