DSP vs. active analog crossover vs. passive analog crossover. What is your take?

agree. the question is whether it's better with an analog crossover in a particular installation. only the designer can say who has heard it both ways.

IMO it's not a question of better but which approach appeals to their potential customers. I doubt very much a designer or anyone else could tell whether an analog crossover has been replaced with digital if the digital is programmed to mimic the original analog. Of course there will be no peaking.

we will never agree on that. which is ok.😁

if i play my best 1/2" 15ips tapes (or my top vinyl pressings) all analog verses through a digital step it will jump out. OTOH the more processed recordings will be less revealing.

will every room, system, signal path be equally revealing of a digital dsp step? of course not.

This is much harder than it sounds because the high resistance and impedance of an analog crossover is not easily simulated in DSP because of the complex electromechanical interactions including with air.

DSP is far better for the crossover, equalization, time alignment, etc. but ideally like Kii does you want an amplifier designed for the application as well. 

There us often confusion between the terms active or passive,

Bi or Tri-Amping cam still use passive electronic crossovers.

I had a bi-amped setup with a passive crossover between bass anp/speaker, and then 2 level controls. Really clean and will-balanced.

Granted, the mid-hi speakers had a basic passive crossover between mids and tweets.
