I remember being at a B&W dealer and listening to the N803, and after a couple of minutes I'm getting into the groove and liking the sound well enough. I look over and see this big B&W subwoofer sitting on the side. I ask the dealer if the sub is on? "No." I listen some more, it doesn't sound right. I go over and put my hand on the sub, it is on after all. "Woops!" The dealer sets it up right, and then it is clear why he was trying to sneak the sub in. Flat lifeless bass - not musical at all.
