Hey Kent! I have made considerable progress with my Gradient SW-63s. I got the offending one apart and not only are there radial cracks in the surrounds (what I could see through the mesh with a flashlight) but also significant detachment of the surround from the cone. When I push gently in on the cone I am getting a stiff, gritty feeling and a scraping sound, maybe voice coil rubbing? Anyway, I feel I am way beyond a refoam job. I was in communication with Jorma Salmi at Gradient and he put me on to a replacement driver with a rubber surround that they had tested and found worked well. I think it'll cost me only a little more for four new drivers than to pay shipping both ways and $200.00 for a refoaming. Seems the way to go. Right now, I am trying to scrape off the goo that was squeezed around the underside of the speaker's rim and used to dampen and keep the metal mesh from rattling. It's going to take awhile. I am wondering, in your experience, what might be a good replacement for this goo? It seems like a silicone compound. It's sticky and elastic but has not hardened completely. It's still a bit flexible. Have you run across anything like this? Thanks, George
