Well there are only a few reasons i can think of that just might be the reason behind said buzzing.
1. It may be connected to another power source ( amplified or powered supply ) or incorrectly connected. It may also be too close to said power supply.Try letting the dog (sub) out on his leash a little Drag out the manual that came with the sub, and check the correct procedure for your type of setup.
**People do read manuals still don't they ?**
2.The only other problem i have heard of is port noise in low registers. Keep the the port area clean, as it may suck up dirt, or even worse, small children!
3. However, if you're considering placing this subwoofer in a cabinet, I'd recommend allowing ample breathing room for the heat sink. This can also be done by drilling smaller holes in the cabinet ( 8-12 mm holes - with the owners permission of course) but please do remember to keep the port area clean.
4. The product ie: Velodyne DPS-12 Subwoofer, came with a bad power supply, presuming it is new, check your warranty.
(not very likely - see also scenarios 1, 2 or 3.)
Velodyne has been making subs forever and do it well.

Look for the sub pre out on the back of your amp and connect a sub cable to this and next to the LFE or phono type input on the back of the sub ,if it has two inputs left and right pick the left side ,set the cross over to suit your system and speakers,if you are not sure set the cross over to 80 hertz,this is a thx standard.
hope this helps.

You did not state what model this is.
If it is a servo controled unit, you may have a problem in the control circuit.
The models that use the servo control stystems should only be serviced by Velodyne or one of the listed service centers.
Velodyne is the only source for parts for these units.
