I just setup 2x Dali Motif LCR speakers with a Sonos Amp. The Dali speakers are nice and precise, but they have almost no low-frequency capability. I dug up an old Jamo passive subwoofer that has stereo input with normal speaker connectors (eg it has 4 connector). It is designed to pass the sound to two satellite speakers ( i guess it has some frequency filter internally), so it also has 4 output speaker terminals.
Obviously I cannot connect it as a normal active sub, but I can connect it as a normal stereo speaker set.
So basically I have 4 speaker cables, and I am wondering if its best to connect all 4 to the speaker terminals on the Amp, or if I should connect only the subwoofer, and then connect the Dali speakers to the subwoofer.
