I have a JBL E-130 that sounds very good hooked up to my Twin-Reverb. I was playing and there was sudden silence, I mean, no background hiss, nothing. I instantly jumped up, noticed that the pilot light was still on the TR. I shut it down. Went and got another amp, hooked up the speaker, this time played 45 seconds instead of 3 minutes to find the same thing occur. When it works, it is so clean and clear, I'm amazed. It seems sudden and intermitant? help, can I fix it?

Rick, take a VERY close look at the wire connectors on that speaker. Look very closely at the way the flexible wires from the speaker cone itself connect to the connector posts. See if there is anything loose in there. The phillips screws may be loose at the opposite end of the push-button end of the posts. Those screws hold the speaker cone wires on there.

They look OK, But I will check them, and resolder the leads and sand the connector-hole. Thanks!!!

| I had a speaker where the leads on the cone going to the coil had crystalized. I carefully resoldered them and the speaker started working fine. If the coil were malformed or burnt it wouldn't have sounded very good. |

I had a similar thing happen with the BW I put in my twin. In the end I determined that I had left too much wire exposed at the connectors and the two strands were occassionally touching, especially after the amp had been moved around a bit. Once I wrapped the exposed parts of the wires in electrical tape the problem went away.

It has been my experience that speakers sound the very best in the two to five minutes prior to failure. We played an outdoor festival in Kansas several years ago. The warm up band was using our equipment. My bass player and I were listening out front and both commented how good the bass guitar sounded. Very shortly thereafter the Sunn reflex bass cabinet actually erupted in flames!! Looked really cool, too. Of course the warm up band did not offer to help pay for the new speakers...
