13. Will new foam surrounds degrade?

13. Will the new foam surrounds also wear out?
The foam surrounds we offer here are of a high quality with more reliable fillings and materials, making them very durable. The original surround rims were composed differently and were less durable as a result. The lifespan depends, amongst others, on the humidity, smoke, sunlight (UV radiation), heat etc. The worst place for foam surround rims is the parcel shelf of a car.
Audiofriends examined the products of its many suppliers. The foam surround rims of Audiofriends will last till 20 to 35 years, depending on the circumstances. Old rubber surrounds may harden or lose their original shape. The surrounds we supply should at least last 40 years, depending on the circumstances.
