Altec PA Columns, What Woofers Were Used?

[toddalin]

There is a pair of Altec PA columns nearby that seem reasonable in $$$. I remember these column speakers (similar to the Shure Vocal Master but way nicer) and was wondering what woofers were used (size and model) (8", 10" or ???")

The seller doesn't list a part # and the Altec site lists all vintage products by number.

Anyone with any ideas?

Thanks

Thanks, I guess they used the 403s in several of these columns. I didn't realize they used such "poor" components in these.
