I already have computer and sound card, was looking at saving myself buying an extra piece of hardware for now, but allowing some projects to go forward without having to buy more stuff at the moment.
The easiest, IMO, is to do it half-assed, in which case, you don't even need a sound card.

1) make a really minimalist passive crossover: a single cap, or whatever you need to protect the HF driver(s) + one coil for the woofer.

2) measure.

3) use Equalizer APO to edit the signal, so that the output is ~flat.

This worked well when I tried it in a small speaker. Before applying EQ, the raw response was fairly well behaved, but the tweeter was far more sensitive than the woofer.

Probably not good if you have hard to tame drivers, and probably a bit annoying if you constantly switch between outputs (e.g. headphones and speakers) when using the PC.
This edit signature thingy is seriously hard to find
