Altec Lansing 288B - Vintage Compression Driver Pair - Details In Listing

Description

Up for sale, a pair of vintage Altec Lansing 288B horn compression drivers.  These show a fair amount of cosmetic wear and paint loss, see pics.  They appear complete with likely usable diaphragms, the impedance measurements are shown.  I don't have any manner of testing in a real-world audio setting.  Please note: the diaphragms have a plastic surround which are different in these, I'm guessing this may indicate different years of manufacture.  Please see pics and ask any pertinent questions.
Note: one of the binding posts had unscrewed from the insulated screw and I had to put it back in place.  You may have to fiddle with this to secure it well and be able to use the speaker tap as intended.
The pair, despite there modest size weigh just shy of 50 pounds packed.
US bidders/buyers only please.  This will ship tracked and insured.
