B&W 802 Series 3 Woofer Replacement

One of my active nephews took the grill off of an 802 Series 3 and went to town on the woofers. I looked around on the web and it looks like replacements or upgrades are hard to find, esp. from B&W. Does anyone have any ideas on upgrades and/or replacements? thanks.
Replacement woofers are available from B&W.


Enter model, MATRIX 802 S3

Woofer listed as Base Unit, part# ZZ08073
You might check with Speakerex, they can most likely hook you up with a replacement driver.
