Driver foam surrounds gets old and brittle with use and years, so vintage drivers (normally bass drivers) will need new surrounds, if your speaker has distorted sound in the lower tones, take of the speaker grill (USA "frets") and if it looks like this, its time to start working.
The old surround and old glue, will have to come of, the best way to do it is with a hobby knife or razor blade. On the basket you can scrape and cut it of easily, but on the cone (mostly paper cones) you will have to work with care, not to damage the cone, DO NOT USE ANY SOLVENTS HERE.
With everything clean and looking like new, apply glue to the cone where the inner edge shall go, You may wish to make a pen line all around the cone, marking the inner edge diameter.
