I did not realize that MiniDSP has recently released the ability to support up to 68 custom IIR biquads on their inexpensive balanced minidsp box, and are supposedly working on FIR support in a software update (according to a post by one their Dev Team).

Given this, it could be possible to build a custom processor either as an external box (add as many minidsp's as you want (each is 2x4) into your own box), or attached to a plate amp for powered speakers at a really low cost. As an example if applied to the coaxial wedge project, you could build a processor capable of providing 4 biamped monitor mixes for just $260 plus the cost of your blank rack mount box, connectors, psu, and cabling. Easily well under $400.
