George Augspurger's classical dual-chamber reflex of the late 1950's had 2:1 chamber volumes, 3 indentical vents, one innner connecting vent and two external vents. It could be used with any reflex "alignment" giving ~the same LF and a mild dip - I should have the late Bob Bullock's program somewhere - it had a few bugs requiring some double checking so values between the sytems werne't shared - its in DOS so XP can't freeze the screen.

you would select the vents all equal and with two to tune the whole volume. the inner vent drops out at low frequencies.

I can't figure yours out.
