I'm sure x3workshop will provide a more informed reply. To me, this is just common sense. We all know floorstanding loudspeaker design is a tradeoff / compromise across such a wide frequency range. Nothing depicts the lowest 100 Hz better than a good, purposely-designed SUB.
Now, instead of reinforcing those low frequencies with the SUB, the filters allow a seamless, continuous bass line across both camps (under and above 100 Hz). The added benefit with the approach is the relief on the flea-powered amp of those nasty last 100 Hz. The end result is better bass, mid-range and highs.
To answer your specific question, you can either use a lower std high-pass filter at 50Hz or you can use the std 100 Hz filter and lose representation of frequencies: 91, ... ,100Hz. Both approaches are improvements, as those last 50 of the 100 Hz range are the most difficult. Your choice. I would personally sacrifice those 10 upper Hz and improve the rest. Maybe this supplier can accommodate a custom 90 Hz High Filter?
