Why Is One Speaker Louder Than Another?

There are a number of reasons why one speaker is louder than the other. The most common reasons are:

  • Volume settings
  • Balance Setters on Amp
  • Disconnected Stereo Cable
  • 3.5mm Headphone Jack
  • Loose HDMI or Optical cable
  • Faulty amp
  • Faulty source

The first place to check is the back of the speaker. Ensure the cables are screwed in properly: this is easily the number one reason for this happening. The second most common reason for one speaker being louder or quieter than the other is the 3.5mm headphone cable malfunctioning. If you are using a portable source and the 3.5mm cable, it can degrade with wear to the point that there is a short in the wire. In this case, you may be able to temporarily bend the wire to find a spot that works – but you will need to eventually replace this cable.

The problem of one speaker being at half volume is almost always the speaker cable or the 3.5m headphone jack. Make sure its pushed in all the way, or try bending it in small increments until you find a sweet spot. It’s a good idea to replace that cable with a new one.
