Selling, donating or giving away a good pair of vintage speakers

If I was in driving distance to you, I would surely take them off your hands. I would rebuild the crossovers, eliminate the toggle switches and find use for them in a 2nd, or 3rd system. Beautiful cabinetry. I lived with a pair for a while (on loan from the rep firm that handled Koss at the time) and thought they were enjoyable. My best, MrD.

Take a few photos and put them on CraigsList for $400-$500 for the pair.

List it for free on a local facebook audio enthusiasts group. Some young lad/lass who’s broke as a joke, but, loves music will pick it up and should (hopefully) have some fun with it.

If you put it on facebook marketplace, some regular utilitarian creature with no interest in music will pick it up and immediately resell/try to make a buck off of it.

On second thought... and sorry to be blunt, but, those speakers look like they are poorly designed (to begin with) and probably sound bad, i.e., a poor design coupled with 40 years of degradation. So, maybe, FB marketplace is fine for this speaker too.

If i were donating stuff that’s competent and sounds good (worthwhile), i will list it for free on the enthusiast groups and hope it reaches someone capable of enjoying it.

Since you live in the SF area, put them on the street, and someone will have a second bedroom by evening.

If you can afford Magico's, you should give them away.  Most of my friends don't have anything that good and would love them.  One uses a Bose TV soundbar, etc.
