Ah this is the thing I'm trying to say Ken you've turned your sound bar into a surround sound system by putting the speaker behind you now I can understand where your coming from you've set up like my sound system\ said:Our sub woofer is behind the couch, and I can assure you we hear knives and bullets whizzing past our ears too. I once was l ike you and thought sound bars were rubbish (the early ones maybe were) but this is definitely not crap, I don't know the technical jargon but apparently the six speakers in the sound bar are all angled so that sound bounces off the walls and the sub woofer fills any gaps.
So we agree your getting the same sort of sound that I do so no wonder you think it's good because it's the same as mine only I have the extra speakers positioned around the room
