Hi all,
DSP seems to have endless possibilities. What I am looking for is - a high end quality - DSP which can be freely programmed as a 2 X 3 (or 4) way crossover,
which then can correcting all individual speaker units, eg woofer in closed compartment, phase correct (ing) for phase shifts and room correcting.
Does this exist? PCB's or complete devices? Most if not all searches return MINI-DSP, why "mini"? Then some have digital inputs only, I think I need analog input.
Oh why isn't here a DSP thread other then the MINI-DSP?

I assume you want a hardware-DSP processor to be used a both a crossover and for room correction. You might look for a DSP processor that includes DIRAC room correction. For example:
miniDSP FlexHTx with multichannel DIRAC option:
https://www.minidsp.com/products/ht-series/flex-htx
This has eight analog input (balanced and single-ended) and eight analog outputs. You can use it for up to a stereo 4-way loudspeaker.
This costs about US $1250 when configured with DIRAC.

High quality USB sound cards are available at reasonable cost second hand, like Motu, Focusrite, Behringer etc.
You can then do the processing in a PC, Raspberry Pi etc. - doesn't need to be too high spec - I'm using a cheap mini PC, but might switch to a Raspberry Pi 4 later
Reaper is a good software tool for this, or you can look up Camilla DSP on here

How does MiniDSP FlexHTx noise/sound quality compared to some of the higher dollar DSP models, e.g. Danville dspNexus, DEQX Gen 4, etc?
I have no idea, no personal experience comparing these products, but since miniDSP finally used much better quality DACs in this product and so I expect it to be very transparent.
I found that tbe Mini DSP has a higher noise flor than pro units; I can hear an audible hiss in my horns either it.
