Can't answer your question but if I remember right you can't use SAM and the Devialet built in crossover settings at the same time so any subwoofer that you connect will get a full range signal as will your main loudspeakers. You could of course use an external crossover/DSP/filter for your sub but you can't high pass filter your mains LS without disabling SAM.
