Epoxy.
Preferrably the Industrial type which takes *hours* to cure, rather vthan home use "5 minutes" type.
And the clear type, not the aluminum dust filled one.

I use CIBA made Araldit, the one which is viscous as honey at room temperature.
Are you building a speaker from scratch or trying to reglue a displaced/uncentered one?

Because if already magnetized, "pull" will make you crazy, speakers are built with unmagnetized ferrite (alnico/Neo, etc.) and then magnetized after assembly.
