Cuboid coverage specifications

When installing loudspeakers, it’s worth taking a moment to understand how the

loudspeaker projects sound and how to get the best coverage in your venue by

careful aiming.

The coverage specs are useful for informing this important decision.

In any loudspeaker, the optimum output can be considered as the centre axis of

the high frequency driver - maximum SPL (Sound Pressure Level). The extremity

of the coverage is dened as the angle from the centre axis where the SPL drops

by 6dB to each side of the centre axis:

• 45° horizontally either side of centre for Cuboid 8, 10, 12 and 15

• 75° horizontally either side of centre for Cuboid 3 and 3TX

• 65° horizontally either side of centre for Cuboid 5 and 5TX

It therefore follows that the axis should be aimed at the furthest point of the

desired coverage area. This is also useful for controlling the amount of energy

hitting unwanted areas, such as a ceiling or wall, or ensuring SPL is not too high

for a listener near the loudspeaker (see page 14 on aiming and room coverage).

These specications refer to the loudspeaker ex-factory - with the loudspeaker in

portrait, the horn is tted to deliver coverage as shown in the table above.

If you intend to mount your Cuboid 8, 10, 12 or 15 in landscape mode (when

suspending horizontally from ceiling for instance), consider rotating the horn as

shown on the following page.

For Cuboid 3, 3TX, 5 and 5TX models the horn is not rotatable. The loudspeakers

can easily be mounted in either portrait or landscape as desired.
