I'm under the impression: Because it's all in the marketing. There is no incentive to build a "proper high-end" fully active system for 500 Euro when you're outcompeted on price and marketing by a manufacturer offering a "pretty good but not quite high-end" 400 Euro system that sounds good enough for all but a few (and then you're all of a sudden competing with much more expensive systems as well). Also, your estimate seems off to me. I don't know your personal background, but prototyping a good-sounding speaker cabinet takes time beyond a few hours. Even more if you're aiming for mass production. Add to that the DSP + n-channel Amp board, this will be expensive, even when building 10000, AND it is not trivial circuitry to design. Also, "proper high-end" is a relative term. When researching which speakers to build and where to source chassis, I found a nearby "proper high-end" manufacturer integrating realtime measurements of cone movement into their DSP corrections... |

I haven’t looked into this space in a few years and I am of the “budget hi-fi” variety. At a glance, it does look like open source choices exist [0]. My last (finished) DIY audio project was an ODAC+O2 and that has been rock solid for 5 years.
Realtime corrections sound nice at first glance, but I’d be wary of the actual effect. It’s best handled with servo in the analog driver. DSP really shines with room and loudspeaker compensation, especially to linearize phase response (at the cost of delay). Room acoustic issues led me down a rabbit hole that ended with me working on a triple BA IEM with a teensy powered FIR crossover. I gave up on soldering wires to a tiny SM connector. It’s on my revisit list. I’ve been knocking some things out this year, so maybe it’ll be up in another year or two.
If only I could just play with toys instead of working :p
