One of the most common problems with audio systems is that the speaker cones get torn. Knowing how to fix your speaker cone will help you get your speaker working again. This is not a very complicated job, and with this guide and the right tools you can replace the cone on your speaker. Save yourself the trouble of calling a technician and paying him by fixing the speaker yourself. Here’s how you do it.

Step 1 – Getting Started

Unplug the audio system from the plug socket and disconnect the speaker wires that are connected to the amplifier.

Step 2 – Remove the Speaker

Remove the speaker from the box; you might have to remove some screws from the speaker box to remove the speaker.

Step 3 – Cut out the Cone

Using the knife, cut right around the edge of the speaker to remove the cone. Now peal the cone back and remove it from the speaker by pulling it apart.

Step 4 – Remove the Gasket

Use the knife to remove the gasket. Slide the edge of the knife between the inner portion of the speaker and the gasket and pop it out. Remove the gasket and discard it.

Step 5 – Cleaning the Speaker Frame

With the knife, scrape the dried glue from the frame of the speaker. You might need to use glue solvent to remove all the dried glue from the speaker frame.

Step 6 – Buy a New Speaker Cone

Make note of the size of the speaker frame and go to the store to get a new speaker cone. You can also buy one online and have it delivered to your home.

Step 7 – Making Sure the Cone Fits

Take the index card and cut a 2 inch piece and slip it in the gap of the voice coil and fasten it with the masking tape. This will help you make sure your new cone fits correctly in the speaker frame.

Step 8 – Apply Glue

Make sure the speaker frame is clean from all the old glue before applying fresh glue. Apply a coat to the speaker frame.

Step 9 – Place the New Cone

Remove the new cone from its package and place it on the speaker frame. Make sure it sticks to the glue you applied. It will take about two days for the glue to dry.

Step 10 – Fix the Gasket

After the glue has dried, remove the masking tape and the index card from the voice coil. Now fix the gasket to the speaker frame. Apply glue in the region of the voice coil and place the dust cap over the voice coil.

Step 11 – Solder the Wires

Use the soldering iron to solder the wires to the terminals.

Step 12 – Reassemble the Speaker

Reassemble the speaker into the box or its housing and test it to check if it is working properly. That’s all there is to do to replace the speaker cone on your speaker.
