DIY: Coaxial Speaker Project
This is a coaxial-connecting cable. (BNC connectors and cable image by Albert Lozano from

Coaxial connections are used on older audio setups as well as on citizens band (CB) and short wave radios. Coaxial speakers can be made from ordinary speaker connections. There are three reasons why a person would want to make their own coaxial speakers.

1) Better audio can be received from better quality speakers.

2) Coaxial connections can be attached to larger speaker systems.

2) Making your own coaxial speaker often is cheaper than purchasing a speaker that is designed specifically to connect to coaxial connections.

  1. 1

    Cut off one end of your coaxial cable using your scissors.

  2. 2

    Strip away 2 inches of the cable's rubber coating. This will expose two wires.

  3. 3

    Melt some solder on the tip of your soldering iron.

  4. 4

    Touch one of the stripped wires to a contact on the speaker. Which one does not matter. Transfer the bead of your solder to this junction.

  5. 5

    Touch the other wire to the other contact on the speaker. Solder the junction.

  6. 6

    Connect your speaker to your device. It should now play audio.

Tips and warnings

  • If you don't want an exposed speaker, used stereo speakers can be purchased at thrift stores that can be soldered in the same way.
