My Epos ES11's have a rubber seal around the woofer that has come unstuck. On some tunes I now get a slappy noise where the loose rubber is vibrating. I need to glue it back onto the main cone but was wondering what to use. Its going to be difficult to put much pressure on as I don't want to take the speaker apart so something that will stick well and quickly would be nice. Any suggestions or will plain superglue be ok?
