I have a velodyne spl-800 it has stopped working when i go to use it it will turn on but won't work it makes a sound but not a bass sound it sounds kinda like a burping noise and has no bass.

SOURCE: Velodyne SPL-1000 II subwoofer only snaps, pops and hisses

Go to the Velodyne web site, look under the support section and check the service center listings.

Also you could try the place you purchased the unit.

SOURCE: JBL PB10 subwoofer, it makes a loud burp noise when it comes on.

In the industry - It is called "Turn-On Thump".

There are some manufacturers that eliminate components like noise filters on enry level lines to save money.

There is no way to lessen this noise without ripping the amplifier apart and having a technical knowledge of the way amplifiers work. It would involve hard-wiring a slow charge capacitor in the turn on line so it gradually builds power instead of getting it all at once.

Thanks for using FixYa - a FixYa rating is appreciated!!

SOURCE: no sound

1. Verify unit is plugged in and power outlet used is active.
2. Is power switch on?
3. Is auto turn on/off set properly?
4. Is unit receiving an input signal from your source?
5. Have all controls on subwoofer (volume, crossover, phase, etc.) been
properly set?
6. If unit has been running at high levels, one of the protection circuits may be engaged.
7. Has the built-in amplifier overheated?

dear "rai17"

This, to me, is most likely the voice coil inside the driver rubbung against the yolk plate, or possibly the spyder slapping the metal plate underneath it, or the amp-(if it has one?) getting tired. this can occur from poor build quality, or playing the subwoofer too loud. depending on how much it cost you, you may want to get it repaired(voice coil re-alignment or something or new amp). But the way it seems, it is probably the driver itself. subwoofers get looser as they break in. This one may have been over-broken....sorry

I hope this helped clarify what is happening!

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.
