One looking at them more closely, one of the obvious questions is whether any of them allow the roll-off slopes to be adjusted. If the high and low pass filters can be adjusted for roll-off, frequency and time delay, then they would offer a relatively cheap way to experiment with active drive (assuming you have the required channels of amplification). If however, they are fixed at the 'industry standard' of 24db/octave, then they probably won't do well in domestic design, as gentle roll-offs are more often used to integrate drivers smoothly.
