PSW150 hum issue

Hi all....
I have a PSW 150 sub with what appears to be a blown driver. The actual symptoms include a low hum during all sound activity. Here are some other details:
-Hum occurs in both polar phases
-Hum occurs through all frequency ranges for sub
-Tried switching inputs
I discovered this problem when it was hooked up to a new receiver. A smaller Yamaha sub is now in its place and works fine (just not powerful enough).
Any ideas?? Thanks!
