Since you didn't include any pictures, I'm gonna go out on a limb and say Monitor 10

A photo with the grills off might help us to help you narrow it down to one of two models, based upon the time frame you mentioned. It appears as if @pitdogg2 nailed it though, honestly (1977–1982). The tweeter style is what we are specifically looking for. A close up of the tweeter, along with another shot of the other 4 drivers may help us to confirm for you.
Oh, my manners. Please allow me to offer you a very warm welcome to Club Polk.

Monitor 10 with Peerless tweeter. Worth whatever someone is willing to pay, which ain't going to be much.Political Correctness'.........defined

One is earlier than the other; the one that had the stapled on stub that someone tore off. What does that one look like with the grill off?
The one you showed dates around 1979. I'm not sure when the midwoofers and the passives stopped being the silver basket style and went to a black painted style but it was some time after 1979.
If you remove the crossovers there could be a date on them, as well as the midwoofers and the tweeters.George / NJ

Here is the other speaker which is the same as the previous one.
From what I gather these aren’t worth much. They still sound great! I may try to get $100 each.

So, is the older one Rosewood vinyl and the other one Walnut vinyl? If so, that will reduce value.George / NJ
