my suround backs are 2.5 metres apart screwed to my dvd storage cabinet. The 3 seater settee sits almost immediately in front of the cabinet. Do I point the surround backs forward towards the main two speakers or inwards towards the settee which is less than 2.0 metres wide. Also does it matter too much if the speakers are raised and point downwards a little? Ultimately I may have no option so its a moot point, but worth asking.
