What angling a line array really means

Angling a line array involves working with two different but complementary parameters:

• Global tilt of the entire array

• Inter-cabinet angle (splay), which defines the curvature of the array

The combination of these two factors determines which part of the audience each module covers. A properly angled system distributes the workload: lower cabinets cover near-field areas, while upper cabinets provide long-throw coverage, ensuring consistent sound pressure throughout the audience area.

Why angling is critical in line array systems

Sound level decreases with distance. As a result, near-field listeners require much less energy than those farther away. If all cabinets are aimed in the same direction:

• Front rows receive excessive sound pressure

• Rear areas lack level and clarity

Correct angling compensates for this naturally, without overdriving the system or relying on extreme equalization.

How to approach line array angling in a simple way

A clear and effective way to design a line array is to divide the audience into zones:

• Near zone

• Mid zone

• Far zone

Each zone must be covered by one or more modules, each aimed appropriately. In practice:

• More splay at the bottom → better near-field coverage

• Less splay at the top → greater throw and reach

This results in the characteristic progressive curvature seen in modern line array systems.

Line array angling in indoor venues

Indoors, the main challenge is not distance but acoustic reflections from ceilings and walls.

The primary goals are:

• Maximizing speech intelligibility

• Preventing sound from hitting reflective surfaces

• Maintaining tight control of energy outside the audience area

Typical strategies include:

• Increased curvature in the lower modules

• Precise control of the global tilt

• Avoiding aiming the top cabinets above the last audience row

Models such as CLA21 and CLA21 PLUS offer an excellent balance between coverage and control, making them well suited for theatres, auditoriums, and multipurpose halls.

Line array angling for outdoor applications

Outdoors, reflections disappear, but other factors come into play:

• High-frequency loss over distance

• The need for long throw

• Large and widely spread audiences

Here, the priority is to preserve energy toward the far field without opening the array excessively. Common practice includes:

• Minimal curvature in the upper section of the array

• Progressive curvature toward the bottom

• Level and EQ adjustments by coverage zones

Systems such as CLA312, with tighter vertical control per module, are particularly effective for long-throw applications and large outdoor stages.

The importance of the line array model when angling

Each line array model influences the system design:

• CLA208
  Compact format with wide horizontal coverage, ideal when audience width is the main requirement.

• CLA21 and CLA21 PLUS
  Highly versatile systems that allow balanced configurations for both indoor and outdoor use.

• CLA312
  Designed for demanding applications where control and long-distance projection are critical.

Choosing the right model significantly simplifies the angling process and improves overall results.

Angling and tuning: a combined approach

Angling defines where the sound goes, but fine-tuning completes the system:

• Level reduction on modules covering near-field areas

• Progressive EQ adjustments along the array

• High-frequency compensation for distance in outdoor setups

The goal is not to mute cabinets, but to distribute sound energy in a coherent and controlled way.

Common mistakes when angling line arrays

• Using the same angle for all cabinets

• Aiming above the audience area

• Forcing the main array to cover front rows without additional support

• Applying the same design criteria indoors and outdoors

• Designing without a clear coverage strategy

Avoiding these mistakes dramatically improves system performance.

Conclusion: angling as a control tool

A correctly angled line array delivers more consistent sound, higher efficiency, and a better listening experience. Tecnare line array systems—such as CLA208, CLA21, CLA21 PLUS, and CLA312—are designed to facilitate this level of control and adaptability across a wide range of applications.

In professional sound reinforcement, angling is not a detail: it is the key to making the system work as a whole.
