I had the same problem with my Forte's and found the voice coils in the horns blown. At the time when Klipsch owners were like Harley Owners, I was given a set of voice coils for free. Recently my wife fried the coils again and when I went to the local audio shop they were ready to charge me $30 each coil. If anyone knows a better source for where we Klipsch-aholics can get these coils cheaper I would appreciate a message.
