How to Fix Rear Speakers Not Working Home Theater

Home theater setup can be a tricky affair if you just acquired a new unit for your house. There are numerous wires and settings to deal with; things can easily go haywire! 

One of the most common issues you’ll come across is that there is no audio coming from the rear speakers. In this post, we troubleshoot possible ways of fixing “silent” rear speakers when you turn on your home theater system.

Overall, quiet rear speakers could be a result of various issues, and these will involve different solutions. As such, any of the steps stated below represents a possible answer to the problem; be sure to test the speakers after each step.

1.The first thing you want to do is check that the rear speakers in your home theater system are properly connected to the A/V receiver. Depending on the model you’re using, you can do this by verifying that the A/B speaker selector is at the correct position.

In other words, if you connected the speakers to the A speaker connection on the rear of the Audio/Video receiver, you should set the A/B speaker selector to the A position. 

2. Also, you can try to conduct a test tone operation to see if the speakers are working correctly. Go to the surround speaker settings and increase the volume to maximum. Alternatively, increase the volume of the rear speakers and see if it helps.

3. Go to the menu and try to select either large or small for the rear surround speakers.

4. Confirm that the A/V receiver is programmed to surround sound mode. For Dolby ProLogic surround, you can do this by making sure the center-channel mode is set to “Wide” or “Normal”.

If your audio source is a Blu-ray Disc player or DVD, check the menu to verify that the surround sound is enabled for the player itself. Also, the audio you’re receiving should be multi-channel. 

5. Another thing you can attempt is to set the A/V receiver to an alternative surround sound mode. The alternative is to test with a 5-channel stereo mode; if this works, there is a possibility whatever you’re watching isn’t encoded with a surround sound or the A/V receiver is on the wrong decode mode. 

You should note that normal day-to-day programs on TV are generally not recorded in surround sound, so try watching a nice action-packed movie and experiment with the different surround modes. 

6. Check that the source of the audio you’re playing from is encoded in surround sound. Remember that surround sound isn’t always present in 5.1 home theater systems, especially during dialogues while watching a movie. Most of the sound tends to come from the center speaker, with the rear speakers producing audio mostly when there is background or ambient noise. 

If you’re listening to music, note that this will normally be in stereo mode, so the rear surround speakers won’t work. Also, when playing a game or listening to a soundtrack that’s in surround sound, your rear speakers tend to be much quieter compared to the front speakers.

When watching a movie, the rear surround speakers almost never give out the same amount of sound as the rest of the speakers. You can try accessing the menu to adjust the gain for the rear speakers (+/- dB) or adjust the distance between where you’re sitting and the placement of the speakers for louder sound. 

7. If you’ve tried all the above and nothing is working, try resetting the system back to factory default settings. Remember to check the operating instructions for reset steps that are specific to your home theater model. 

8. Once you have reset the unit, follow the steps to calibrate the relevant settings appropriately. Note that after connecting the calibration mic device, ensure that the microphone is placed on a flat surface away from the device to prevent obstructions between the mic and the speakers as the calibration occurs. 

9. Lastly, you can try replacing the wires altogether or connecting another pair of rear surround speakers. 

So, if the rear surround speakers in your home theater system aren’t working, try any of the above possible solutions to restore the integrity of your movie watching sessions!
