sean5340 Posted March 14, 2012 Share Posted March 14, 2012 I bought some JBLs today. $75 for the pair. Quote Link to comment Share on other sites More sharing options...
sean5340 Posted March 14, 2012 Author Share Posted March 14, 2012 Neither mid-range is working though. Where should I start trouble shooting? Quote Link to comment Share on other sites More sharing options...
djk Posted March 14, 2012 Share Posted March 14, 2012 Rotate the L-pad back and forth and see if they come in. Replace L-pad with 50W unit if bad, recone 2105 (mid) if open. Replace the tweeter L-pad if replacing the mid L-pad, a 15W (the stock size) is OK for the tweeter. Quote Link to comment Share on other sites More sharing options...
Marvel Posted March 14, 2012 Share Posted March 14, 2012 Sean, Replacing the L-pads, working on the crossovers requires carefully removing the foilcal (thin aluminum with the logo), removing two screws that hold the crossover/L-pads against the front of the cabs. The crossover is then removed from the cab after pulling out the woofer. BTW, the woofer is recessed slightly. Once removing the screws you must carefully tilt the cab to removed the woofer. The glue has dried out so much on my 4311s that I can just pull the foilcals off without bending them. Bruce Quote Link to comment Share on other sites More sharing options...
djk Posted March 15, 2012 Share Posted March 15, 2012 Freeze Mist can help make the glue brittle, then use a putty knife. Quote Link to comment Share on other sites More sharing options...
sean5340 Posted March 15, 2012 Author Share Posted March 15, 2012 Thanks for the great advice. I'll see if I can get them going. Quote Link to comment Share on other sites More sharing options...
sean5340 Posted March 15, 2012 Author Share Posted March 15, 2012 Bad news. They tested open. I have never re-coned any speakers before. I do have some Yamaha mids with aluminum cones that fit. I'll try those to make sure everything else is OK. Quote Link to comment Share on other sites More sharing options...
jhoak Posted March 15, 2012 Share Posted March 15, 2012 Check here: http://reconingspeakers.com/products-page/diy-parts/jbl-le5-10-le5-6-le5-8-le5-12-c8rle510-4311-midrange-recone-kit/ There's only one JBL LE5-10 listed on eBay at the moment but they do sho up there fairly often. Good luck. They're definately worth fixing. Quote Link to comment Share on other sites More sharing options...
sean5340 Posted March 15, 2012 Author Share Posted March 15, 2012 Well, these sound pretty good with the Yamaha mids. I knew I kept them for a reason. No modification was needed. I'll keep my eyes open for some replacements but for now I'll just enjoy them. Quote Link to comment Share on other sites More sharing options...
sean5340 Posted March 15, 2012 Author Share Posted March 15, 2012 I can understand why JBL has a loyal following like Klipsch does. Yes they do sound different than the LaScalas. I think it is a good different. Not necessarily better but different. I can't imagine the stock mids could sound much better than these. These are keepers. I don't think I'll bother changing the mids back out. Sean Quote Link to comment Share on other sites More sharing options...
Marvel Posted March 15, 2012 Share Posted March 15, 2012 The mids can break up at higher volumes (perhaps not the Yamaha drivers), but to me they sound like a quieter Heresy II. The crossovers in these mostly let the drivers roll off on their own. I still have mine from '72, and all the drivers still work. I need new foam rings around the tweters, they have turned to dust. Only one dome pushed in on a tweeter (my daughter did that when she was little). Glad you are enjoying them. Bruce Quote Link to comment Share on other sites More sharing options...
sean5340 Posted March 15, 2012 Author Share Posted March 15, 2012 I agree on them sounding like a Heresy. I've heard them twice before and was quite impressed. They are no where near as efficient as the LS but the 3490 has no problem driving them. Really good match actually. Quote Link to comment Share on other sites More sharing options...
Marvel Posted March 15, 2012 Share Posted March 15, 2012 They are no where near as efficient as the LS... or as efficient as a pair of Heresy, either. I used to power mine with my ST-70. Hmmmm... I still have them both. [H]Bruce Quote Link to comment Share on other sites More sharing options...
Cal Blacksmith Posted March 16, 2012 Share Posted March 16, 2012 I have a pair of H1s and a pair of 4311s, running in the same setup powered by a Mirantz integrated. They compliment each other very well and the sum of the two speakers is greater than either on their own, very pleasing sound. The combo is keeping my 45,000 cubic foot shop (30'x75'x20') well supplied in high quality sound. I have had several people into my shop and remark that my sound system in there is better than what they have at home, I think I agree [] Quote Link to comment Share on other sites More sharing options...
sean5340 Posted March 22, 2012 Author Share Posted March 22, 2012 After ABing the LS and JBLs to death the LS are much better. There is something about the JBLs that I really like though. Anyway, I am now listening with both pairs running and the results are better than either individually. I can't quite put my finger on it but I like it.

sean5340 Posted June 23, 2013 Author Share Posted June 23, 2013 Well I'm moving and have sold my LaScalas to a forum member. Bitter sweet. I'm glad a Klipsch head got them but sad to see them go. The JBL 4311's are my main speakers now. These sound really nice and they'll do fine for now. I think I'll try some Klipsch Reference next. 63's maybe? Any thoughts?

Marvel Posted June 23, 2013 Share Posted June 23, 2013 I would have loved your LS, and wanted to at least get a pair for the music room at the college where I work. Alas, it was not to be. I'm sorry you have to downsize, too. The 4311s should serve you well until you can get some Klipsch back in your life. Bruce Quote Link to comment Share on other sites More sharing options...
