Speaker placement

To recreate a diffused surround sound field, the rear and side speakers should be installed 30 to 60cm above ear level. This arrangement works best for movie soundtracks, though you may drop the height difference in the case of multichannel music such as Super Audio CD and DVD-Audio--these materials are encoded in the studio with directional surround effects in mind.
Take some time to experiment for the ideal subwoofer placement, bearing in mind the bass reinforcement benefit from a corner installation. Having said that, do ensure there is ample space clearance for the speakers' ports and to avoid tight quarters. The latter usually results in boomy and bloated bass, instead of a nimble, tight and deep delivery.
