Some time around smokers, perhaps?

Every thing is blamed on smokers! (although I agree, tobacco smoke CAN indeed foul things up)
I've seen the yellow glue joints on woofers with pristine white cones, so that's enough empirical evidence for me that something else is going on
May even be the paricular batch of glue
I've have good luck with white Aquaplas woofers and have only experienced small chips on the edges when removing hardened Lansalloy surrounds
I don't think it's anything to worry about

Makes sense.
Speaking of L100 mids; how tightly sealed does the mid chamber need to be? My seal, as far as woofer pressure or turbulence goes (the mid's little chamber or cup) is fine and solid to the baffle and the wires are well sealed at the entry point in the little cup.
These are an original owner pair and the drivers have only been in and out once, but I can feel that those crummy little wood screws wouldn't need much to strip out of the MDF baffle.
I just snugged mine up (a couple not as "snug" as I would like) and counted my Blessings.
Neither of my cabs used a gasket on the mids either.
"OK" or should I try to tighten up those holes or go with some longer screws?
Would they benefit from gaskets? (O-ring seals)
Thomas
All the drivers in my L100's had gaskets. "O" rings on the mid and woofer a flat paper gasket on the tweeter. There are groves in the frames for the woofer and mids where the "O" rings fit.

Hello!
Yes, I can see the groove, but no O-ring.
I do have the proper woofer O-rings and the paper gaskets on the LE25s.
Just wondering if any response is lost on the mid with the missing (never installed) O-ring?
They were never there on this pair.
Don't know if the mid's enclosure has to be "sealed" as in acoustic suspension sealed or just sealed well enough to prevent the woofer from interfering?
Thomas
The mids mainly need to be sealed on the inside can. Sealing the outer flange isn't a huge deal, but it really should be well sealed. I'll wager there are o-rings around that will fit the driver.
Hello,
Yes, I'm sure there are. Problem is sourcing them. I've long ago given up on trying to source little odds and ends like this from JBL. They don't seem very motivated to fool with this sort of stuff.
I would think they would/should be the hollow type like on the woofers to allow for a nice compression seal without stressing the mounting flange, not to mention the lousy wood screw holes.
I'm going to have to reinforce my screw holes too, during this R&R to double check wiring I became aware of the fact that they're starting to get to that point where they're going to stop getting snug soon and just spin 'round and round.
Don't know why they didn't use T-nuts on these. This big grain density MDF stinks for wood screws
Thomas
I know this thread is ancient; doing some research and came across it.
I thought the original LE25 tweeters had the dark reddish orange surrounds and the later black.
When were they ever yellow? LE20 or LE25s?
Or if you're talking LE5-2s I've never seen a yellow surround on one of those either?
Please advise
Thank you
