Worth repairing JBL L100t3 speakers?

If the sound quality of those drivers were worth it before they stopped working, then I would say yes. And as far as finding a suitable replacement, well that's easy. Even if you can't come by the originals or new surrounds for them. Just measure the driver's electrical properties, then the internal volume of the enclosure and a close replacement could be located at Audio Express or some other online site like that. And usually for a good price as well. Good luck in whatever you decide,

As Elizabeth mentioned, if the woofers are not making any noise at all, the voice coils may be shot. The woofers should move and play even if the surrounds are in need of replacement. I just replaced the surrounds on a nice pair of L100t3's I have, and it ran about $120 for the pair locally. (professionally done). The L100t3 is actually a pretty good sounding speaker for what they sell for ($650-$850 pr. used). Very dynamic and efficient, accurate tone and strong bass. A nice looking speaker too, if the cabinets are in good shape....Don't toss them out!

Bigshutterbug - where did you get your L100t3 repaired? I am in New Hampshire. Thanks.
