You are bidding on a pair of 7 by 4 inch oval speakers that were removed from a European tube type tape recorder.  The cones are excellent with no tears.  The voice coils are good, and are 4 ohms.  These have Alnico permanent magnets.  I believe this is an unusual size.  The code marked on them is 619-4, but I am unable to determine the manufacturer.  These are nice quality speakers that should be great for your project.  Shipping weight is 3 pounds.  Please see my other auctions for more interesting radio and audio items and tubes.
