If your LG subwoofer is cutting out or produces a weak or distorted sound, it is likely due to a few different problems. The most common causes of subwoofer cutting out or distortion are as follows:
1. Low Power – Your subwoofer may be running on low power, causing it to cut out or give a weak output. Check that your subwoofer is powered correctly and that you are using the correct power supply for your subwoofer.
2. Faulty Wiring – If the wiring between your subwoofer and receiver/amplifier is outdated or corroded, it could cause the subwoofer to cut out or distort the sound. Make sure all wiring is correct and in good condition, then try again.
3. Subwoofer Settings – Be sure to check the settings on your subwoofer. Many subwoofers have built-in configuration settings where you can adjust the frequency, gain, and other settings. Make sure all the settings are correctly set up and calibrated according to your needs.
4. Amplifier Settings – The settings on your amplifier can also cause the subwoofer to cut out or give a poor output. Try adjusting the settings on the amplifier to see if it helps.
5. Dust or Debris – The inside of the subwoofer may have accumulated dust and debris that’s impacting the sound. To clean it out, unplug the subwoofer then gently remove the dust and debris using a compressed air canister or vacuum cleaner.
Use caution to avoid damaging the subwoofer’s internal components.
If you’ve checked all of the above, and the problem persists, it may be necessary to contact LG’s technical support for further assistance.
What should I set my subwoofer cut off frequency?
The best frequency to set your subwoofer cut off at depends on a few factors like the size of your room and the type of speaker you have. Generally, the frequency range of a subwoofer should not overlap with the low frequency response range of your main speakers.
You should be able to find the frequency range of your main speakers on the manufacturer’s website.
For larger rooms, usually the subwoofer should be set below 80 Hz, as the sound waves above that frequency can bounce around the room and cause muddiness. For smaller rooms, the subwoofer can be set up to 120 Hz.
However, in rooms that are larger than average, 80 Hz can still be used as the cut off frequency.
Other factors that can influence the cut off frequency include personal preference and the design of your speaker. Your speaker may be made in a way that the low frequency response ranges up to a higher frequency compared to other speakers.
Therefore you should adjust the cut off frequency to fit the design of the speaker.
In conclusion, it is recommended to set the subwoofer cut off frequency according to the size of the room, the frequency response range of your main speakers, and the design of your speaker. With this in mind, you can then adjust the cut off frequency accordingly.
