I am looking for a GOOD SUBWOOFER to intergarate into my home theatre/ music system, I have an arcam avr 100, but it does not have the option of playing the subwoofer in two channel mode, I need the sub to be able to hook up in in two channel mode an in lfe mode, or is it possible to just hook the sub up from the speaker line level inputs and just play it with movies and music tht way, but will I be missing out on something when I play movies?
