Pölk Monitor 7A Driver

Options
I am the proud owner of two pairs of 7a's. First pair for $20 in garage sale. Loved the sound but did not know the Peerless tweeters were missing. Bought a second pair with Peerless tweeters. Wow what a difference. One the speakers is not working and wanted info on the driver I have no Polk stamp could they be the MW6500 or aftermarket? I bought a pair of monitor 4 to recuperate the Peerless and put them in my monitor 7. The drivers in the monitor 4 are Polks MW6502, can they replace a MW 6500? I hear that the MW6500 is 8 ohs and the MW6502 is 4ohs. The answer will help to decide if I keep speaker for parts.

    Yes, definitely MW6500 in 7, 7A, and 7B.

    That is interesting that your M4s you found had a MW6502 paired with the Peerless. If they came from Polk that way, it is the first time I've heard of it. The Peerless M4 were 8 ohms impedance afaik and, as you say, the MW6502 is 4 ohms. Can you verify that the Peerless in that one were not the 4 ohm version, which I have not heard of Polk using, but who knows?
