EQ is pretty straightforward. The main network is the 4uF//4.7
ohms. Normally, this kind of network is used in a Constant
Directivity Horn to equalize it for a flat response. But
instead of "Flat", my eq results in a treble boost.
8.2uF is a sweetener. This capacitor attenuates the 2,250Hz
hump, resulting in a much more natural sibilance.
with Full Passive Crossover
woofer network looks complicating but if you break it down
in stages, it's quite simple.
network with the 0.95mH is a shelving filter. Its purpose
is to flatten the 1kHz~2 kHz region, thereby eliminating
the "Glare" in the mid-range. Without this network,
"listening fatigue" will set in.
next network with the 1.5mH is a Bass Boost shelving filter.
Lastly, the 10uF+10 ohms is for impedance eq.
