Look to see if somthin got in there and if not if the subwoofer is ok you might have to much of a high signal going in to the sub. Sub are only reted for low Hz and not High Hz and if you get a high in to the sub the cole cant moves fast to me the high Hz that is getting.
The best way to fix that is with a crossover and make shour that you crossove is for lowbuypass only.

There are several online box building programs available. Since I am an authorized RE Audio dealer, I recommend the program on the www.reaudio.com site. However, if you are looking for something exotic, you probably won't be able to find it for free. Happy Hunting.
MA Audio's website has the recommended box volume and port size online here. A ported enclosure needs 3.0 CuFt of internal volume and the port should be 48 sq/in and 14.5" in length. A 4X12" rectangular port would give you the recommended 48 sq/in. Using 3/4" MDF, a box 16X18X25 has an internal volume of 3.25 CuFt allowing .25 CuFt for the sub and port displacement.
ive had that happen to me with 2 12in infinity subs . (my first system) haha i dont knwo what it is but it sounds like a piece of solder weld has broken off in there where the voice coils conect to the cone.. its a manufacture defect nothin you can really do about it without taking it totally apart ... then the hard part is putn it back together .. specially if it wasnt suposed to ba taken apart lol
Optimum Vented Box: 4.5 Cu/Ft Round Port Diameter: (3) 4" Square Port Area: 37 Sq/In Port Length: 17" Optimum Sealed Box: 1.75 - 2.5 Cu/Ft these are your options as you can see if your short on space your sub will love a 1.75 to 2.5 sealed box but if you have THE right ported box you will get better bass with less power but at the end of the day that sub will Pump wish i had one good luck hope this helps you info from manufacture cheers bronson
