I just repaired two JBL 128H Woofers on my set of Jubal L-65s. I used the Foam Edge Kit I obtained recently from Simply Speakers. These loudspeakers are extremely important and precious to me. I've owned them since the mid 1970s and they are truly my "EARS." The woofers had been "re-foamed" in the late 1990s by a professional repair facility. Recently I discovered that both woofers needed their foam edges to be replaced again due to the onset of deterioration. I owned and engineered a professional Multi-Track Analog studio in Philadelphia which sported JBL Studio Monitors in all its "live" and control rooms. The L-65 speaker system I own was always used in my residence. They serving as the perfect pair of "test" speakers outside of the studio environment. The foam edge repair restored these woofers to perfection! I am thrilled to have my "ears" back at 100%. Thank you Simply Speakers for the terrific video, which I watched several times before making the repair to both woofers last night. Messy? You bet! But worth every bit of cleanup to have my Jubal L-65s singing again! Deeply appreciated!! Andy Kahn
Those are awesome speakers. I will surely buy a pair of these when I find them locally.
Ordered a kit from Simply Speakers for my JBL LX 44s. I live in Arizona and the delivery of the kit from Florida was ridiculously fast and free. I spent a lot of time cleaning the old foam but it was worth it. The new foam parts fit like a glove. Everything went just like SS said it would. I am so happy with the results that I decided to write this review. Thank you Simply Speakers for saving my JBL LX 44s. Just listened to some Zeppelin, Steppenwolf, Allman Brothers and James Taylor and wow just wow. Now I know why so many people are into these old AMERICAN made quality built speakers. Repairing them reminded me of working on an old classic muscle car. Quality.
Lancelot Link omg. I just ordered from them and I too live in Florida and it got to me in 2 days!! They really are on top of things ;) removing that old adhesive us quite tedious...
I currently have a pair of these and I like them. I will buy a pair of L-65 as soon as I find them locally. I love the jbl sound.
Most thorough and well explained instructional video I've ever seen, every detail covered. I'll be soon refoaming a pair of 128H's just like these with confidence.
Thank you!
First time repairing anything related to speakers and it went off without a hitch! Awesome and easy tutorial. Thanks for the kit and video. I will definitely use you guys again!
Thanks so much!
You make this look a lot easier than it is!
I just finished putting new foam on my JBL speakers, watched this video as I was doing it. The kit I ordered from yall worked perfect! Was very easy! I am now enjoying loud, crisp music again! Thank you for what yall do!
Great to hear!
You are well practiced at this, thanks for sharing your knowledge.
Great video!! I have watched several videos before attempting and this and you really made me feel at ease.
Great how-to guide, can't wait for my repair kit to arrive.
Ordered the kit from SS and undermounted the surrounds on my >25 yr old 8" JBLs. I skipped shimming the coil to center on one and it made no difference (the coil has very very close tolerance on these - would not accept playing card strips). Both speakers sound better than new. Way worth the $25.
Thanks so much! I’m not very handy but this video helped me save a pair of JBL 4408A monitors.

Hello Simply Speakers
Merci pour votre Woofer Speaker for JBL et votre vidéo très bien faite, qui explique parfaitement la méthode pour rénover mes enceintes de 1980.

Terrific video. I have to repair two cone rear mount foam surrounds and this video will be the bible. Great stuff SS.
Denis Halls Thank you!
Thanks a lot for this video and for a great product!
I wasn't ready to give up on my LX500's. Now they are all patched up and hopefully set for another 20 years. Thank you much!
Thanks!
Would not have attempted this if not for these excellent videos! Great job guys!
Thanks!
Thank you for this very informative video. I'm getting ready to do my L96's/ 8" woofers. I feel like if I take my time and be careful, I should have a wonderful result. Thanks again.
Great video, big help. Doing my JBL 4410's. Thanks!
very good on the demo to do that re foam.......i have used your kits and have had great results, the glue is the best...Bill
Class... #end
It has been repaired , thanks .
Just ordered a reform kit for my vintage JBL first time for me doing this, hope mine come out as easy as the ones you did in the vid.
Good luck!
Yeah thank you guys just finished my JBL MRV308 had to do both speakers, first time I did it, bent up one of the cones a little, but they sound great and I can turn my stereo up loud again. Seemed a little more difficult because the frame was and cone only had about 1 cm of separation so cleaning the back side of the cone was a little more difficult.
thank you. Yes, its not very difficult. Take your time and follow the video.
Excellent love this video
Just about to order my foam for JBL L80t3. excellent video convinced me that I can do it. THANKS!
Appreciate it. Your welcome!
Simply Speakers Speakers came out awesome. Just as good as new!
Hi,, Great video. What sort of glue is that? I was advised to use PVA but think it will be messy.
Robert servande good job sir
watched few few videos on this subject and this site has the best methods and best type of glue and application ,,, he is a very knowlegeable & skilled tech
Just finished pair of 125As from L36s, my 1st refoam. Glue application is harder than it looks here on back of the cone. Glue dries pretty fast so if you dont lay an even bead 1st time, touch up is sketchy. I had to do alot more babysitting the foam to cone curing, bout 15 min of pressing foam to lay down flat & stay there with a spoon handle. Once this Glue tacks. It's hard to work with.
tés bien merci !
Very good instructor.
Thank you!
Great Video. Used this to install my JBL L26 10" woofer surrounds. They look and sound great now. Great product. Fast shipping and great tech support. I would definitely order from them again.
Michael Wong Thanks!
Great videos and work...
Please, do you have the 335439-001 midrange and 335149-001 woofer repair kits?
From JBL S38, maybe S38ii fits fine...
Thanks!
Cabinet model please?
you can tell this guy had done this 10,000x he looks like some who's been on a potting wheel for 30 years.
How did you clean the pulp cone? Mine is dirty
Thanks for that:-)
Great Vid. Do you guys do a Pioneer HPM surround and video?
Not yet....but we are working on more videos all the time!
Mine have cloth and sound excellent
a job well done....nice and clean too
+craneoperator4 Thanks!
I've found that I rarely ever need to use alcohol on cleaning the frames or cones. I simply scrape the old foam away with my razor knife and the foam is removed.
Wow!! This video is 9 years ago? Are you guys still in business? Because I have to re-cone 2 JBL L-150 speakers. Your Logo actually look like the JBL L-150s..
Yep! We have been in business since 1992. Visit our website here:

