They look in great shape.
Very easy to change the cloth, simply staples on the back of the grille's wood frame which simply pulls off push-on retainers. I used white Irish Linen.
The old way of testing speaker cloth was to see how easy it was to blow cigarette smoke thru. (In a corner, it could stain the fabric as well as your lungs).
I would have the dealer confirm the 12" woofers are the original dual coil ones.
As I said, a new select veneer would improve their appearance quite a bit, in which case the appearance/condition of the original veneer is unimportant.
If the tweeters are blown, if it keeps the price down, that’s a good thing, put JS recommended SEAS ones in! These already have the SEAS tweeters.
