Identifying Altec originals

[Bonzo75]

Thanks guys.

I am seeing a pair where the impedance rating for one driver says 11.01 and other is a 12.42. So that's best avoided?

The other pair has these non Altec binding posts. I assume that means the driver has been tampered with, and there is no point trying to plug in the Altec binding posts?

Thanks

Small variations are normal. Those are OK for 16 Ohm drivers.

The pictured binding-posts were certainly used by Altec on the 288-291G + H series drivers , as well as the first few runs of their ferrite-magnet replacements ( 288K-291K series ).


For some reason ( I suppose early am lack of caffeine , etc. ) I assumed this thread was specifically about the small format 1" exit drivers ( but after rereading the opening post I see there's no explicit mention of the smaller drivers ).

My bad!
