The most common problem with speakers are rotted, torn or damaged surrounds. The surround is the outer suspension part of the cone. Constant vibration, time and the environment cause foam and rubber surrounds to degrade. Cloth and paper surrounds can become brittle. This causes distortion and poor performance.
