Generally, you would want the summed responses of all the drivers to be equal across the entire spectrum. This can change, sometimes dramatically, when listening off-axis where phase-issues between the drivers at those crossover frequencies reveal themselves. Some manufacturers are better than others addressing those concerns with better driver selection, physical design layout of the speaker, better crossover parts, and more carefully designed crossover, etc.

Also, speaker price has no necessarily guaranteed correlation on the above.
