Are all impedances the same? If so, this happens when one sub is mechanically blown. This means that the suspension lets go. At this point the cone of that sub is no longer controlled and reflexes with the pressure building up in the box.

that or the coil of one is a bit burnt and the impedances are a little off. more likely its blown or they impedance is not matching

i bet the are in a ported box and the sub that is moving the most is closest to the port. loading issues. can be fixed sometimes with a loading wall..

yea i think it might be blown then, looks like ima need a new sub, and its not ported,

its in a sealed box, its sub has its own chamber the other 3 hit fine

but the 1 hits slightly harder and its noticeable

Sub could possibly be out of phase?

This is the most likely cause.

dude said the enclosure was sealed up, though.

check the coils with a dmm and see what they read. Also I didn't see it mentioned. Are all 4 subs the same age, and have the same play time? //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
