BoringSounds

Dear All,
  Its my first post here, actually the reason why I signed up.

I just came into the possession of a pair of AR-7s, they seem to be in reasonable condition, the cases only have a couple of scratches and the grilles are clean, they only have one tarnished brass? logo..
I have a couple of questions, I would like to know:

Are these the original tweeters?
Is it expensive for both bass units need to be refoamed? Are there any differences in the kits that you see online? Which ones are the better ones? etc
Are they worth refurbishing?

I would like to have some bookshelf speakers for the library (small box room) powered by some old naim gear (nac42.5/nap110/snaps), until I build something better..
Would these be worth the work?

Sorry for all the questions..

Thanks

David
