The left RCA female is the input from the preamp.  The middle RCA female is the sub output and the right RCA male connector is the highpass and goes to the normal amp.

Thank you.

Yes, as you surmised, I was reading it backwards.

Built the high band pass filters per Danny’s specifications.

Input is from the right, bypass at bottom (to subwoofer) & filtered output to left & on to mono block amp for X-Static.

Way less cone movement after on the X-statics…

Do they sound better? Don’t know, haven’t listened long enough.

Capacitor:
Solen 0.10uF 700V Silver Sound MKP Silver Metallized Polypropylene Film Crossover Capacitor

$20

My amp has 25K ohm input impedance, so should filter up to about 60Hz.  Or first Octave.

  That should really help to liven up the midrange detail and dynamics as well. Keep us posted how you like it.
