After the listening area, determine at which angle the loudspeaker array has to be
mounted. The AXIR column speaker was designed to aim the sound just above the
heads of the listeners, and it is recommended not to exceed an angle of 6°. There are
two different approaches to determine the mounting angle, each with specific
advantages and disadvantages. Which approach you choose, depends on what you want
to achieve: a maximum listening area or a minimal variation in sound pressure level.
- Approach 1: Maximum listening area
When a large listening area is desired, an angle of around 3° is recommended. When
you move away from the loudspeaker, the sound pressure level will be decreased. This
decrease depends on the reverberation of the room in which the speaker is placed.
If you want the high tones to be clearly audible, make sure the listener is able to see the
loudspeaker array.
- Approach 2: Minimal variation in sound pressure level
When a minimal variation in sound pressure level is desired, an angle of 5° is ideal for
this purpose. The size of the total listening area becomes in comparison with the
previous approach, smaller. The space nearby the loudspeaker ‘A’ does not belong to
the listening area.
(Diagram 1 shows the relationship between ‘A’ and the mounting height of the
loudspeaker when using an angle of 5°)
