I asked Tom at Kii the effect of selecting low latency rather than 'normal'.

Hey Keith,
Has the customer heard the difference himself already? It is really not that obvious.
Low Latency Mode only disables the phase correction of the whole spectrum to minimum phase.
Everything else what´s so special about the Kii Three stays completely intact.
The whole cardioid dispersion pattern remains untouched, the frequency response and time alignement remains perfectly corrected etc etc.
Basically no analog studio monitor on the market (PMC, ATC, Geithain, you name it...) has their phase response corrected at all!
Meaning that the phase coherence of the normal mode on the Kii is something that was simply not available before in this application anywhere else.
Because of the wavelengths involved, especially if we talk 20Hz to 20kHz, a phase correction is
a) only achievable by clever DSP programming and
b) never without latency
So to recap: the Kii Three offers a preciseness in "normal mode", that is not available from any of the current studio monitors.
The transient detail and very clear depth of field at all volumes is achieved by having a completely even frequency response, perfectly time aligned drivers and perfect phase coherence.
The phase response in "low latency mode" is comparable to any other monitor this size or bigger with analog crossovers,
yet the frequency response, step response and controlled radiation pattern are still vastly superior.'
