Please pardon my limited knowledge of crossovers, but why are there no inductive coils in an L88 Plus (N88) crossover shematic?

I think we're all Bozos on this bus...
The woofer was probably ran full range, therefore, no xover components there at all.
Mid and tweet used a cap in series to set low cut off point and were ran flat out to the top of the spectrum.
I haven't seen an L88 schem in a while, so I am going on memory.

Looks like your memory is pretty good: http://manuals.harman.com/JBL/HOM/Te...0Plus%20ts.pdf

Sometimes you feel like an inductor:
L88 had one (in the highpass):

Plus don't.
Once upon a time, L100 had them, too:

What's that have to do with anything...?
Thanks for the input, gentlemen.
I am taking my L88Ps (2 pair) to the next level. I have an M12 expander kit for one (they are difficult to locate). The N120 crossover module in the M12 only adds a 10285 8 ohm L Pad and a 3 microfarad cap. I have spare 10285s. I believe I can make this modification with little trouble. 104H-2s in place of the LE5-2.
Whatta ya think?

I built charge coupled crossovers for my L100s and swapped out the LE 5-2s with 104H-2 mids. Got em hooked up to an old Mac 1900. Due to the 123A-3 woofers, they still sound like L100s, but a lot better. This is a bedroom system. I don't always sleep too good. When these are playing, this never seems to be a problem.
I think there is a better option:
