First understand that bass rarely will load in a room in the same plain as the mids and highs. Also controling bass resonance in the same cabinet as mids/highs is expensive.
Deep or powerful bass requires a lot more power than mids/highs, requiring a separate amp.
Most internal XOs are a compromise based on the designers room, equipment and listening bias.
When you want to get at hi-end magic get a pair of Magnepan 3.5R or better, or Emerald Physics CS2s where you biamp (and maybe still incorporate a powered sub) cutting off the frequencies via the active XO. This allows you to adjust for room, components, listening bias, etc.
