need help on info on DUAL type 260283 10" Full Range Coaxial (german made)

Hello everyone. Would like to seek your help regarding these pair of DUAL type 260283 10" Full Range Coaxial speakers. Don't have much information on these but would apreciate if you can shed some light on this pair. A friend of mine is sending it over and will be arriving in a couple of weeks. They're made in germany. Impedance is 4ohms. That about all the info I got. Maybe some of you have come across it and can share some experiences with it.

What kind of amp would best suit this? SS, tube set or push pull?
What kind of baffle would be best for this?

Any help would be greatly appreciated.

Thanks,
earl

I am not that sure but as far as I remember these weren't coaxials but woofers with an odd looking "phase-plug". AFAIR the boxes they were used in had a tweeter as well.

The drivers themselves could have been made by the German manufacturer WHD.

Apart from that there is a Dual board in Germany:

Maybe they know more.
