RE: Phase coherence

I don't necessarily disagree with your statement. This is a tricky one for everyone to get their brains wrapped around. :)
You'll note that I labeled "phase-coherence" as more of a marketing term.
Consider the case of two identical drivers coupled effectively acoustically, but driven with two different frequency ranges (ranges within both their capabilities.) Assuming a properly implemented crossover, could/would that system exhibit "phase-coherence?"

Magnepan's are large diaphragm systems with non-coincident drivers and if we really want to get prickly and technical with the technical goal posts, I would stipulate that it's impossible to achieve phase-coherence, time-coherence, linear-phase, square-wave reproduction, etc, etc, and any other lofty objectives audiophiles might think they can achieve.

However, what Andy picked up on was a good observation.
Good fun......much more interesting than ficus tree discussions.

Regardless, I still don't think any of this is the basis for the 3.7i modification. But, just speculating on that. :)

Cheers,

Dave.
