Pass Labs B4 crossover questions

I assume that is simply a matter of changing to appropriate filter Rs & Cs. As i understand it, 1st order to 4th order and the nature of the rolloffs controlled by the passive parts. This should be a very versatile device.

I must send you one.

The crossover has a high-pass and low pass jumper selectable for 6, 12,
18 and 24 dB/octave. The frequency of each pole is independently
adjustable with on-board pots for 2 octaves - 1 octave on each side of a
center value set by the capacitor. In "ordinary" use, all caps are the
same values. The board accommodates pcb-mount connectors and level
pots, or wires can be run to external components.

This sounds great!
