McIntosh MC901's internal active crossover & speaker's internal passive crossover

hi all,
There are two sets of crossovers in a single system. What do you think? good or bad? why or why not?

To maximize the performance of MC901, do I need to disconnect speakers' internal passive crossover from the bass, mid range and tweeter units?

thank you!

TIA

In case 3, higher possibility of ground loop noise. Also should avoid many Class D amp as well. However, case #3 is rare!
