How To Use Coax or Coaxial As Speaker Wire

Coax, or coaxial cable, is famous to most satellite technicians as the wire that you use to connect the cable to your TV set, and speaker. It is most commonly used for video and signal purposes, and it is convenient to use. At the same time, its thickness and lack of flexibility present wire management problems and can easily be used to connect speakers to an audio receiver or soundbar in a pinch.

What is Coaxial Cable?

According to WikipediaCoaxial cable, or coax, consists of an inner wire surrounded by a concentric conducting guard, with the two separated by a dielectric (insulating material). While coaxial cables also have a protective jack or outer sheath. The term coaxial means that the inner conductor and the outer shield share a geometric axis. Coaxial cable is one of the essential accessories for satellite dish installation, and connect speaker. If the core wire in coax is damage internally without any sign of strip in the protection insulation part, then it is good to replace it with the good ones.

Coaxial cable can be use as a transmission line for radio frequency signals. Its applications include:

  • Computer network (e.g., Ethernet) connections
  • Feedlines connecting radio transmitters and receiver devices to their antennas.
  • Digital audio (S/PDIF).
  • Distribution of cable television signals. 
  • Coaxial wire can be use to connect speakers from audio amplifiers.


How to Use Coaxial As A Cable To Connect Speaker

Step 1

Cut off any existing or new connectors with a sharp utility tool or use a knife.

Step 2

Measure the length of the wire you will need and cut the cable to the correct size.

Step 3

Clean out 1 1/2 inches of the outer nonconductor from each edge of the cable.

Step 4

Carefully separate the wire shielding from around the core wire (thick filament) on each end.

Step 5

Wrap the braiding into a single tight bunch of wire.

Step 6

Remove the glassy insulation surrounding the core wire on both ends with a wire stripper tool.

Step 7

Plug the stripped Coaxial core wire to the red connector on the speaker and back of the satellite receiver and the braided bunch to the black connector on the speaker and back of the satellite receiver.
