Thinking it would be a pice of cake to purchase a new surround kit for my JBL 4412 woofers , I have discovered that (for the first time in my life) I was mistaken! One site shows a 128H with a flat (non angled) point of attrachment to the cone, with a slightly smaller surround ID. Fact is that my 128H-1's are attached at the back side of the cone, and at an angle. Has anyone purchased a surround kit that they are happy with? I sure would appreciate knowing where to purchase the proper one!
