Dear Pryso: I want to add ( a little late!. ) that even if the main speakers cross-over is at 160hz like you say and other benefits that the ones I posted earlier one advantage using separate self powered subs is that that separate subs can more easy be integrated on the room due that you can move it anywhere you need where in a full range speaker you can't because the woofer driver is an integrated part of the speaker and when you move the " whole " speaker to " tame " the bass response you " alter " too the full frequency speaker response .
In other side when you have separate self powered subs ( in true stereo fashion conection. ) using an external electronic crossover always your main amplifier will be liberate it for the low/deep bass response/handling and this means thet that main amplifier will perform better than full range, everything in benefit of an improvement in overall quality audio system performance.
Pryso from my experiences IMHO it is very very hard to beat a satelite/subs main system ( I support/recomended this kind of approach. ) against a non powered/passive non-separate full range speaker and even a self powered non-separate system.
Regards and enjoy the music,
