Making active speakers with 4 Gallo A'Divas

In the process of researching new speakers for my office I've read about the benefits of active speakers over passive speakers. It came to me that I could use 4 Gallo A'Divas, controlled by an active crossover, and powered by two ROTH MC4s, to create 2-way active speakers.

A'Diva as the mid/bass and A'Diva Ti as the mid/treble. A subwoofer would take everything from 120hz down. My question is...how do I determine the best crossover point? Most speakers seem to cross the mid/treble between 1.7k and 2.2k. With full-range speakers I imagine it could be anywhere. I'm just thinking of how to make them produce the same volume/workload, so they blend well.

Any ideas?
What's a good inexpensive crossover?

Thanks!

My main thought was that its tough for a single 3" driver to produce everything from 100hz to 22khz. So if I split the signal between two of them, the load on each speaker should be much less taxing, and thus much more efficient at producing music. Simply put: going from a 1-way to a 2-way speaker, without adding the problems of a passive crossover.

I own everything except the A'Diva Ti (better treble), and the crossover. So just a fun, inexpensive project.

@Timlub: These speakers are single, full-range, and have no crossover. So I don't think (he says hesitantly) that I have to worry about the slope, etc. But I could be very wrong. :-)

@Timlub: Technically, I don't need one, as I could run two sets of them full-range, in tandem...which I will try as well. I felt that splitting the signal, and letting them each produce a part of the full signal would be easier on each one, and thus produce fuller sound.

For instance, the Gallo Reference AV uses 4 of these fullrange drivers, with a tweeter, as a single speaker. The outter 2 drivers only handle 100hz down, to free the inner 2 from having to work so hard to produce the full range.

My main question is still unanswered. I am using a sub for 100hz and below, and still need to figure out how to determine the best crossover point for the two A'Divas. I am not interested in running them full-range...thats the point of my project. To create a 2-way speaker, using an active crossover and 2 full-range single driver speakers on each side.

I need to figure out how to determine the crossover point that will provide a balanced volume from each speaker, along with not cutting into a vocal range, etc. I suppose I will just have to play with it until I figure something out.
