The bass of my wowee one doesn't work anymore


The problem is most likely a broken solder connection on the the voice coil side of the bass transducer. I just repaired one and it was a 5 minute fix if you have a small soldering iron. Carefully pry off the glossy plastic cover where starting with the side the speaker slits (grill) are. It's just held in with some sticky adhesive (peel it up slowly, allowing the glue to separate without cracking the cover). Below that cover are 6 phillips screws. Unplug bass transducer's wire harness from the circuit board. IThe white connector comes apart with a small tug. The other end of the wire harness goes to the round, green transducer's board which contains the voice coil. Remove the transducer assembly (the round thing with with the clear Gel like substance). Carefully remove the gel surround and separate the round circuit board from the round magnet. One of the black or red wires will probably be disconnected. This is probably due to the a bad solder connection coupled with the constant vibrations. Simply re-solder the connection and re-assemble and you're good to go. When re-asembling the transducer, be sure to install the round board first and make sure it slips UNDER the raised lip inside of the Gel. If installed correctly the whole bottom of the round green board will be in full contact to the gel. Now install the magnet. The magnet should rest on TOP of the gel lip inside, the lip keeps the magnet raised slightly above the board and allows it to vibrate freely without touching the the round board and the voice coil (brown colored wire winding attached to green board. Hope this helps.

I have velodyne hgs15bg powered sub.. After a prolonged hard run, it developed a rattle at mid to higher volumes. what went wrong ??


You possibly ripped the woofer cone or welded the voice coil - something mechanical. There's only one thing in there that moves on purpose.

My subwoofer keeps poping and then stops working


larryagross,
Sounds like you blew the speaker! The amp is sensing the voice coil is connecting to the speakers magnet or iron core and is going into a safe mode. It is possible to blow the coil even when the sub has a built in amp.

First make sure that you have the gains properly set ans not all set to their maximums. Second, disconnect signal to the sub then unplug the power for a few minutes. Third, plug the sub into a source of power on a different circuit using a surge protector.

Does the speaker make any popping at the time it powers up? If so you have a amp problem. If there is no sound produced, connect it back the the system using a different signal cable. Does the speaker now pop again when sound is produced. If so the speaker has failed. Contact a Velodyne repair facility.

Velodyne model spl88v will only make a high pitch chirp used to only happen at turn on now wont play


Could be one of two things.

The speaker could have a rubbing voice coil, that was the "chirp" sound

Over time, this will damage the speaker. If it shorted, then it may have blown a fuse in the amplifier section.

Any good electronics shop should be able to fix this for a reasonable cost. You also could try the place you purchased the unit from.

You could also contact Velodyne.

Extreme distortion with Velodyne SPL 800II


Woofers are subjected to relatively high degrees of acceleration which can cause a poorly built voice coil or spider (an additional support located at the junction of voice coil and cone) to break away from the cone or the surround at the edges of the cone may have dissolved. Cigarette smoke is death to the common foam-type suround and once it is no longer intact, the cone can slap on the frame edges. 
Only the very expensive band/concert-type speakers are worth repairing. Check on eBay for the right size replacement; they atart below $20 US.
High quality speakers actually come with a warranty but then, the Chinese company that built them may not outlast the warranty.

Woofer,s outer ring is ripped.


To fix this problem, you will need to contact Velodyne.
They may be able to replace the surround or recone this driver.

Because this system has the "servo" control, you need to have the accelerometer conected to the amplifier. With out it, the amplifier will not operate.

The driver has a soft foam rubber gasket behind it. It can act like glue on the driver.
Taking the driver out will tear up this gasket, always does, so don't worry about that.

You can try to lever the driver out. Use care not to scratch the baffle.
