The subs do work in any DSP-mode, be it direct, stereo, Trifield or any other. Equally, if I determine the center as large DSP the sub will not go silent. This is independent from having no sub for music in my settings or having a sub in the settings. So in any case I have a bass overload when having the sub switched on during music listening. The problem is somewhat smoothed out if I tell my settings that I have a sub when listening to music but put the crossover-point to 30Hz. But that is no real solution, is it? The sub's sensitivity is set to max low. Do you have any further ideas?
