My Velodyne CT 80 powered subwoofer does not power on?

Velodyne CT 80 powered subwoofer with 8" subwoofer

Posted by on

  • supercraig Sep 03, 2008

    Just bought the Velodyne CT 80 powered subwoofer used off Craigslist. I think it was manufactured between 2000 and 2002. The unit is in cosmetically great shape, suprisingly for it's age. Subwoofer looks to be in New condition! The man I bought it from said it was working and then one day he went to turn on and nothing! So, I decided to buy into and fix the problem somehow, need some help as I am not an Electronics Technician. Any suggestions or help would be appreciated.

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.

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.
