• The angle A shown in the illustration
should be the same.
• If you cannot place the speakers at the
optimum angle, separate the surround
speakers and the surround back speakers
adequately and arrange them as
symmetrically as possible.
• You can calibrate speaker positioning using
"Speaker Relocation" even if you cannot
place the speakers at the optimum angle
(page 103). Arrange the surround back
speakers spread further back than 90 degrees
to operate "Speaker Relocation" effectively.
• Install the front high speakers at the same
angle as that of the front speakers. The
position should be at a height on or above an
extended diagonal line across the screen of a
TV or monitor.

Tip
Since the subwoofer does not emit highly directional
signals, you can place it wherever you want.
