I think I have a bad tweeter on one of my Polk Monitor 10A speakers and need to replace it. I have a pair of Polk Monitor 7A speakers which I do not use and those also have the peerless tweeter. Is the tweeter on the Monitor 7A the same as on the Monitor 10A so I can replace it with that one? is the Monitor 7A peerless tweeter the same size and exact tweeter as used on the Monitor 10As?
