Default 1st order / 3 way variable passive crossover for line level

I'm looking for a schematic for a 1st order (6db) passive (without opamps) crossover that is variable between bass/mid and mid/high frequency.

I'm building a VCA multiband compressor and want to implement 2 rotary switches for variabel crossover-points.

Examples that use the same implementation:
Tube Tech / SMC 2B Multiband Opto Compressor

Your examples are both electronic crossover/compressors.
"Outputs
The outputs are electronically balanced and can deliver >+28dBu into 600ohm (balanced).
Output impedance is 33ohm (balanced and unbalanced). "

You cannot get that sort of gain from a passive system,
