Vintage NOS Altec 511B Horn from a Live Sound Co. Inventory. Some would say that the Altec horns, i.e., the 811B and 511B, are unfit for listening and are better served as funnels for draining oil from semi trucks or, worse yet, poor urinals… If ever you compared an 811B to a 511B in a back to back comparison; most and, I would agree…with respect to the former.
