Generic problem for all Home Theater Speakers and Subwoofers
Buzzing Cerwin Vega LS-12 Subwoofer (by 5 users)
posted by Vince3962 on Nov 27, 2007
There is a constant loud buzzing when I turn my subwoofer on (regardless of whether there is anything playing). Any thoughts on how to fix it?

Great

Great thoughts. I did as you instructed. Unfortunately, the loud buzzing sound remains. The buzzing occurs anytime the speaker is "on," regardless of whether it is even plugged into my receiver.

Hi.
I had the same problem. It is most likely a bad ground in the home wireing. A temp solution is to stop the ground connection in the 120 input to the sub. you can do this by putting a non conductive like clear plastic over the ground prong and slide the plug part into place. I did this and it works well. Just need to get the master electrician over to fix the bad ground in my breaker box now.

Loud buzzing noise coming from the subwoofer even when the television is off. I must turn off the speakers to stop the noise.

MasterGenerally, a buzz from your sound equipment indicates some sort of nearby EMI. The normal culprits and.or possible fixes that I've found are:
- Remove any other electronic devices plugged into the same outlet as your subwoofer
- If the woofer is on a power strip/surge protector, remove it and plug directly into the wall
- If there are any nearby wireless devices (cordless phiones, WiFi eqiupment), disconnect/power down them
- Try connecting different speaker wire between the woofer & the receiver
- Try turning off all other eletronic equipment with the exception of your receiver
Let me know if any of these help and good luck!

Maybe this might help? It's a quick story of a similar problem I had with my amplifier speakers:
Back in high school, I used to play electric guitar. One day, I noticed a low humming that seemed to become more & more apparent as the days went on.
It eventually got bad enough that I took apart the amplifier. After some visual examination, I noticed a wire whose insulation had melted away from resting against one of the vacuum tubes during operation.
Upon wrapping the faulty sectionin electrical tape and powering the unit back on, I noticed (to my delight) that the humming was finally gone.
Good luck!

Apprenticei also had a problem with buzzing on my eltax atomic a8 weather the amp was switched on or off.
i followed many solutions and the one that worked was isolating the earth pin on the plug.
now not even a hum

If it's not interference or a ground problem it might be a bad amp. I have the same sub and not only did I have the buzzing, but also a noticable "whacking" sound instead of smooth bass. I found an online seller who at the time just happened to have obtained some surplus Cerwin Vega amps that fit perfectly. Paid $60 shipped. Problem solved.

There is too much electrical feed back coming from your earth, you can install a line level filter, or get an electrician to do it. Or you can remove the earth pin on your subwoffer.
I have done this to many subwoffers and it worked every single time.
