Altec 605A duplex help

[JUGGERNAUTAUDIO]

Hi, im new to the forum. How is everybody?? Well i purchased a pair of altec lansing 605A duplex speakers the other day. I have been looking all over for some info on the peticular pair i have. The pair i have the red surrounds, witch i have heard are the older first series. The question i have is the crossovers are n-1600c and say 16 ohm, but when i ohm out the HF on the speaker they read 5.0 ohm. I thought the 605A's were 16 ohm speakers?? The LF is reading 11.1 ohm, so i know thats a 16 ohm diphram. I did take the HF cap off and looked at the diphram it has the Ll on the black plastic surround of the diphram. So has someone changed them or is it original? they look as no one ever touched them..any info on these speakers would be great.. Im adding some pictures, i also wanted to know if the red paint on the HF screw is some sort of tamper seal?? Thanks for all your help..

Hello,

I think your 605a with red surrounds are reconed. Maybe they have a new HF diaphragm as well? I have 3 605a and one was reconed long ago with the same red surround.

Juggernaut, those red surrounds are typical of 605B drivers, but I'm not sure whether Altec switched to those surrounds before beginning 605B production.

The red paint is original, a tamper seal as you suspected. The stamping of "L1" on the diaphragm ring is typical of Altec diaphragms, so I would suspect that your diaphragms are original. Nice drivers.
