Identify Altec 414 Woofer

[mgzny]

Would like to know best way to determine model of 414 woofer pair.
No Altec 'tag' present, no magnet cover, neither gold nor green.
Black frames. Advertised as 414Z when purchased- just not sure.
Any clues appreciated.

Hi,

Model 414 Z is a production series used for home system cabinets no need for cover since it was sold with cabinet and nobody would look inside to see it.

Here is a site with some info on 414A. Early model.
