Trevor, I think you think that the front subs in an active LFR set-up are fed high level from the speakers. They are not. Each DSP box has a sub out low level with 0, 40, 60, 80, 150 Hz cut-offs. 0 means the actives play full range. You can of course control the sub's range via it's own cut-off rotary switch. The lows are absolutely awesome.

One thing that is missing is a relative "sub to LFR distance" adjustment. The sub therefore can't be placed further from the MLP than the LFRs.
