I've got a mint '73 Fender SFPR that was re-capped a couple of years ago after many years in storage. It had a cheapo replacement speaker in it from the original owner when I bought it back in the '70s. I put a Weber Signature in it when the re-cap was completed and it sounds pretty good. Is there a speaker that you guys would recommend that would be significantly better than the Weber Sig? Like soooo much better it's a no-brainer upgrade, or should I just stick with the Sig??
