Hi

My setup has 5 active analog speaker with a range of 35-20k Hz. The sub can do 18-100Hz. Currently I set the bass management to: all large and LFE sub with low pass filter at 30Hz (I don't want the sub to try to do anything above 35Hz).

But after reading this ... I asked myself, why not try setting: all small and mono sub with 35Hz crossover. But the question is.. does the 861 then only route the 5 channels to the sub or all 6? Do the sound mixers put all the low frequency info on all 6 channels (same amount and level)?

When setting all speakers to small, does the crossover limit the sub too? If yes, why isn't the LFE low pass filter disabled?

And what does the toggle 'all subs are thx or flat to 20hz' do? Does it maybe rolloff below xxHz to protect the sub??
