Other than visually the width of the soundbar vs. TV makes no difference. The soundbar usually goes just below or above the TV. Since it is on a table you could mount it on the wall above or raise the TV enough for it to go underneath. Sometimes you can just put it on the table in front of the TV but this usually blocks the IR from your TV remote. The sub should go somewhere closer to the TV than where you sit if possible. This gets you a better blend and the bass level is more consistent for multiple seating locations. If you want louder bass put it closer to a corner. If you want tighter bass away from the corner.
