So.. I’m refoaming a set of rs4bs, and I have encountered a 1/16” paper riser that lives under the original foam. I have reconed speakers before, but never encountered this. In the past, I had been advised to scrape down to the raw metal of the frame so you have a clean, solid surface to glue to. I just decided to remove the paper riser on this first driver and continue as normal. Now I have glued the new surround to the cone and Lo and behold, the outer edge is 1/16” above the metal frame. Has anybody else experienced this? Should I leave it and glue to it, or....? I can’t find any mention of it anywhere, but maybe I’m using the wrong search words. Attached are some images of the paper riser still attached.
