Default Older Speakers - can they be re-used?

Hi there,
I am new to the forum, and this is my first post, so please be gentle... :-)
I've recently picked up the guts from an old big Telefunken radio/phonograph console (I think it is Opus 7), including receiver, power supply and a 6 speakers... The radio itself is beyond restoration (that's what I do for a hobby), so I was thinking about selling it, but then another thought came to mind... I could re-use the electronic parts (power tranny, output trannies and four EL84s) to build a nice PP amp! I can do that, but I know very little about designing/building loudspeakers. So I am now looking for guidance on what to do about speakers. Can they be used to build a set of loudspeakers? I am attaching a couple of pics.
Any suggestions would be much appreciated.
Thanks, Paul

Certainly.

Can you post pictures of the backs. That should confirm that the ovals are isophon as is the tweeter. The tweeter looks to be one of the shallower ones, and likely aperiodic (it will have a pattern of holes with a piece of cloth covering from the inside).

These are fairly sought after, quite musical althou a bit coloured. Best used OB, or in a very big box.

My 1st successful eBay auction fetched $90+ for a set of those tweeters (now that people realize they aren't all that rare, maybe $40 if they indeed are the aperiodic shallow cone units)
