I'll take some pics of the tear when I get home and post them. Admittedly I was so bummed that I could barely even look at it, plus all the other drama of a move made it so that I don't know how bad it actually is. I've never repaired a cone before, however. I've reviewed some of the other posts on this community from people who had the exact same thing happen. The consensus seems to be that since this is a passive radiator it's easier to fix since it's just a matter of creating a closed air system. Cigarette papers or coffee filters and white glue.
I called Klipsch and they said that it's possible that the Forte III passive radiator MAY fit, but that modification to the cabinet may be required. They said to call back in September once the speakers are out and they've had a chance to test it themselves.
