I dont know the specific year but the crossover is Type E2 so somewhere between 1982 and 1985. The midrange model is K52H.

Thanks guys I really appreciate the help and welcome. I have done as suggested and the woofer has no rubbing and feels identical to the other speaker, all screws on the crossover have been loosen and tighten again.I tried covering the drivers and the distortion seems to come from the mid range driver.

Hello, this is my first post, so I appreciate the input in advance. Recently I obtained a pair of Klipsch Heresy locally and I have been enjoying them very much but this morning while listening to a piano recording I noticed some kind of distortion on one of the speakers, I thought at first it was the recording and tried others and experienced the same problem, then I tried switching the speakers and the problem followed the speaker, also tried a pair of KG 3.2 with no distortion. I never noticed this with other types of music and even now I can not clearly hear most of the time but as I mentioned its allways there when listening to piano recordings the louder it gets the more I can hear it. I would really apreaciate any advice on where to start. Thanks.
