Assuming you begin with a speaker that already contains a high quality crossover, there is indeed some added expense involved.
Generally speaking, upper frequency drivers don't require as much power. If you look at the division of wattage with many multi-way speakers you can see that. Also, I find it isolates potential clipping at the bottom (which I find less objectionable) from the rest of the range where such is more obvious.
Although it's not exactly the same scenario, I high pass the small Acoustats in my HT system and supplement them with powered subs. That allows the stats to avoid diaphragm "slap" and provides more headroom. Meanwhile, the stereo subs do their thing independently for the bottom two octaves.
Another advantage is ability to use pairs of stereo amps to vertically bi-amp a speaker. That provides a similar channel separation benefit that you find using mono amps in a full range driven system. I do believe, however, that it is better to match similar amps for upper driver duties (i.e. midrange/tweeter) to maintain coherency even if their power output is different.
