    L88 Plus upgrade??

    Hi. New kid on the blok and am assembling a pair of L88s from the component parts. Have everything but the tweets, being delivered. Am wondering if the mod with the midrange and crossover are available anywhere?

    I would guess that adding a mid makes it almost an early L100 and that said L100 (the one with the LE20) network would suffice

    The actual upgrade kit may be hard to locate..

    Hello

    If you have L88 Plus you should have a precut hole in the baffle for the M-12 Expander kit. 88 + 12 = L100. You should also have Le-25 tweeters.

    All you need to do is use the Late L100 schematic or the one above for the capacitor values and drop in an LE5-2 into each cabinet. The one posted in the previous post is incorrect for Le-25 version of the L100
