    I have a buzzing on the sub woofer which gets louder when I turn it up. I have disconnected all the speakers and tried the box in a different location but it still keeps buzzing. Can any one help? My local electrical shop is not interested.

SOURCE: 100watt sub

There is a problem wwith teh power supply or the amp section. Does the noise remain constant or does it vary in volume? The sub should have a level control, does the noise vary with that control?

SOURCE: No bass...

One of a few things.

The fuse inside the amplifier section is blown.
The amplifier has died
The speaker is dead.

Best to return to the place you purchased the unit or contact Velodyne for service.

SOURCE: sub woofer buzzes all the time

ur sub wont buzz due to bad speaker. either u have a faulty preamp or power amp. yes it can be repaired and will not cost much. if it is loud and annoying, get it repaired. sometimes subs emit low hum when powered up. this is the way the are desinged.

If i increase the sub woofer volume the voice distorts and gives a buzzing sound. it works fine on low volume

Your sub woofer is not mean for voice sound...check that you have connected the systen up properly and that you have put the sub woofer into its wn connection..if it is in the right connection the woofer could be blown.also try decrease the midrange hurts on the woofer

Kef Kit100 subwoofer buzzing

You have a bad set of Audio output IC's for the sub. There is two of them. TDA7293 REPLACE BOTH!!!
There is 4 on one side of board,and 2 on other "also 1 small one" The the two are for the sub,the other 4 are for the main speakers/surround. They sell on Ebay for $6-10 each or a kit of all 6 for $25.

Buzzing sound from woofer when I plug in

If the woofer works fine when plugged into any other port, I would say that you have a connector on the receiver that has a loose connection or possibly a cold solder joint (poor or broken solder joint). RCA jacks can be stressed quite a lot especially if you use cables that have very tight connectors. The female RCA jack gets wiggled or twisted when trying to remove a cable and this causes solder joints to crack. I would have a look at that connector on the receiver..

Jvc rx-e100rsl home cinema control center

unless there are some other connectors that may be used, i would think that the issue would be resolvable thru the system settings menu, there may be a speaker arrangement setting somewhere in the menus. The Sub is a .1 setting like 5.1 or 7.1, perhaps even 2.1 where the beginning number is the speaker channels and .1 is the sub. I would think with the sub being on a mono channel it woul/should work with any setting. If there is any more info you could supply I will further research this issue and try to help you get the sub working.
