Hello Charles ! Welcome to the board ! Hope you find all the info you need to help keep those nice drivers still thumping.I agree with going to GPA for all your Altec parts and repairs.Stay away from after market stuff on eBay and the like.IMHO you will be just throwing good money after BAD !!!.Bill makes some very nice replacement diaphragms.They are considered Altec factory replacements.He bought all the tooling from the Altec plant when they closed

FWIW, i have series III cones in my 604-8G's, i think they're lighter/faster than originals.

My 604-8G's still have their pristine 23739-4 cones in them.That sound real nice.Fast, but not as fast as a 416 me thinks.Now with Bills cones/#'s I'm not as familiar with the different cones he has except for the 416's I had re-coned that sound great.So I don't understand some of the folks who don't like the new cones from GPA.I tried to A/B them with my M19 416's and I think the re-mag/re-cones sound a little better actually.But it was very hard to even distinguish a difference IMO.
