I agree with the advantages mentioned and think it's worth emphasizing Erik's comment "Reduced effects of microphonic interactions with the speaker". That translates to blacker background and lower distortions.
It's a shame that perceived visual issues have resulted in fewer external crossovers, especially since most of them sit right behind the speaker which is pulled out from the wall anyway. Usually they can't be seen from the listening area and even if they are it's less visually imposing than making the cabinet twice as deep for the extra room some require to include the electronics.
The cost of another pair of extra chassis especially with upscale veneers adds significantly to to production cost. So do multiple strands of high quality jumpers like the silver ones that Nola uses. Cheers,
Spencer
