    What should I do with these L100's??

    Well I was shocked to get a call from a local thrift store telling me they had some old speakers and receivers. And even more shocked to see they are jbl 100. I paid 13$ for 2 receivers and these L100's. I though the worst thing was the whole in the surround. After I got home and cut off the shrink wrap and bubble, I see more problems. So to list the problems, missing grills, grill anchors broken off, one woofer surround has a hole, missing white coating on woofers, both tweeters dead, one mid dead, one pot keeps turning, and screw post missing on rear. Cabinets have stains and chips. Now I need help on what to do with them?? Worth the time and money to restore? Part them out? I am one that hates to part things but it needs to be done, I will grab the Kleenex box.

    And I thought mine were in bad shape with their painted cabinets

    Well, all these speakers can be reconed I think but I doubt it's worth the money.

    My advice is that you put an honest ad on e-pay for the working drivers.

    "Put another L100 on the fire.
    Cook me up some bacon and some beans."

    As mentioned, there are some salvageable parts, worth more
    than your $13.

    Just an idea ............

    Your 2 woofs are working with no rubbing right ? If so the only issues are the damage to the surround and the 'cosmetic' issue with the aquaplas coating.
    Can you post a pic of the woofer surround that has the damage please , it can poss be patched up. If so then why dont you consider doing a Zilch Econowave treatment ?
    I cant recall the $$ but it is not a great amount ( $150 ? ) much less than messing with tweets and mids etc.
    Since he is in Berzerkeley you need not incur postage.
    It will need a little surgery on the cabs but nothing too difficult. After that fill the dings and re veneer or just paint them with Duraflex cabinet paint ( black )

    Do a search here for Econowave and you will get the skinny

    Good luck , Mac.

    Save the woofers, give the rest away. White out can be used as a filler for the damaged coating. You'll want to run some impedance sweeps on those poor abused woofers to make sure they're not demagged or rattling.

    Isn't that what I said?

    Frustrating to have just 1 demagged. When both are, Qts pops upward and they become useful as infinite baffle sub drivers (as long as you have a few of them, there's not a lot of Xmax).

    Yes it's frustrating, I swapped it to the center channel so I don't feel as "unbalanced"

    LOL - I thought I was the only person to do that! I use Liquid Paper (Office Depot). "White" is too white, and "buff" is too yellow. Maybe a mixture of the two?

    L88's a better starting point, but with skill and diligence, eWaved L100s can rock as never before.

    $220 per complete kit pair presently, including PC boards, waveguides, and USA shipping.

    Unimaginably, there appears to be an emerging market for well-executed EconoWaves™.

    If you don't want to do them, give me the cabs for prototyping....

    Yes, with XO boards and components; you have to assemble them yourself, though we'll do that with an upcharge....

    There yours, I am going to see if anyone wants them as project speakers before I gut em, when I gut em you can have the cabinets, I also have some jensen model 7? cabinets in the back yard if you need them for anything.

    It just looks like the money I would have to put out in order to get these going would buy me a nice working pair with good cabinets
