an active crossover to two amps is in my opinion the best all around way to go.
does Dubroach Production pay royalties to the artists for the tracks played?
If you already have the bass bins, and are happy with them, changing them for actives just to remove a few metres of wire doesn't feel worthwhile.
And with the price (and weight) of decent quality power amps now, a decent passive low frequency crossover for a thousand watts isn't going to come in much cheaper – or all that much lighter.
And the active system gives you that much more flexibility to adjust things, match sensitivities and even phase, as well as the extra channels of amplification giving you a "show must go on" capability, if things go pear shaped. If you need EQ you can put one in the amp rack; programmable, direct access, anything you can get built into an amp you can also buy in a separate rack unit. And a number of crossovers offer limiting on individual frequency bands, so the fully processor controlled system (which might have been best if you were buying everything at once as a matched system, but even then I'm not certain) doesn't gain in that point of view (and if it goes wrong, who's going to fix it?
