How to Re-Cone Your Speakers

If you have a broken or damaged speaker you may choose to re-cone your speakers rather than replace them. This is not a simple task, so you have some research to do before you begin:

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

• computer with internet access
• basic tool set
• utility knife
• re-coning kit and instructions
• solder and soldering iron

1. Check the Internet to see if there are re-coning parts available for your particular speakers.

2. Decide if it is economically feasible to re-cone. If you are using expensive or antique speakers, it may be worth it to re-cone them.

3. After obtaining a replacement cone assembly, remove the damaged parts of the old speaker cone. Use a sharp utility knife to carefully cut away the old cone material.

4. Clean the permanent parts of the speaker assembly such as the magnet, voice coil surround and basket. Use a lint-free cloth and at least 90% isopropyl alcohol or acetone to remove dirt and debris.

5. Your re-coning kit will come with instructions; follow them carefully. You should use the included adhesive to attach the surround, cone and voice coil to the basket and magnet.

6. Reattach the wires using small amounts of solder and a soldering iron. Allow the adhesive to dry completely and cure before using the speaker.

Tips & Warnings

• Consider the cost and convenience as well as your technical abilities before attempting to re-cone your speakers.
• Getting adhesive or solder on the functioning parts of the speaker will damage them.
• Use caution when working with sharp tools and a soldering iron.
• Do not drop the magnet and basket assembly as this may damage the speaker beyond repair.
