Example 1: Horizontally distributed AQ5 loudspeakers are required to cover smoothly

from a minimum listener distance of 3m. The spacing required is 1.73 x 3m = 5.19m

for very smooth coverage.

Example 2: Horizontally distributed AQ12 loudspeakers are required to cover smoothly

from a minimum listener distance of 6m. The spacing required is 0.84 x 6m = 5.04m

for very smooth coverage.

The above calculations will provide very smooth coverage with approximately 3dB mid-

band sound pressure level summation. Wider spacing (up to 2 x the above figures) may

be acceptable where budgets are tight… but with slight tonal inconsistencies and less

useable summation.

10. AQ Series arrays

AQ Series loudspeakers may be arrayed to increase coverage or sound pressure level.

When arraying AQ8, AQ10 or AQ12 loudspeakers from ceiling brackets, allow approximately

100mm behind each loudspeaker for loudspeaker bracket clearance.

Recommended maximum and minimum AQ Series loudspeaker centre-to-centre splay angles are

shown in the following table. Maximum splay angles will provide maximum coverage. Minimum

splay angles provide an element of summation – typically 3dB between loudspeaker centres.
