I would take a close look at all the drivers first before opening up the speakers to make sure you don't have woofer and tweeter damage. other than that the problem has to be in the protection circuit or the crossover itself which would take further examination to determine the problem.
Seeing as I have little experience with these things it might be a lost cause. The grills to me appear to either be stapled or glued on. I didn't even attempt to take the AR speaker grills off before selling them. They were just glued in 6 points if I remember. The grill cloth on these speakers covers 3 sides. They show no signs of having ever been off since they were put on. I imagine a repair shop would charge a lot just to get inside. Then that begs the question is it worth it when my only intention was to resell them? They might be worth $75-$100. They weigh 40 lbs a pop too. Those speaker manufacturers are pretty crafty. Oh sure you don't want vibration so you glue everything up nice and snug but you also don't want anyone to be able to fix them so easily. If they were in more demand I'd sell as is but now I don't know if that's wise.
