Whether you have a home stereo system, work PA system or guitar amplifier, replacing your speaker cone is the best course of action if your speaker has begun to sound dull or produce poor audio. Many speaker cones produced prior to the 1990s had diaphragms made of paper. Paper cones worked well. However, after many years of constant use or moist atmosphere, speaker cones would tear. Audio that is too loud can also rip cones. Installing a new speaker cone is the best way to fix this problem.

Open your speaker cabinet. These are often made of either wood or press board. Most speaker units are held together using screws, staples or glue. Use your screwdriver to open the case if you have screws. It is not recommended that you attempt to open a speaker unit that is stapled or glued, as opening the unit would damage the aesthetics of your speaker.
Many speakers that are sealed in the back have their speaker cone mounted from the front. You may be able to unscrew your speaker cone from its four anchor screws in its four mount corners.
Disconnect your speaker cables. There will be two wires coming from your speaker. These will be connected to either contacts or more wire, and can often be disconnected without having to cut the wire. Pull them apart.
Remove the speaker. There will be four anchor screws holding your speaker in at the cone's four corners. Turn these screws counterclockwise to remove the speaker. Once it is removed, set the old speaker cone aside.
Replace the speaker with a new one. Screw your new cone in by turning the screws clockwise.
Connect the speaker wires to the wires on your speaker cabinet. These should connect by special plastic connectors. If not, use a wire stripper to remove some of the rubber coating from your speaker wires as well as the speaker cabinet wires. After stripping these four wires, you can twist the wires together in pairs, matching each speaker wire with one case wire.
Close the back cover on your speaker case. Then connect your speakers to an audio device and play sound. You will hear audio coming out of your new speaker cone.
Tips and warnings
- Searching the Internet is the best way to find the proper cone size for your audio unit.
- Speaker cones are made of different materials. Buying a cone similar to the one on your other speaker will help audio sound equal from both the left and right sides.
