I sent my A2 woofers directly back to Snell. They outsource the reconing, but they make sure it is done to spec and meets their quality standards. It was a little extra peace of mind for me. As it turns out, Snell sent one woofer back to the shop to be redone before they returned them to me because it didn't meet Snell's standards. I received the woofers back, I reinstalled them, and the results were great. It wasn't cheap, but I felt it was worth doing it the "right" way, and I was pleased in the end.
