I have a speaker where the rubber / foam surround has come apart from the cone (plastic), I want to try and re glue them together but I'm not sure what glue to use, I'm leaning towards contact adhesive at this stage because if applied correctly it forms a very good bond but also does not become hard when it sets, I've Googled but there is conflicting advise out there, here's to hoping a fellow forumite can offer some advise.
