Hey people,

What glue is the best to glue between surround and the diaphragm of the cone like in attached picture above (the small piece)? And what do you think, if it will be better if I'll change this rubber surrounds to the new one? and what glue should I use in this case?
I saw some video in YouTube the guy glue the surround with diaphragm with nail polish. what do you think?
Thank you.