Hi i wanna do my 118H but the surround is more rubber than foam. Does the alcool will work as well ? Great video.
+Team Sure does!
Bravo
I have a set of JBL 112's one of my Grandkids pushed on one of the speakers and the center cone is pushed in how can I get that back up ?
Try warming with a hair dryer and using a piece of painters tape to pop it back into shape. If that doesn't do the trick, we sell the new caps. Part # DC-3P. See our website. Thanks!
you are the best.
What kind of glue did you use to repair the speaker?
We use our MI-3035 speaker repair adhesive.
hey, I got a pair of JBL 4425 that's bee re foamed but I noticed that it was glued on top pf the cone not underneath as you guys are showing, will this affect the sound? I want to get your foams as they are the best would it be possible remove the ones on top to do it properly with your products? thanks
Send a photo of the woofers to us at: info@simplyspeakers.com and we will take a look to see if you might be able to remove the top mounted surrounds.
Are the standards of the surrounds different for other JBL models? I just finished my 4410s and the surround spacing was very sloppy between the cone edge and surround roll. Bad enough they may need to be reconed. Nothing like my CVs, Advents, or infinity speakers.
Need more info. Send a photo of the repair you made to: info@simplyspeakers.com and we will take a look. Thanks!
Do you have the 335148-001 JBL woofer repair kits from S26BE Studio Series bookshelf speakers ?
Please contact us though our website at www.simplyspeakers.com
fisher also used alot of white cones
Is that 91% isopropanol you're using? It's kind of hard to make out from the video. I tried some 70% (because it's what I had), but it doesn't seem to do much.
Ivan Jager Yes sir. 91%. Lacquer thinner works good too on stubborn speakers.
I just scored a pair of jbl L112 s. free. the foam deteriorated and the owner put out for trash. SCORE. this week I also pu. a nice battery that charged up to 14.volts. another SCORE. I now have a no fuel to engine that's sux
Hi, SS do you send this Foam Kits to Portugal, if i ask you to?
Yes! Add item to cart on our website, then enter your country to see delivery rates.
This took a lot of worries off of me. I think I could do this at home. I need foam edges for the woofers in my 4425.
Contact us through our website for part numbers and prices. Thanks!
i see plenty cerwin vega refoam vidios however not a single comlpete rebuild. im reconing a 15' dx9 woofer and cant find any information on how to set the depth of coil. i dont want to go off its current position do to the fact that someone has already had these apart at one point and time. if any one can point me in the right direction it would be greatly appreciated
Send a photo of the coil shimmed in place before you glue in the spider and we will let you know if you are safe to proceed. Send to: info@simplyspeakers.com
Can you repair the cone if it gets a smash in it?
I’m thinking it’s just paper with a coating.... maybe some light glue and some new coating will fix it.
Depends on how severe the damage is. Contact us through the website. Thanks!
👍🤘
What glue is it?
Our MI-3035 adhesive and it is included with the kit.
Are JBLs the only speakers that have that white cone appearance? Never saw that before...
Tim Richter Not all JBL models use the white coated cones, but many do.
Some Older Fishers and Yamaha's had white cones . My JBL L-100 have white cones
jbl model # l96 ie10h-1
Just like the 128H, except a smaller outer gasket. See our website. Thanks!
