Seem pretty good, what do you think? Those are little dust prints at the bottom of the cone, not sure what those tear drop looking things are. Any harm in carefully taking a soft cloth to the cones to clear the dust?
I'm no expert but I'd probably use a microfibre cloth, just avoid the cap in the center of the speakers, they can dent real easily. They look to be in great shape though.
I think it's just glue from the mfg.
Definitely real wood. Unclear on manufacture location, though it has the California location on there
Pretty safe bet MIU circa 1985
