5.1 Systems
The IB2S-Active Series monitor has been designed for
perfect multi-channel music or movie playback. The
following diagrams indicate the ideal speaker layouts.
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.

In a system capable of 7.1 Dolby
®
Digital Surround EX ™
DTS

ES ™ or Blu-ray ™ playback, there will be two sets of
surround speakers. The first pair (surround or side channels)
should be positioned at 100º, and the second set (rear or
back channels) at 150º. (The front centre axis is 0º while
directly to the rear of the room is 180º).
