Many older high-fidelity speakers have foam outer surrounds that are susceptible to rotting out over time, leaving ninety percent of the speaker in perfect working condition but unusable because of the damaged surround. There are several factors that affect the life span of a foam surround such as climate, usage, and speaker location relative to sunlight (direct sun rapidly deteriorates foam surrounds).
If you bring your speaker into Santon Audio, we can replace the foam surround, restoring your speaker to almost-new condition for another ~15 years. We also offer D.I.Y. Refoam Kits that you can purchase to complete the repair at home. Refoaming a speaker isn't terribly difficult, but it is time-consuming and you only get one shot at it. Unless you have experience working with adhesives, we recommend bringing your speakers in for repair.
