Hello. I bought a pair of r28f speakers a couple of months ago and unfortunately the tweeter of one of them sounded a little lower than the other( some high frequencies didnt sound at all). So i watched some videos on how to remove a klipsch tweeter to check if it was blown. In addition i've removed the tweeter and accidentaly cut off the diaphragm connection. At last I can't find a replacement tweeter .Do you happen to know the R28F tweeter code number cause the code number the reported tweeter has doesnt show any results on any shop ! Thanks.
