B&W 802 Series 2 Replacement Woofers?

I'm in need of a replacement woofer as I am getting a rattling sound from the lower driver in one of my speakers. After much searching, I am unable to find any information. If anyone out there has advice, that would be great! Thank you.

Good Luck
Is it the lower woofer on the right speaker?
No, lower on left. At certain frequencies and volume, it's slightly fuzzy, like it cannot move 100%
