• Hallway/Room
Wall baffle speakers work well with rooms and
hallways that are 20' to 60' wide. Layout starts at
one end of the hallway or room. The first speaker
should be installed 10' from the end of the hallway
or room. The next speaker on that wall should be in-
stalled 20' from the first speaker, as should any
additional speakers required to cover the length
of the hallway or room.
The first speaker on the opposing wall should be
installed 20' from the end of the hallway or room,
thereby staggering the speakers. Each additional
speaker should also be installed 20' apart from
the previous one. (See Figure 1.)
• Open Area
The number of speakers needed to cover an open
area and the layout of those speakers is contingent
upon the availability of suitable mounting points in
the area to be covered.
Layout starts in one corner of the room. The first
speaker should be installed 10' from the corner of
the room with each additional speaker in the first
row installed in increments of 20' from the first.
Based on Figure 2, install the next row of speakers
30' from the first row and 20' from the wall with
increments of 20' between each speaker. The third
row would follow the example of the first and each
additional row would continue this pattern of
alternating rows until the whole area is covered.
Wall Baffle Speakers
The layout of the speakers should be planned prior to
installation. Because wall baffle speakers are designed
to project forward, it is best to aim them in the same
direction, as this provides for both greater coverage and
clarity. You can use the building’s roof pillars or other
available supports for mounting the wall baffles. In
some cases, it may be necessary to mount the wall
baffles on opposing walls. In these cases, the speakers
will project sound in opposing directions.
