Mike,

BBE explains their process as a correction

That explanation is pure marketing BS. If Scott says the BBE box actually
includes group delay / phase shift I'll take that at face value. But there's
no way a generic box could compensate for all the different speaker models
and crossover frequencies that are out there. It's just not possible. And
why should adding phase shift make things "clearer" anyway? Obviously the
main effect is added grunge, which might be useful to add some top end to a
dull track or mix. But why does BBE feel they have to make up nonsense about
"correcting" loudspeakers?
