Question about JBL PRX518S Subwoofer Speaker

Open Question

We just purchased the second set of JBL 518s and again we encountered the same problem we had with our old set, which is that during use with a DBX driverack, the unit turned off and would not power up. We had them repaired by an authorized dealer and the crown amps were changed. The old units do not seem to have the same power anymore, but now one of the brand new subs has gone bad also and it will not power up. Any advice?

    The driverack is a plus if you are using it correctly. Make sure you are not getting static from your mixer or any other source. If you hear popping in your equipment when you increase the volume it can cause serious speaker damage. Do not try to shack the roof with your subs, relay on your driverack to set your gain correctly. sometimes the accoustics in a room will not give you the sound you are looking. So please rely on your driverack in these situations. Sometimes you have to purchase professional grade speakers to get that professional grade sound. Sometimes you have to add a additional sub instead of maxing out your subs.

Jbl eon 518s power trip on stabilizer/transformer

hell no thats a fire hazard.. I am thinking that the surge is more that that unit can handle..surge is the extra power needed to start up an electrical piece of equipment..surge can easily double the amount of power required for startup..may need a new powerstrip with a much heavier rating..

My bass cuts when playing but goes back on after a few seconds.

that because you have a loose ground to your amp or not the right size wire but check your ground on the amp it will overheat and turn off to protect itself .

We have the jbl eon system. Our subwoofer (518s) is having issues. It will turn on, recognize a signal -even limit a signal, but No sound comes out

First thing is to use an ohmmeter to check the voice coil of the speaker to make sure it is not blown open. After that it is into the shop for amplifier repair.
