Tears and holes in speakers are an inevitable part of life, especially with children, pets and the occasional speaker-relocation mishap. Fortunately, small tears and holes--particularly in the outside section, called the speaker surround--are an easy fix. The main concerns when patching are maintaining the structural integrity of the surface and allowing freedom of movement after repairs are completed. Since speakers constantly vibrate to produce sound, the patch material must move in tandem with the speaker surface while still filling the hole and maintaining the bond. Silicone sealer, available at any hardware store, meets those needs perfectly.

    Fixing Holes In Speaker Surrounds

  1. 1

    Remove the speaker grill frame to expose the speaker. Most frames are attached with Velcro or plastic pins and are easily removed.

  2. 2

    Place the speaker cabinet on its back, with the speakers facing upward.

  3. 3

    Remove the damaged speaker's mounting screws with a screwdriver. Put the screws aside for safekeeping.

  4. 4

    Pull the speaker out of the cabinet, lying it face-up on the cabinet top. The two wires may be removed to facilitate easier work conditions if necessary, but be sure to note the colour and location of wires for reassembly.

  5. 5

    Place a small strip of wax paper on the underside of the hole or tear and hold it in place with a finger.

  6. 6

    Apply a small amount of silicone sealer to the top of the hole or tear. Apply just enough sealer to fill the damaged area. A pea-sized amount or less should be sufficient.

  7. 7

    Place another square of wax paper over the silicone, forming a sandwich between the upper and lower repair area. Gently pinch the wax squares together, forcing the silicone to cover and penetrate the damage, and smooth the surface.

  8. 8

    Leave the wax paper in place and allow the silicone to set for the recommended time on the package--usually 24 hours.

  9. 9

    Peel the wax paper off carefully and inspect the repair. If the hole did not seal completely, or gaps are present, apply more sealer and repeat the wax paper-and-setting process.

  10. 10

    Reattach the speaker wires and reinstall the speaker into the cabinet.

Tips and warnings

  • Use silicone sealer in a well ventilated area and follow all warnings on package.
