Hi everyone, first post here. I've been looking for a decent pair of Cornwalls and came across these locally and was hoping for some advice. They look like they have a few rough spots but overall not bad. He's asking $550. From my research they are built in 1981 and are most likely version 1 based on the appearance of the woofer mounting. I'm not sure about the drivers and which crossovers they have. Only thing that bothers me is that the serial number stickers look awfully new for 30 year old speakers, I'm sure I'm just being paranoid. Based on these pictures would this be a fair asking price? I appreciate everyones help.
