I have a sturdy black pair of Altec 511B horns that are surplus to my needs and for which I'd like to find a new home. No drivers are included; these are designed for 1", two-bolt compression drivers.
One horn is in very good condition; the other has been repainted and has two broken mounting "ears", so I'll call the condition of the pair "fair" on the average. See photos for condition. I have one original box, as well. Box condition is likewise fair.
Local pickup is HIGHLY PREFERRED. I am in the Connecticut River "Upper Valley" region, near Hanover, New Hampshire. The horns aren't heavy (about 18 lbs each) but the large box size would make shipping too expensive to be cost effective to most locations.
