    JBL L100 midrange !!!

    hello ! i found a pair of JBL l100 century in a very good price (200euro) but the mid-range speakers look a little different, just like the photo http://www.gophoto.it/view.php?i=htt...g#.Uao3K9jS2Vg

    whats your opinion ?? aftermarket or recone ?

    Sun damage/age difference is my guess. The reddish one looks like it has discolored due to environmental issues. I've seen others that looked that way.

    Just guessing... either one could be a recone.

    They could have been manufactured at different times. Take a look at the label and the color of the tweeter surrounds. The originals were yellow. Latter ones were black.

    Is the one on the left an L100a? If you look closely you can see it has the orange JBL logo whereas the one on the right has the black logo

    You know, I thought about that but didn't look closely enough. I think you nailed it.

    For what it's worth, my L100As (close serial #s but not sequential) have always had their grilles in place except when playing music.
    I have one mid cone that is considerably darker than the other and it's not from Sun bleach.
    And yes, the pair in the photo are two different speakers; one from L.A. the other from Northridge, so definitely mids from two different production runs.

    Yes I can.
    Looks like a little before and after action with the photos too, one with the tweeter foam diffusers, two not so much!

    That degree of difference is about what I have going on as well.

    Is that a Grundig or a Telefunken in the background?

    I think the opinion is they may or may not both be original but even if they are they may not be very closely matched...

    I guess the best case is they are original and the same series but one is sun damaged... still not an ideal scenario.

    There were definitely two different LE5 cone colors. Having reconed many of them over the years using genuine JBL recone kits I can confirm that.

    Thank you for that!
    NOTHING beats "hands on", (I have had this conversation/debate 50 times but had nothing to substantiate it/back it up)
    In all the years you have handled JBL, was it fairly common to see small "blems" in those LE25 cones?
    Common at all in your experience?
    Link a wrinkle almost, but the cone/dust cap absolutely having never been door belled?
    I have seen it more than a few time and one of mine suffers from it, but I know for a fact that they have never been damaged by injury unless it occurred at JBL?
    Just a little deformity and confined to only one spot, NOT a concentric irregularity.
    You can feel the imperfection with a finger; it's as if a small piece of trash may have been on the form when they pressed those little cones.
    Nipple is untouched.
    What say ye?
    Thank you,
    Thomas

    I have seen it more than a few times and one of mine (currently) suffers from it, but I know for a fact (at least with my personal examples) that they have never been damaged by injury unless it occurred at JBL?

    Anyone else noticed this (seemingly) production "flaw"?
    I only persist in asking as it seems very unlikely (to my mind anyway) to have occurred in such a consistent fashion on the examples I have seen with no other signs of mishandling or damage?
    And on every LE25 I have noted this little "flaw" on it was in almost exactly the same spot, to the left of center when viewed from the front.
    Am I alone on this?
    I am primarily interested on knowing how this may have occurred if anyone has any insight or theories more definitive (factual) than my speculation.
    I find it odd that they could "get out the door" from the factory with these little evident "blems". Then again, compared to some of the New England stuff I have handled and seen, they are pristine!
    Thank you all,
    Thomas

    The effects of time and environment on the adhesive joint. The glue has changed colors from clear/opaque to the yellowish hue you see in the photo.
    This change is common (at least I have seen it on many woofers). Some, more pronounced than others, some, not at all.
