Not from that distance and photo size. Could be anything, but to me they look like standard issue, 60's era replacement speakers, four 8" with either a 3.5 or 4" being used for the tweeter. Really need the manufacturing EIA codes stamped on the speakers to be sure.
Agreed, my feeling is also that it's a tone box, but i surely don't recognize much beyond that. The openings in the baskets have me thinking maybe Quam.
My sentiments exactly (albeit a small one; maybe a home organ).
They look to contain decent looking 8" extended range drivers with AlNiCo magnets; might come in handy for something. If they're cheap and close by... they might be worth the effort of picking up.
