But also what I was getting at with mentioning the common room correction systems is these days, you can do something like take a textbook Linkwitz Riley 4th order crossover, do the little bit that's necessary to match levels, and then just call it good and let the receiver's DSP handle the large scale FR response. That advice might annoy some more knowledgable people, but the blunt truth is it'll work and done with reasonable care you'll have a truly impressive system for the price.

I don't know pro gear that much but my understanding is there's a bunch of vendors now that package DSP + ClassD amps in a way the speaker companies can white label as their own. Kinda like half the AV receivers on the market are ultimately mildly tweaked Audyssey designs.
