Following up on one of my earlier posts, the CS7.2 woofers that seemed hopelessly damaged have been repaired by Coherent Source Services (Rob Gillum). He had to completely rebuild them (shipping damage prior to me purchasing them), but they are now back, installed, and playing music. I don't know how much burn in time they might need, but the speakers already sound fantastic (first I've heard them since purchasing them). Rob was extremely helpful throughout this process, and I unconditionally recommend his services.
