And those multichannel dacs get quite expensive on their own. While the DEQX seems expensive (there are costlier alternatives out there), I don't think it's too bad for all it offers in the package.
I've heard of some people hacking a Behringer DCX2496 with a better power supply and tapping the digital outputs directly instead of using the internal dac. Then all you'd need is a filter for phase, assuming that the drivers are at least in matching phase at the chosen crossover points. That's probably the cheapest option but requires some DIY skill.
Here are some good resources for your reading pleasure :)
The first link has some great visual illustrations of the effects of crossovers.
How about a acuphase 20 k and nonsupport
And to me support is paramount.
I went through hell setting mine up
And this is far more complex.
The built in room EQ alone is more than I want to deal with
If you think about is all the bull we go through
With dAcs and amps CPU configuration a to what end
If the speakers are effected by the room how can we get it done correctly
Pros do this all day not us.
Yes it is very complex, you can make it sound worse than a passive crossover quite easily. Order of magnitude more complexity for a moderate gain in sonic performance. Active will always beat passive when setup properly though, and that has been proven. Keep at it Al!
