This is embarrassing. I need to remove the woofers from my JBL L112 system
to re-foam them. But I can't figure out how to get at the inside the
cabinet.

There are six screws on the back panel of the cabinet that I think hold the
crossover network in place, but there are no screws on the front baffle
except those holding the drivers in place.

Do I go in from the back of the cabinet, or just remove the woofers from the
front? I'm don't want to blindly remove screws and have something fall off
inside the cabinet.

Any suggestions will be most welcome.

Thanks,
Art Harris

If the woofer flanges are on the outside of the cabinet (on
the front panel where you can see them), then just set the
cabinet on its back (with the speakers facing up) and remove
the screws. Nothing should fall off and you should be able
to lift the speaker off the front panel.

There might be some kind of material used to seal the gap.
I don't think JBL ever stooped to such depths, but many of
us use RTV to seal around speakers. In fact except for very
large and heavy speakers, you can use nothing but RTV to
both seal and hold the speaker in place. Easily removed by
running a knife around the bottom to break the seal.

Yes, the flanges are on the outside. Are the screws holding the speakers in
place wood screws? I was afraid there might be nuts on the back of the
screws.

Thanks for for the info, I'll give it a try this evening.

Maybe. But it doesn't matter....

Even if that happens, you can retrieve the nuts and replace
them with "T-nuts". Chances are that if they are machine
screws, they already have T-nuts on the back of the panel.

It's an L series speaker. Do you really think it's worth the
hassel? If so the components inside will probably be of such tookey
construction that replacing the whole thing will be far easier and
less expensive unless you plan to refoam it yourself.

You were right. "T-nuts" on the cabinet. I took the 4 machine screws out and
with just a bit of prying, the woofers freed right up. Thanks!

I think all "real" JBL speakers use T nuts.

I sure as hell would fix an L112 if it just needed new surrounds.
You could expect to pay a LOT more for anything new with better
construction.

(And PLEASE send me any L250Ti's that you want to toss out because they need
new surrounds :-)

Quite probably so.
