I ripped of mister bench again and reworked his tone controls into a line level crossover. It adjusts from ~125 to 500hz in 12 steps and each channel has a 0 to -10dB autoformer attenuator on the output.
The plot below is how it looks when driven from a 600 ohm source set for a 250hz crossover point.
the two overlapping plots are L & R channels into a 47K load and the third trace is the left channel unloaded.

- There are no samples between 1K and 10K which accounts for the seeminly odd filter behavior. a sample at say 4K should correct the shape and make it "look" right.

- The values are not my final ones, but you get the idea.
