Re: Subwoofer has a constant vibrating tone that will not...

I suspect that what you are hearing is the 60 cps of the mains. If the humming sound is coming the subwoofer itself, then it is possible that you have a defective/leaky capacitor in the power supply section of the subwoofer. In the subwoofer, if the buzzing sound is coming from anywhere else other than the speaker itself, then it is possible that you have a loose transformer again in the power supply. Unless you are comfortable working with testers and soldering irons, I would suggest an electronics technician who should be able to diagnose and fix it for you.

Sub Speaker giving intermittent loud crackling and sharp loud popping sounds even with main volume control turned off. Crackling sound can be reduced by turning sub volume control off.

It may be the control itself too. In time, these controls can get dust build up inside it. There are volume control spray cleaners available from Radio Shack or other electronic parts stores. The cheat on cleaning the control is to just rotate it from stop to stop as many times as it takes to clear the noise.

Subwoofer makes noise like an untuned TV regardless of volume knob

I would suggest your crossover unit has failed in the speaker cabinet. The crossover circuit board separates the low and high frequency content of your stereos audio signal. The low frequencies go to the bass unit (woofer) and the high frequencies go to the tweeter speaker. If the capacitor on the crossover goes open or near open circuit then noise is introduced into the sound system. Replace either the capacitor or crossover unit.

Subwoofer is buzzing when volume turned up just past middle level-in other words it doesn't take much for the subwoofer to start buzzing

You may have overdriven the woofer at some stage, and torn the cone. Once that happens, the tear will start flapping (buzzing) whenever the volume is high enough to vibrate it loose.

If thqat's the case, you'll need to replace the woofer inside the cabinet - or replace the set of speakers, which is probably more economical for you.

Logitech Z-2300 subwoofer/Bass volume cannot completely shutoff

Make sure the wired remote is connected completely and if that doesn't work try putting a pillow or a pile of blankets to cover both the subwoofer driver and the air port on it and that should reduce the sound coming from it. Also if it is in a corner or on a solid floor like wood or tile i would move it to a less enclosed space with carpet or a rug. Thats all I got I hope that helps.

My subwoofer on my philips 5.1 speaker system is constantly generating lots of bass noise even on mute.

I assume you are using XP. Try these steps.
1. Open 'Sound and Audio devices' in Control Panel.
2. Select 'Advanced...' button near bottom. b2053f1.jpg

3. Select 5.1 system 972ed04.jpg

4. Start playing a sound.
5. Set the volume control of the subwoofer to the middle position.
6. Open volume control and adjust Master volume to a comfortable level (i.e. until there is no hum).
Also make sure you haven't muted any sound device except microphone. I think your problem is you have set it to the maximum level. So decrease it.
7. Mute the sound and check.
Good luck! Let us know the result.

Subwoofer Emits a Buzzing Tone

The 2200 uF capacitor in the power supply has gone bad and the humming is a 60 Hz from the rectification of AC to 18 vDC.  Either get a new power supply or take apart the power supply and replace the bad cap.

Crackling noise from subwoofer????


i think your speaker cannot support the sound that your computer produce. it means to say that, they are not compatible. specially when your computer sound interface that you used is 5.1 or 7.1 interface but your speaker specs is only for generic sound, you really hear a crackling sound and more if you set to higher volume.

but it can help if you only set your computer interface to generic sound or set only in lower volume it can help. because if you continue that way, your speaker can be seriously damaged that even at the lowest volume can hear the crackling sound.

or if you really want a fine good sound system then, buy a speaker that can interface with 5.1 or 7.1 or see manuals of your computer/motherboard. for recommended specs

Noise from speakers when playing basses


Offhand, could either be the subwoofer speaker itself or the electronics (amp and/or crossover). One way to determine is by physcially checking the sub speaker. When playing with bass on, pls try restricting speaker movement by pressing on it and see if the noise is reduced. Another is to temporarily replace the speaker. You can try speakers meant for the car, home entertainment or book shelf, just dont set the volume too high.

If the speakers are ruled out, then it would be the electronics inside. For this, you would need familiairty with electronic components and circuittry, a DVM and a soldering iron. Access to an oscilloscope and an audio signal generator would be nice but not a necessity. The idea is to inject a constant audio signal and determine where the noise (if electronic) is coming from. In most instances, it would be a leaky electrolytic capacitor either in the input stage or feedback loop. At other times, it would be also a capacitor in the band pass filter.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
