Crossover Software: How to Crossover at Source

[rushbikes]

Is anyone managing their crossover points at the source? I.e., using PC/Mac software to split the digital output signal from their computer (before it leaves the computer) into multiple digital outputs with different frequency bands (2 or more USB outputs) that run to independent external DACs and amplifiers before reaching drivers?

Forgive me if this is already commonly done or outright nonsensical. Relatively new to the DIY speaker space.

With a 4 or more channel audio interface you can use Jriver or similar to implement a XO, EQ, FIR etc.

Example of a USB 4ch audio interface would be Focusrite 2i4.

MiniDSP has stuff too but probably requires SPDIF from PC to the DSP board.
