I'm not entirely sure which speakers those are, but why wouldn't they be phase/time coherent

I think the list of phase and time coherent speakers is pretty short -- Vandersteen, Thiel and Green Mountain. There might be others, but I think these three (esp. the two former; the latter is a smaller player) really use it as an advertising vehicle.

Also, there's two camps on phase/time coherence, just like with cables. I myself have yet to see any scientific experiments that indicate phase/time coherence, within the tolerances we'd find in well made speakers, makes an audible difference.

Yeah, tough to say. I have Vandersteens, and I like the sound of them (else I wouldn't have bought them, right?). However, is that due to their phase and time coherence, driver selection, minimal cabinets, or what? I don't know, and I would say that I haven't done the research to argue either way. You're defintiely right in that there's two camps.

Plus, it looks like the tweeters are offset from the midrange and bass drivers anyway, which would imply some sort of effort towards phase/time coherence.

I think the sloped baffle is generally to address time coherence. Phase coherence must be addressed in the crossover.

Anyway, as far as I can tell it's an excellent no-compromise setup although I do think there's a fair amount of snake oil in there.

Can't argue with that.
