Problem with Velodyne DLS-4000R

[1lakerfan]

When the subwoofer is getting base at low volumes I here a low crackling type of noise. But when there is alot of bass it sounds normal so you cant notice this noise. I am sure it is the subwoofer and has nothing to do with reciever, speakers or setup because when I turn off the reciever and turn on the subwoofer I can hear that little crackling noise when I get close to the subwoofer and listen to it. Can anyone please tell me what the problem is?:(

Hello,
In all likelihood, from your description, the problem is with the bass amplifier portion of your sub-woofer. Low level crackling sounds can often be caused by a faulty resistor somewhere in the amplifier's circuitry. It might be best to contact Velodyne's service department or the audio shop where you bought your sub-woofer.
