Speaker cones are made from paper products, and it is not unusual for them to suffer small nicks and dents. A dent does not actually affect the sound of the speaker, but it can lead to more serious problems such as small tears in the speaker cone if it is not repaired. Small tears affect the sound quality of the speaker by producing a distorted or muffled sound. The different techniques for fixing a dented speaker cone all aim at pulling the dent out and allowing the speaker cone to regain its shape.

- Moderately Easy
Things you need
- Masking tape
- Cardboard tube
- Vacuum cleaner
- Krazy Glue
Tape the dent with a piece of masking tape. Duct tape works as well but it leaves more of a sticky residue. Place the tape on the dent. Gently pull the tape until the dent pops out.
Put a cardboard tube over the dent. An old paper towel or toilet paper tube works fine. Place your mouth over the tube opening. Suck the dent until it pops into place. An alternative method is to use a vacuum cleaner. Place the vacuum cleaner hose over the dent. Turn the vacuum cleaner on.
Pull the dent out with Krazy Glue. Place a small drop of glue on your finger. Place your finger on the dent for 20 seconds to allow it to bond. Gently pull the dent up with your finger, twisting your finger as you do so to break the bond.
Bend a small pin at a right angle. Stick the pin into the centre of the dent. Carefully pull the pin upward until the dent pops out.
