Default Polk Sub ???????

Doing a HT on the cheap for a neice and I came across this Polk sub on Ebay.


They sold it as a 10" sub, but that's a passive radiator on the bottom. I popped it off and found 2 - 6.5 drivers set up like a 6th order isobaric.

Referencing the only numbers I could find on the bottom, I couldn't find anything at all about them on the polk site (no surprise).

Also you can see in one of the photos that there's a blue terminal post between the two red ones. What's that for??

I bought it & have it here, and am presently scratching my head, any info would be most appreciated.

Thanks, Ralph
Probably a silly question, but ........

Looks like a PSW120 or PSW50, probably a very old item, probably came in the market before these two discontinued subwoofers.
