Hi Ive just picked up a pair of 2ax speakers for a pittance and with a few turns of the pots all the units seem to work fine. I was going to use the tweeters for restoring a pair of 5s but they seem to good to break up. I think they are quite old as they have an 11 in woofer with a cloth surround The serial numbers are 99662 and 99965 and I was wondering if the big gap between the numbers meant they weren't an original pair ? Also the veneer on the top is quite a few shade lighter on one than
