Some of these terms can be confusing, so...
Correct me if I'm wrong, but my understanding is that a "time coincident" (origin unknown) speaker is one that basically "time/phase correct" (Vandersteen).
And, correct me if I'm wrong (again), but the typical "time/phase correct" multi-way speaker is both time-aligned and phase coherent, typically for a narrrow listening window or point in space (ear height at listening seat), and strives to keep all drivers operating in identical polarity.
Having all drivers operating in identical polarity is a big thing for some people, who claim that mixing up inverting and non-inverting drivers in a multi-way speaker inevitably prevents the reproduction of a natural or realistic sounding waveform.
Does all of the above sound correct to you?
