Question about Velodyne DD-10 Subwoofer

Crackling coming from Velodyne DD-10 subwoofer

This started as a small problem a few weeks ago whenever I powered the sub on, then would go away in about 5 seconds, and the sub would play fine. Last night, the problem worsened as the sub actually crackled and distorted with program material playing through it. It isn't constant, but occasional. I'm VERY irritated, since I didn't expect this from a Velodyne sub. I have a second DD-10, and I switched the interconnects and power cords betweem the two just to make sure it is the one sub that is the problem, and it is. Any thoughts?

    I'm hoping that isn't the case. The person I spoke to on the online change said he is sure it's not the amp, but something with the driver or voice coil. I'm hoping it's that rather than the circuitry or amp. I will call Velodyne to ask them about it. Thanks much for your input!!

    Easyq, turns out you are probably correct. Just talked to Velodyne rep, and he is certain it is the amplifier going bad. And actually according to him, that is much cheaper than if it were a driver, so I was wrong assuming that the driver would be cheaper to replace. Thanks for your input!

    Yes, so I was told by Velodyne. Support person is sure it is the amp. Unfortunately, I purchased this on Audiogon a year and a half ago, and Velodyne won't transfer warranties, a practice I don't agree with. Would be nice if there was an option to purchase a second-hand warranty, or something like that. Anyhow, I was told the cost of repair and shipping back to me would be $240. Such is life! I will let you know when I receive the unit back, and if that truly was the final resolution. Thanks!

Velodyne is known for good service, i think in this case it is best to contact your vendor and have it solved.
I think internally there somethign wrong with the electronics, most likely the amplifier.

    Be glad it's the amp. Drivers used by Velodyne are quite expensive because they're not standard drivers. Can you keep me posted on this as i would like to know if it indeed was the amp and how Velodyne solved it.

SOURCE: Crackling coming from Velodyne DD-10 subwoofer

One of 2 things is going on.

First, the servo mounted in the driver may be going bad or is picking up some noise.

Second, Something in the amp section is going bad, hard to pinpoint the exact problem.

you say that it plays, so I tend to think it is the driver mounted servo unit.

If it is within the warranty time, take the unit back to the retailer you purchased it from, if not contact Velodyne for repair.

One of the bottom aluminum and rubber feet on which the subwoofer sits has gone missing, where can I get hold of a replacement Thanks


Unless you contact the parent company its close to impossible to get that feet. But you can buy a set of four rubber feet at any hardware store and replace them all.
The feet come off when one tries to push a heavy sub like Velodyne instead of lifting it off the floor and placing them . The rubber grip is so good on the floor and when we push the top part of the Sub the feet rip off.

I get a buzzing noise whenever the sub is powered on and connected to the preamp. Tried it on several amps; same result.


You might have got an earth lead loose. If that is not the case then I would suspect an Electrolytic Capacitor somewhere. These are easy to replace and don't tend to cost a lot.

I hear noises when DD-10 is turned on.. even without signal to i


If it is a low level white noise, you may have some form of RF noise that is being picked up by the driver mounted servo system.

Then it could be something else as well.

Best to contact Velodyne to see about service for your unit.

Velodyne SPL8R - same problem...


The first thing to do is unplug it, then pull the sub out of the cabinet, then pull the amp out of the cabinet. If you can take out the amp w/o taking out the sub, great. If there are any exposed printed circuit boards, look for dust buildup. Sounds like you've got alot of static energy built up in the internal electronics. If you have to disassemble the casing to get to the circuitry, do so, just do it carefully. Look at the boards. If there's alot of dust, get some printed circuit board cleaner.(pcb) cleaner found at Radio Shack. Then spray off the boards and the subs volume control as well as the crossover control. This will Not hurt any electronics.Re-assemble and test. If you still have noise: Take a careful look at the input side of the amps circuits and traces, if you have a magnafying glass it helps. What your looking for is a bad solder joint. You will see all the little dimples on the boards from soldering at factory. When you look at the solder point, look for a circular ring generally midpoint on the solder or right at board level. This can take some time, however, it's free and it's more than likely the problem. To fix a cold solder joint you need a fine point solder gun, just touch the point that is bad and it will re-seal, then test. Plug n Play. Hopefully it's just dust and you don't have bad solder joints. Velodyne makes an awesome product!, very rarely do I see problems with them. If you need some more help with this, post a comment and we can dig further. Hope this helps

SPL8R Velodyne sub - Same probelm


Go to the Velodyne web site and check the service center locations.

They may have one in your area.

It sounds like the amp may be the problem. That may be all you need to send.

Best bet, Contact Velodyne.

Major buzz/Humming sound coming from my subwoofer


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.

Dd-18 no sound coming from it...


You could try disabling the auto-on feature or you could try a factory reset or firmware upgrade.

Swap the wires between subwoofers to see if its the wiring.

If its no longer under warranty you could try swapping the amp modules or the fuses, this will tell you if its a fuse or the amp or the driver... however by doing this you risk blowing up the second working amp or voiding warranty.

Last year I had an amp failure on my velodyne and it cost 250 for a 2007 replacement.
