Now that I live in a very small house I have to use the sound bar rather than a full blown system with my TV. Sound bars are fantastic for that is they take up so little space.
One thing that I consistently here with my sound bar is sound doesn't seem to come from them! Speech is normally centred and left and right for people on the side of the screen, but very often with the music I feel as though the sound is coming from way beyond the speakers.
So for each side I'm getting centre, left and very far left very clearly. The sounds that come from way off speaker are quite disconcerting sometimes and I do wonder how on earth does any speaker do this? It's literally as though the speaker isn't making the noise at all and there is something else going on.
This only works with speakers. The sound is manipulated and you have to hear the left and right speakers with BOTH ears for this to work. Headphones have left and right strictly separated so it doesn't work there.
You can widen the stereo image arificially (ifi has a button for it) and you can use software like Out Of Your Head but for me it doesn't work at all.
My TV can pull of the same trick when a proper TV signal is applied or it is set to 'wide'. With music the sound changes too much for my liking. Works great with movies etc.
use your EARS to enjoy MUSIC .... NOT as an analyzer
It is quite startling. I was literally looking out f the window, since some of the sounds seemed to come from extreme left, nowhere near my speaker. So clear as well. I have no sound manipulation on the soundbar either.
Sting did some experiments way back with Q sound and that was pretty weird. That sent sounds (manipulated electronically) way beyond my speakers.
You are right about hearing both speakers with each ear, since moving off axis makes the image compress back to the speakers. Also, turning your head changes it.
