I have a pair of Polk 7B's with the Peerless tweeter and like them but have a chance to get a pair of SDA CRS in very good condition. This version has the two Peerless tweeters in each speaker. If the CRS can be placed within 10 inches of the back wall(on good metal stands), they would save me space in my small apartment. I did not buy them yet but I would like a little feedback on both. I do not have room for both so it's one or the other. I am a trained pianist and appreciate midrange accuracy. I listen exclusively to Jazz and Classical music.
