    New crossovers for L100 - anyone try this one?

    I may be interested in trying a new crossover that's available for my 34 year old pair of JBL L88+12s (L100 equivalents) that I saw here:

    http://www.troelsgravesen.dk/JBL_L100.htm
    Described thus:
    "JBL L100 Century Up-grade Kit
    from Jantzen Audio
    The kit is suitable for those JBL variants using the 123A woofer,
    LE5-2 midrange driver and LE25 tweeter, e.g. 4311".


    This site seems to be from late 2006 to early 2007, from Jantzen Audio (Denmark). Has anyone tried this kit???
    And if so, what are your impressions & thoughts about it?
    (Hmmm, I wonder if these L88+12s could be set up for bi-amplification at the same time?).

    I have not heard an L100 with his new crossover in it. But I think it will probably work fine. I do know for certain that the redesigned crossover I posted about 2 years ago works very well. Compare that Jantzen kit's price of $298 to the price of $154 for parts if you follow my design.

    I cannot explain why the two designs are different. There are more than one way to skin a cat. I do know that I sent my design to Troels Gravesen to check out, before he came out with the commercial Jantzen kit. To his credit, he made his clearly different from mine. One possible explanation for the differences is that JBL seems to have made some LE5-2 midrange drivers over time that measured differently.
