I recently found this forum and thought I'd share these pics of my Heathkit AS-21s with you. I just got them from the gentleman who purchased them new.
The drivers are Altec 806A w/811(?) horns and a pair of 414A woofers in each cabinet.
I don't know much about the history of the speakers, their original cost or whether these would've been sold new in kit form or not. Any further information would be greatly appreciated!! Also interested in purchasing any original literature for them.
Thanks for looking.
