Sony Active Subwoofer noise

Subwoofer suddenly makes loud buzzing sound when system is off, and air blows through hole in bottom of sub. Noise goes away when turned off. It comes back later for ** reason. Sub works fine when whole system is in use. I tried unplugging power supply form sub and receiver in hopes of resetting sub, ** luck. Is it the sub or something else.

    I have that same sub with the same problem, but have found the solution. Seehttp://www.sunfire.com/sub_faq.html#set_... and look at "why does my system have a loud hum." The splitter may help some, but only because it is splitting the signal that is causing the problem, that signal will still be amplified, but just not as strong. Try THIS: turn the crossover all the way down to 40hz and slowly turn the volume up from zero. Leave the volume just below the point where it starts to hum/buzz. You can turn the crossover up a bit too. I have mine set at about 80hz and the volume a little less than half way up. It sounds good this way, any louder and the sub is too loud when the speakers are low. With these settings I don't get the hum when turning the receiver off. If you don't like the sound this way you will have to fix your ground/signal problems as stated in the link.

The circuit that should be turning the sub on and off based upon the presence of an audio signal is not working correctly and the sub is trying to reproduce 60 cycle hum. The unit needs service.

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

Why does my car make a loud humming noise?


The buzzing noise is air in the power steering line. The reason it is only one n one side is cause when you turn the wheel it causes more pressure to build. Take the cap off the reservoir and turn the wheel back and forth all the way hold for a second on each side until the buzzing noise goes away. If that don't work then check your rack and pinion system to make sure you don't have leakage or damage from road debris.

KLH subwoofer Model BASSBite V. Has a bad 60Hz buzz


Before you go throwing money at this problem, try to eliminate any external influences like track lighting. I myself am trying to figure out why mine makes a buzz throughout my system when the lights are on. I already replaced the variable light control with no improvement.

Bad cable ground can let airborne electronic noise into the Sub's amp.

Subwoofer problem


If you get your system up and running and hear an audible buzz or hum, the first culprit to look at is either the powered subwoofer or your reciever feed at the entry point to your system.

Loud buzzing from Kef PSW1000 Subwoofer


yes. A good idea. Kill power to the sub, then unplug and remove everything from the sub. go ahead and plug it in again and check for buzzzz.
That is test one. if you have buzz still, its the sub assembly. bad luck, but not impossible. If the buzz is gone its one of the signals to the sub. They can produce a buzzz without any signal coming from your stereo equipment. Replace the feed line, enjoy! BTW...Kef sure does sound clean. good choice.

My Air Conditioner makes a loud buzzing noise now. It didn't do that before, now it makes so much noise I can't hear anything over it


Buzzing noise - contactor. maybe a bug got in the contacts or maybe the coil is bad but in any case if you replace the contactor the buzz will go away.

Subwoofer noise


You didn't say is your sub active or passive.If its active first check signal cables from theater system,power line of the sub, it has to be the same phase as the system.If its passive take a voltmeter disconnect the sub from the system and measure for DC voltage on the SUB output on the system when its OFF.If DC voltage is present your amp is damaged.It can also be that the preamp circuit for the sub doesn't mute the input when unit is on stand by and you hear frequency of your power supply (50-60Hz) on the sub
