Thoughts on extending speaker life.

For those of us who own speakers that are past a few years old, and those same speakers utilize dynamic drivers, what are your thoughts on extending the life of the rubber surround ( assuming that your driver utilizes this kind of design).
In general, as the driver ages, the likelihood of the rubber surround failing increases. Without actually replacing the driver ( not possible in some instances) what do you suggest to extend the life of the driver(s), if anything?

For those with other types of driver design, what are your concerns about the extended usage of this kind of driver as it ages?

AR 18S surrounds crumbled after maybe 10 years. Mission 761i will be 25 (years) in a month or so. surrounds look like new. Third pair, 14 years, looks like new, too. Fourth is still too young to tell. None of them has ever been treated or paid any attention to.

Could it be that something about materials used has improved over the last 20-30 years?

I would not apply anything on surrounds. There is more chance I would damage them, poke the hole or something else disastrous, than that I would extend their lifespan by a few more weeks. I do not think it is worth it.
