Flawed? Wilson's Aspherical Propagation Delay

Greetings,

I've always wondered about this...

Recently I read an interview with Alon Wolf who stated that separating drivers into boxes that are adjustable would not work for him because the crossover would need to be reworked or adjusted.

Wilson is proud of their adjustable cabinets in their upper models, but I'm wondering how, in technical terms, they avoid phase and time errors and as Alon pointed out, how the crossover deals with the drivers in different locations and different angles?

I've heard Wilsons set up before and there is a distinct advantage to the adjustable enclosures when they are setup optimally for the listener's height and distance from the loudspeakers, but is there a shortcoming or compromise in doing so?

The German Ascendo speakers have a movable tweeter by which
you need to first measure the distance between your ears
and the tweeter and then use an instruction diagram to determine the right distance of the tweeter. The designer
Prof. Scheuring developed a special crossover for the band
pass woofer & mid/bass driver such that both are in phase
as well as time aligned. Jonathan Valin wrote about the
version M-S Mk II (the most expensive one) in TAS ,November
2006.BTW he was very impressed.
