Viscount
Wayne,
I totally buy the idea. I always wandered what can be done about the ugly notches right above subwoofer crossover point. With my faulty implementation of the flanking subs technique, I've seen the proof of how well additional sources in the region can deal with the problem. I am still planning to try a passive helper woofer or small sealed active sub with pro woofer approach you suggested a few post earlier.
But I am not sure properly set up (blended, one per channel) flanking subs can act as front stage subs for multisub in home theater environment. I would probably still use at least one powerful subwoofer upfront reproducing summed LF signal.
