endover Posted November 3, 2006 Share Posted November 3, 2006 I have acquired a free pair of JBL LX-55 (large bookshelf) speakers that are in very good condition except the foam is falling out of the 10" woofers (so I guess that means they're not in "very good" condition huh?). I've looked on JBL's website and they show that they no longer carry the kits to fix them. I don't want to put a lot of money into these but they they'll work great in my drum room if I can get them up and running. Any suggestions how I can get those fixed? I'll gladly do it myself. Yeah...yeah...I know these aren't Klipsch but they were free. I promise not to put them anywhere near my Chorus'. Thanks! Quote Link to comment Share on other sites More sharing options...
Guest " " Posted November 3, 2006 Share Posted November 3, 2006 10 inch refoam kit is about 30 bucks plus shipping per speaker on ebay. When you consider the time, chemicals, and the learning curve to ramp up a successful re-cone effort, might want to also look into replacement 10 inch woofers.

Daddy Dee Posted November 3, 2006 Share Posted November 3, 2006 http://speakerrepair.com/ I've used these folks before with good results. Prices are good, I think. The key issue, of course, is the value of the repaired woofer relative to the cost. They also sell parts, for DIY projects. Quote Link to comment Share on other sites More sharing options...
Dale A B Posted November 3, 2006 Share Posted November 3, 2006 I did my first re-cone job last year on a pair of Boston Acoustics A100's. Got my repair kit from PartsExpress, but there are other sites that i've heard of. I spent $30 and was very happy how they turned out. Now I've got a pair of OHM C-2's that I want to get done by end of year. My favorite site for audio related info is audiokarma.org, which I visit daily (along with Klipsch of course)! Good luck!

rcarlton Posted November 4, 2006 Share Posted November 4, 2006 Re-foaming your speakers is kind of fun. Main thing is the satisfaction of knowing they will last another 10 to 20 years. Quote Link to comment Share on other sites More sharing options...

I was with him when he bought them new in about 1991. They were about $750 back then. They are not L100's but still pretty good speakers. Our local DJ Supply shop will refoam speakers for about $50 a pair and he supplies the foams. I always clean off the old foam and bring him the drivers. You will enjoy these, they do very well with SS withotu sounding harsh. Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted November 5, 2006 Share Posted November 5, 2006 Here is the schematic: http://manuals.harman.com/JBL/HOM/Technical%20Sheet/LX55%20ts.pdf If you like these, you can use cheap Dayton caps bypassed with Audiocap thetas. I did a pair of L100T's and they sound very nice. Chris Quote Link to comment Share on other sites More sharing options...

arfz28 Posted November 6, 2006 Share Posted November 6, 2006 I refoamed a set of realistic Mach One speakers for a friend of mine almost 2 years ago and they turned out very nice. I shot a bunch of pictures of the project while I was doing it and it might be some help too you, it was actually my fist refoaming project. Do a search in the Update And Modification Forum. Type in (Refoaming a set of mach one woofers) this should bring you too the thread. Quote Link to comment Share on other sites More sharing options...
thepathlesstaken Posted November 6, 2006 Share Posted November 6, 2006 They don't need to be re-coned (thats replacement of cone, voice coil and spider) but rather need to be re-foamed or re-edged. It is a pretty easy task and enjoyable if you like to work with your hands. I have refoamed 40 or so speakers so far. Here are a few tips: 1) I use a highly bright light on an end of a flexi stalk in order to heat up a 3" area where the foam meets the cone or basket so as to make the glue more pliable. Some glues don't take well to this but the majority of them do. 2) Use a drimmel with wire brush to clean up the basket / foam contact area afterwards if there is lots of sticky residue. Regardless of the residue you just might want to scuff up this area with light grit sandpaper in order to make the adhesive stick better. 3) Shims work fine but you can also do the work sans shims even with highly efficient speakers (smaller voice coil gap). I have done two Cerwin Vega re-edges sans shims and they both have come out fine. 4) The milky white glue that most re-edge kits come with SUCKS because it is hard to work with (takes 5 minutes to setup). Go with kits that supply the orangish / yellowish glue. 5) Orange County Speaker repair is a very legit company for re-edge kits. You have to request the orangish glue though with some kits. They might have stopped offering JBL kits as I think that JBL wants to start doing all that stuff in house now or something (think I read this recently).
