Need advice on where to send L112 woofers for repair...

[tista]

As title states - just bought a pair of L112s and one of the woofers has a buzz in the lower corner upon significant excursion. I plan on rocking these speakers pretty hard and want to be sure woofers are up to snuff.

So? Who do I send them to? Great Plains? Simply? Someone else??

Any experiential advice is helpful and appreciated as always!

Thanks and happy new year to all.

Hey - You're in NYC area, embarrassment of riches. That is an easy woofer to do, my local JBL guy did mine in a day. Just check for a near-by JBL pro shop. There is a map / service# on the JBL pro web site.

Have you done any investigation into what the issue might be? In most cases a woofer repair requires little more than a re-foam. That is a pretty simple repair overall. If the foam is still okay, and it's some kind of deeper problem, then I might suggest being a bit more picky on who you take it to.

If the foam is okay, the next thing I would suggest checking would be the spider. The spider can become partially unglued/detached. That could easily account for the buzz you are hearing. If it only partially detached from the frame, as shown in the previous linked picture, that means you've averted disaster and all it would take is a tiny bit of glue to fix it - no need to send it in for repair.

Beyond that, I would check for voice coil rubbing. If you press in on the cone, is it smooth or does it feel like it's catching/rubbing/grinding on anything?

Re your post #11: Good example why JBL does not recommend re-foaming surrounds. It cannot be guaranteed "as new." The job I referenced above with 1-day turn around was a full JBL recone. Cost approx $220 parts and labor.

Hi there. I went to the JBL pro site and spoke to someone who suggested I send them to a place in Springfield MA. OK, maybe. For my edification, Mannermusic, can you tell me exactly where you sent yours? I'm thinking of just getting both woofers re-done for peace-of-mind, steady listening.

Resuspension with new surround installed cleanly, new spider, replace rotted dust screen, clean gap of foam goo...

They'll perform like new.

There is a couple of videos on my Facebook page of this exact operation I did a few months ago. I should upload to YouTube...on my "to do" list.

Yeah, good thinking. They will last 40 years. The shop here is AFP Sound Systems, 127 N. Wixom Rd., Wixom, MI 48393. 248-669-9900. Forty miles NW of Detroit. Ck the www. You could call for a quote. But, I'd call Springfield first - shipping is not exactly cheap. Mike

Thanks for the replies. I haven't removed the woofer yet. I'm proceeding cautiously and deliberately. Got these off of Ebay and personally picked them up. They looked perfect (common story, right!?), but when I finally hooked them up, I gave them some time to warm up and then I pushed them a bit and buzzo. I was so disappointed. BUT, the seller has agreed to pay for the repair. I just want them perfect because they are kind of my current grail - the ideal upgrade from L100s.

I'm going to reach out via the JBL Pro site and also wouldn't mind some feedback about simply speakers total rebuild service - which I'm leery of due to the cone replacement not being a JBL part.

Again, thanks for the advice - I will take the woofer out and take a look before I go crazy. The foam surround look fine, for the record.

The coil doesn't seem like it's rubbing - no scraping or grinding.

Other diagnostic info: on the suspect woofer, when played at relatively low volume, if you but your finger gently on the lower left corner, it immediately causes sonic turbulence, rattling of sorts. This doesn't happen on the other woofer, or anywhere else on either woofer. Also, when you gently tap that area, the sound is not a solid dull thud, but a slightly 'broken' thud, if that makes sense. Obviously I gotta take this driver out. !!!

From my experience edgewound at Upland Loudspeaker Service operates at the highest level of honesty and integrity when it come to bona fide JBL repairs. I understand he's on the other coast however there would be no questions as to the authenticity of the repairs.

Edgewound may be out of the business / another LHF member has had some 128H woofers waiting for a few months ( for service ) all the while with Ken not being responsive to the owners emails .

So one wants to be careful ( at this time ) making these recommendations .

Not out of business. Been busy...and recovering from colds/flu for the past couple of months. The best way to message me is via email or telephone. The 128Hs in for repair...with JBL C8R128H recone kits will be shipping soon...when the invoice is paid.

BTW....Happy New Year!

Happy New Year to you—and everyone here!

Glad to hear you are still in the game! Good luck in getting caught up, and may we all have a wonderful 2020!

Just this day packed and shipped off my 128H woofers for my L112s to Ken. I'll post up when they're done, back and pumping out sound. Glad to hear your positive experience! It's a long and expensive trip!!!

[DerekTheGreat]

Awesome. You will not be disappointed. And boy do I know all about that expensive journey.. For what I've got into these L150A's, I could have nearly had JBL XPL-200A's or L220's... I never thought I'd be able to jam these L150A's either, every time I got them back from the other "reputable" & "certified" reconer it just got worse and worse. I cannot thank Ken enough for rekindling my spirits with these JBL's, I've been nothing but smiles ever since I got them back on the road. Those Klipsch Cornwalls are trash by comparison, they'll make a great garage speaker.
