Jeff,
First, very sorry to hear your story. Second I would like to understand the cause of it. It sounds like the driver has been bottomed out very often. Is the sub a vented box? The reason I ask is because vented box has 3 times excursion requirement below resonance frequency. Without a rumble filter, the result will be much worse. Our amps have adjustable rumble filters because each person has different playback habit. For maximum play back level, the rumble filter should be set to highest 28hz setting. Amp clipping is different from bottoming. The amp has short circuit protection for excessive current. However, in vented box, the excursion below resonance frequency does not require a lot of current. So the only way to protect it is with excursion limiter. But the excursion limiter needs to designed specific for a driver. It is not just my amps, any other high power PA amp can do the same thing. Over excursion is particularly problematic with aluminum former. I would like to keep my customers happy. Apparently you are not now.
Regards,
Brian
