Positioning & Alignment
5.1 Systems
III
IB1S-A
The monitor has been designed for perfect
multi-channel music or movie playback, and the following
diagrams indicate the ideal layout for the speakers.
• The constraints of room size and shape will often force
some loudspeakers to be placed closer or further from
the listening position than is ideal. In such situations the
time-alignment facilities of the surround processor or
monitor controller should be employed to compensate.
• The subwoofer carries the LFE signal as well as the low
bass from some, or all, of the main monitors when bass
management is being used. The subwoofer should be
placed at the front of the room, the optimal position
providing the smoothest low bass without boomy or
weak notes.
