Use the following table to help calculate the ideal starting distance from adjacent walls and the distance between
each adjacent loudspeaker. Multiplier A is for vertical and horizontal spacing. In order to cover a large area, wider
variances in coverage may be acceptable. For our example, a direct field variance of 6.0dB is desired. That corre-
sponds to a multiplier of 3.0.

Multipliers for FreeSpace
6 loudspeaker spacings are shown up to 6dB direct field coverage. This spacing yields no
more than 3dB of reverberant field coverage, the industry standard.
Direct Field Variance
Multiplier A
Calculate the loudspeaker placement for this installation.
For placement of loudspeakers from a wall, multiply
For placement of loudspeakers from each other, multiply A x H. In our example, 3 x 6 feet = 18 feet.
So in our example, the loudspeakers will be placed at the 9 foot mark from each wall. This gives an 18 foot distance
between each loudspeaker. Be aware that not all installations will lend themselves easily to the formulas but the
formulas can be a great aid in determining loudspeaker placement. Your experience and judgement will be an
invaluable asset in determining loudspeaker placement.
Note: The loudspeaker layout should be centered in the room so the distance between the loudspeakers at the edge
of the layout and the perimeter walls is fairly uniform. If necessary, shift the entire loudspeaker layout to ensure a
consistent border. DO NOT install loudspeakers less than 3
tion in bass due to the proximity of the wall.
