Marantz Mid Range Receiver Audiophiles, Can You Help Me With My Marantz Speakers?

Audiophiles, can you help me with my Marantz speakers? - marantz mid range receiver

I bought a pair of Marantz speakers at a local store Army Hello. I literally ran into them. I bought it for $ 15 for the pair.
Model SP-1050, 10 "high compliance woofer, 4" liquid cooled midrange, 3 ", liquid-cooled tweeter.
32 "high-floor models; first condition Inside & Out; function perfectly.
I do not sell them, but I'm curious to see how much they are worth.
