I wasn't really sure where to post it but my situation is that I need an
inexpensive (hobbyist) DSP solution to turn a single input into a 5-way
crossover (distributing the signal across a sub, 2 mids, and 2 tweets) output.
I've considered doing an active crossover out of pure components, but a DSP
solution can give me flexibility (such as adjustable crossover) that would be
ideal.
So far I have only found stuff like miniDSP which is both expensive and only has
4 outputs. Any help in this would be great.
Board for a 5 way Crossover

Why do you call it a 5-way x-over? From your description, it appears
you're speaking of a 3-way x-over, as follows:
- Sub
- Lo (2 drivers in parallel)
- Tweeter (2 drivers in parallel)
A true 5-way x-over has the following output bands and separate amplifiers for each:
- Sub
- Lo
- Lo-Mid
- Hi-Mid
- Hi
Note that the transducers (drivers) are different for each of those 5 bands.

I don't think they come much cheaper than miniDSP. Have you seen the
2x8?

You could also look at Soundeasy, which has a crossover emulator. The
approach would be to measure your drivers, combine them into a system
design based on an analogue active crossover, and tweak away until you like
what you hear.

Is this all for just a single channel studio monitor/speaker? How much
hardware experience do you have? I don't know of any cheap development
boards that could be used for this, as virtually every cheap dev board only
comes with 2 channels of audio output. If you're not opposed to 'rolling
your own' hardware then there is an infinite number of solutions available.
