B&W 801 Matrix 2 Woofer replacement

One of the woofers in my 801 Matrix 2 is misaligned and dragging at the bottom of the cone. I'm hoping the repair shop can realign it properly. Failing that, I'm going to look into reconing both woofers. Has anyone ever reconed the woofer? What's the source?
Thanks!
Cheers!
