Identify 414 Woofer

[zeez]

Can some tell me best way to identify a pair
of 414s? Advertized as 414Z when I bought them from Ebay but are neither gold nor green and no
Altec 'tag'. Black frame- I'm guessing
414-8A,B- any definitve way to know?
I've checked Altec catalogs,specs,plans- missed it? Maybe. Thanks much.

Hi, zeez,

A 414Z should have a 21066 cone, and possibly the number 105280 stamped on the magnet or frame. An 8A or 8B would have an identifying decal.
