By looking at the trend in loudspeaker designs it's apparent DSP has already for some time become quite mature and more easily available for DIY loudspeaker projects, and quite easy to realize quite impressive results, at least in comparison to what passive cross overs can do.
But when I read through some threads, such as the rePhase(*1) thread, it appears as if, when one wants to do a whole range of corrections for say the frequency response, phase and splitting up the crossover over say a 3 way speaker where each element is fed by its own amplifier, that the amount of taps needed for such an example would grow astronomically and hence not being feasible with something like MinDSP due to the sheer lack of processing power.
Have to point out that, I am aware my knowledge of DSP crossovers is rather thin so I am neither able to really quantify nor formulate my question very well so bear with me, yet I am imagining that realizing a high quality 3 way DSP crossover would require a whopping hundreds of thousand of taps and hence lots of processing power which rather something like a multi-core multi-threaded CPU or even a GPU for say desktop PC only can provide with.
I guess my views stems from when I look at filter response realized with only few thousands of taps, that the frequency response looks jagged with small wave ripples and quite crude "lo-fi".
So what I am trying to ask is, how many taps do we need to accomplish a high to really high quality 3 way speaker DSP crossover, including encompassing a very precise frequency and phase response correction? Is it somehow possible to calculate or estimate the amount of taps and processing power needed?
And as a follow up question, am also wondering what hardware + software options are available in order to realize a high quality 3 way speaker DSP crossover and with emphasize on DIY?

ps. please try avoid chitchatting and instead stick to the topic so we can keep the signal-noise ratio reasonable.
