But it isn't just a "cut", it is a filter. In the analog world of discrete component filters, a filter will always alter phase. Now in the digital domain is it possible to filter the frequency and compensate for time (so now it may be possible, just hard).

Filters at different frequencies (cross-over points) will result in different phase changes.

How much of a problem this is depends on how picky the listener is, and the similarity of the content between dissimilar speakers. Say the fronts are crossed at 40 Hz, and the surrounds at 80, and the low-pass portion of the filter is being routed to the same sub. If there is similar content between the front and rear the phase differential will cause a comb-filter effect in the signal which is being sent to the sub.
