Aging rather than misuse is the primary reason why a speaker foam surround rapidly deteriorates. This deterioration, or speaker foam rot as some people call it, occurs anytime between 10 to 15 years after you purchased and began to use the speakers. The most common indication that your speaker foam has deteriorated is when the speaker produces distorted sounds.
What you need to have before replacing the speaker foam surround:
- The speakers needing the foam surround replacement.
- Obtain a speaker repair kit. Typically, a repair kit would include new foam surrounds and a special adhesive that you will use during the replacement of the foam.
- Have the necessary tools needed before proceeding with the replacement. Make sure to have a screwdriver and a utility knife by your side, as you don’t want to stop your momentum in replacing the foams when you suddenly remember you don’t have either one of them handy.
Once you have made sure you have the needed items, replace your speaker’s foam surround by following these instructions:
- Take the speaker out from its cabinet. Use the screwdriver to remove the screws.
- Remove the wires connected to the speaker. Before you do disconnect the wiring, take note of how the wiring looked for later use.
- Detach the gasket from the speaker using your utility knif. This is to remove the remaining parts of the deteriorated foam. Be sure not to injure the speaker itself while removing it. Afterwards, get rid of the leftover foam around the speaker’s cone.
- Daub the edges of the speaker’s cone evenly with the special adhesive. Secure the foam surround by gently placing pressure around the cone’s edges and the inner part of the foam surround, after which allow the adhesive to dry.
- Daub the outer frame of the speaker. Again, use the special adhesive that came with the speaker repair kit. Fit the foam surround, and lightly press the outer frame of the speakers using your index finger.
- Press the cone to make sure the cone’s speaker is centered and secured. Once sure that the cone is secured, let the adhesive dry for an hour.
- Daub the edge of the speaker and secure the gasket that was detached earlier. Leave the speaker face-down to let the adhesive dry for another hour.
- Reconnect the wires. Take into account how the wiring looked before you disconnected the speaker. After reconnecting the wires, take the speaker back to its cabinet.
Some people may resolve to purchase new speakers, but why should you buy a new set when you can replace the foam surround by yourself?
