Sansui s-4900 speakers?!

[Alienz]

Hi,
I just picked up a pair of sansui s-4900 speakers at gw store for 3euros/4$. Has anyone ever seen these before? I cant find any info on them. They are 6 ohm and look very cheaply made, still it has the name sansui on it, they look like they belonged to a set?

I hooked them up to 2 different amps this evening, as expected very 'boxy' sounding in the low end but in the high end surprisingly clear and detailed compared to how they look
They'll do just fine as some testspeakers on my workbench.

Still wonder if they were part of a sansui 'all in one' set, did they ever do such a series?
