To clarify my question, I do not care about EQ, room modes,
etc. I am interested to hear about experience with and opinions about 3-way
speakers employing digital (DSP) active cross-over (examples being Kii Three
and D&D8c) vs. 3-way speakers employing analog active cross-over (examples
being PSI Audio A23-M, ATCSCM50ASL).
If you look at those examples, PSI Audio A23-M is using propitiatory tweeter
and midrange drives developed in house, with propitiatory amplification using
unique technology such as Adaptive Output Impedance error correction feedback
system which according to them allows for superb control of excursion. They
also do phase compensation what is evident in impulse response and transients
reproduction. All of this done in analog domain, what according to them is the
proper way, not employing DSP. This certainly sounds like proper approach.
On the other hand, Kii Three does active cross-over in digital
domain employing DSP. They also do phase compensation as well as cardioid
dispersion pattern in low-mids and bass which is certainly beneficial, and
their DSP processing seems to be very well done, what is all great, but on the
other hand they use off-the-shelf drivers and amplification.
So I am interested to hear how these compare based on actual
experience and/or in lack of the actual experience opinions based on some sound
engineering knowledge (not marketing info, and not some biased pointless arguments
not founded in anything).
