Emailed Australian Klipsch Reps with photos of the woofer suspension falling apart. Said it was a manufacturing fault and I want something done. They were out of warranty but argued that woofer failures on a $20K set of speakers after seven years was not acceptable. Klipsch USA asked for my serial numbers and dispatched six replacement drivers, all matched pairs.
On another note I did try and re-cone the woofers but they are not serviceable.
