Analog Active X-Over Question
I have used my DCX2496 to prototype passive crossovers several times. It's a fairly straight forward process that saves a lot of time and building. Should work just as well for line level active, maybe better.

DSP works for me - but I do understand the desire to retain an all analog signal path.

Thanks Charles, this is the bit I didn't pay attention to in class. Bilinear transform - Wikipedia
As I understand it, a commercial produce should already have factored in the non linear transformation in the software and the IIR filter should have essentially the same (minimum) phase behaviour as an analog filter.
And it's mostly an academic point substantially below the Nyquist frequency, where any reasonable crossover will be.
Hence my comment that it will be "below a level that will affect you" [the OP].

Best wishes

Analog Active X-Over Question
How could we forget:

That's the obvious solution, an adjustable analog XO. Works like a charm. I am still using my old one in a secondary system. Certainly answers my biggest challenge to OPs problem which is, what do you do if you want to change the hard-wired analog XO next month?

Funny thing, newbies need to take care in using this unit because they couldn't get L and R to match by just eyeballing the tiny continuously variable knobs. But piece of cake for OP to fine-tune the knob settings with REW sweeps.

Or a simple matter to fabricate your own clone.... and skip steps 1, 3, 4, and half of 5. (Or just go DSP with a Behringer DCX2496.)

HiFi aspirations since 1957. "When the toilet paper of experience is depleted, the **** of reason goes unwiped"

Might want to check out Steve Bench's tube crossover boards.
