Greetings! I am seeking information on the various Altec 418 drivers that were made in the 1970's, since I want to try one out for use with guitar, and am trying to figure out which version to look for. I think I am trying to steer clear of the "H" version. In particular, I am looking at what seem to be some unusual examples that are currently for sale - they seem to be a 'hybrid' design in that they have the old 418B magnet cover with the long 'Ling/Altec' labels, but they have the heavy cast frames that look like the newere style 418-8H series II type speakers. The cone numbers are stamped "21353-4" - I have seen -3 numbers on 418B's but have not seen another case with the -4 version. Here is a link to the image:

If anyone has any information on these, or has definitive cone number charts for the various 418's, I would be most appreciative!

regards, Dave
