I recently purchased a pair of Polk RTA 15 Tl speakers and they have the sl2000 tweeters. I am sure the sl200's were installed by the previous owner, as I know that isnt what they originally came with.I just blew one of the tweeters. Can the peerless tweeeter be used as a replacement? I have a peerless sitting here,but notice that the faceplate screw hole pattern isn't right.I tried switching faceplates but the peerless wont work with the sl2000 faceplate.Is it safe to use the peerless in the rta15tl?
