Hello i have a pair of Athena AS F2 which the tweeters have gone out.I have looked and looked for replacements to no avail.i finally sent Klipsch an e mail to ask them if they new where i could find replacements,To my surprise the responded to me telling me they have replacement tweeters for the Athena speakers, Part number-5DR53127 for $28.78ea. +s/h. I just thought i would share this info,because iv have seen many threads of people looking for these tweeters in my search for replacements.The number to call and order them is 1-800-554-7724
You should also post this in the Athena Owners thread as it is very useful info. Thanks!
