Foam edge deterioration is the most common problem with woofers and some midranges. The foam edge (or surround) usually wears out after ten or twenty years. Midwest Speaker Repair can replace the surround and make your speakers sound just like new! This process is called refoaming. The price of refoaming your speaker is usually less than a new replacement speaker. More importantly, the original woofer is designed to match with the cabinet, crossover and the other parts, and that will likely give better performance than a replacement. If we determine a replacement is the better choice, we will let you know. We do have a wide selection of replacement speakers to choose from. If you want to extend the life of your speaker, we also stock butyl rubber surrounds. Please check the available sizes and the dimensions to see if they will fit on your speaker.
