Adjusting attenuation of Hiraga x-over passive equalization section

Hi!
From the soundpractices article, the Hiraga xover attenuates 1k-5k about 12 db.
288G is rated about 109 db spl/1w/1m, while 288 16K is 115 db. a difference of 6 dB.
I was thinking to play around with the attenuation of the Hiraga x-over equalization section that had a 6.6 mH parallel 24 ohm parallel 0.82 uF and the entire section in series with the driver.
1. I interpret this equalization circuit as follows:
a.) 0.82 uf allows the high frequencies above ?? 12.5 kHz ?? to bypass attenuation
b.) 6.6 mH allows the lows below ?? 500Hz ?? to bypass attenuation.

To play with the attenuation, i will have to change the 24 ohm resistor. But if I do so the impedance presented to the crossover in the preceding section (10uf series, 6.6mH parallel with driver), will change and therefore the xover point will shift?
Can anybody help?
Does this mean Ill have to learn Spice?
