Making speakers sound like new again for over 20 years.

Refoam Kits

       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.

Here's What You Get
:

Most Kits include all the materials needed to repair two (2) speakers:

  • Refoaming Instructions
  • 2 New Surrounds
  • Shims for Centering Voice Coils
  • 2 Dust Caps (If Needed)
  • 1 Bottle of Specially Formulated Surround Adhesive

    Midwest Speaker Repair ships refoam kits USPS Priority Mail or UPS Ground.
    International shipments will be shipped through USPS Priority International Mail.
    Speaker Size
    Use the tables below to determine the correct surrounds for your speakers. 
    The measurements listed here do not have to match your speakers exactly for the surrounds to work.  Some surrounds will fit better if they are gently stretched out or if they are a little too big.  The most important thing to remember is that the surrounds must overlap the speaker cone on the inside edge and the speaker basket on the outside edge. If the measurements listed below do not match your speakers, please call.  We may have other surrounds that will fit your speakers.
