My directions for replacement of old foam surround with butyl rubber surround.
 
(Do not use weldwood on foam! Foam will disintegrate)
 
I use Weldwood contact cement.
 
(Shoegoo is too thick for this application don't do it.)
 
Peel top ring carefully as you will reuse.
 
Keep all solvent and glue to only contact areas, do not leave any foam bits on cone.
 
Peel old foam with '''care not to damage cone or tear spider below'''. most time old foam will just pull or rub off easy, I brush acetone carefully to melt the rest off.
 
Pre brush clean at '''glue areas only''' with acetone, cone edge, basket ring then dry '''be sure to have removed old foam or rubber.'''
 
'''IMPORTANT: Start with basket ring, then cone edge'''. Your new butyl will ripple if you use too much or do it first.
 
Both parts glued now get promptly attached again with care to keep cone centered.
 
Glue top ring on and don't worry about perfect adhesion to cone yet just set it face down for 10 min.
 
check for proper adhesion to cone again after 10 min the hi spots should press and stick now.
You
You
can recheck high spots a few more times till mid cure or 30 min.

Lastly you can flip the speaker over and use the same glue or even super glue to do a gap fill under your speaker cone edge assuring no air gaps. '''Do not put glue on the flexible suspension part'''.
 
I leave any repair like this alone before testing 24 hours but you can re mount after a hour.
 
I use black permatex gasket cement on cone tears.
