I regret to inform you that it sounds like the velodyne's internal amp has a problem and will likely require servicing.

SOURCE: No sound for Velodyne ct-100 sub woofer

Sounds like a dead amp. You could check the xformer output and the amp IC's with a VOM.

These amps do not cost a lot, about $40.00. and are easy to replace.

SOURCE: i have a velodyne va 907 8inch subwoofer it has a

I have the same sub , and noticed a smilar problem. However , mine was traced back to one of the micro-switches on the back side. Apparently , the slide contact on the switch will not stay in the closed position. But when I put pressure on the switch it will come on .

This was found after a period of about a year of the sub just giving us a random , and ever more frequent "bump" or "boom" from nowhere. Apparently the switch would just decide to make a connection. So this may be another place to look at. Click the switches back and forth, and see if you notice the sub "powering up" or sporadic noises.

The volume control pot can be replaced.

Any good quality audio shop or electronics repair shop should be able to fix this.

Get an RCA Y-adapter to feed both INputs on the sub. Define the sub in the Denon and set your other speaker settings as required to redirect the bass/LFE if they can't handle it.

I have a 2002 Velodyne SPL10BV. I used to leave it on all the time because on auto it would cut out. It would come on late when watching a movie. Like the signal was delayed to the sub. Now the sub...


The problem is in the amplifier section.

This sub uses the same amp the HGS units have. The pre-amp is a lot like the HGS units as well.

The only place you will find to service the unit will be Velodyne.

My guess is that you will need to send the amp section to them.
It is easy to remove, just make sure to mark the speaker leads before you remove them.

For the auto on function.

You may have a low signal to the sub.

If your source has adjustments for the sub output, try setting it up a number or two. Then use the volume control on the subs amp to mach your main speaker volume.

Sub seems to not get louder with volume increase. It seems to be overpowering at low volume or boomy then as you increase volume the front main speakers seem to take over.


Try adjusting the frequency cut off of the sub and also play with the gain control on the sub. Turn your system up to where your front speakers are sounding as you like. Then try adjusting the sub to match the fronts so you have a good balance and blend.

I have a velodyne va 907 8inch subwoofer it has a little volume going through it even though the volume is cut up could there be a blown fuse or some other known problems


It could be anything from a blown fuse to a defective coil in the driver. This is strange because velodyne subs are amazing!! I would suggest to wiggle the volume know a little, if that does not work then look for an external fuse on the back of the amp. if you cannot find one then things become even more compliicated! try these things and let me know if it works for you!
Good Luck

Speaker would push out and stay out with a hum when turned on.


Sounds like the "servo" on this unit has gone bad.

You will need to contact Velodyne for service on this.
It is the only place to get parts and service for this unit.

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.
