I'm thinking of purchasing SVS PC-16-46. My question is on my receiver, should I setup my floor standing tower speakers (PSB Stratus Golds) as small speakers? I believe this will cut all signals under 80hz to the fronts and output it to the sub? Do I want this? A sub to handle all the signals 80hz and below? Or should I have my fronts that have pretty good bass response to still handle < 80hz signals? So, set them up as large or small?
