[QUOTE="ciaonzo, post: 8654654, member: 607015"] This is called cavitation. It is the result of too much power at frequencies above tuning, for the amount of airspace the driver is in. You will need to either scale back the power at those frequencies by adjusting down the low pass crossover point or by lowering the overall gain. Otherwise, you will need to shrink the volume of the enclosure to offer better damping (cone control) if you wish to continue with the current power levels. This will change tuning but you may not mind. [/QUOTE]
