Interesting. I never thought of it this way because I am dealing with multichannel HT so bass management is a given. If I used subs for the individual channels only, they would never get the LFE or LF content from other channels. Seems a little wasteful to me. Besides I would not know how to implement it even if I wanted to try. I guess if the receiver has line level outputs this could work. Still I'd probably want at least one powerful sub upfront that would be getting summed LF signal.
The (apparently wrong) way I had it done in my system was by setting the LPF on the receiver high, say 120-150Hz, setting the mains to "full", and adjusting LPF on the distant subs only to values under 80Hz. This indeed helped with the interference notches all the way to 200Hz or so.
How powerful would the flanking subs have to be in your scenario? Can they be limited to, say, 60-250Hz range?
