Two 602A and two 602D
Four drivers in all.
All tested and all sound excellent.
Three are freshly reconed and have no horn mounted as you can see. I do have the 3 horns and 4 replacement tweeters you can have installed.
They are not original tweeters, they are the proper replacements
One shown with the horn is original and works.
The woofers are basically 803s or 416s from all info available
I will sell in sets.
The one with the horn and its match and crossovers, 800, the other two with the parts for them 700
Two N3000A for the 602a and Two N3000E for the 602d crossovers and all the horn parts with new tweeter drivers.
Both sets crossover at 3000 cps
Here is some info

Altec model 416 factory cone, this is equal to an Altec Lansing model 803 or a 416, 15 inch woofer, (this is a 602A duplex
the altec 602 is basically a model 803 or 416 woofer with a concentrically mounted model 3000 horn tweeter.
die cast aluminum basket, 'AlNiCo 5' (aluminum, nickel, cobalt) magnet, is rated to have a fequency response of 20-1.6kHz, 3 inch edge-wound copper ribbon voice coil, rated at 30 watts, and at over 99 dB sensitivity (@1w-1m).
10 watts in this speaker sounds very loud and clear
altec lansing 602A duplex loudspeaker, used the same basket and motor, with the model 803, or 416A and others..
Read at the 'Lansing Heritage' site, that the Altec factory never rebuilt the high frequency horn tweeters in the 602 duplex, and were replaced instead of repaired.
this woofer will be a great fit in; a profesional monitor or home vintage hi-fi speaker with a nice full sound. these paired up very nice with large 500Hz or 800Hz hf horns as in; the "magnificent", and the 'voice of the theater' horn loaded bass reflex cabinets, or the big professional 612 studio monitors, or home hi-fi 'valencia', and many others
