What is an Array Speaker? Advantages, disadvantages, applications & top popular speaker lines

Array speakers, also known as line array speakers, have become an essential part of professional sound systems, especially in large events such as concerts, conferences, and festivals. With a unique design that allows for even and powerful sound dispersion, array speakers provide an excellent listening experience for audiences in all positions in a large space. This system not only helps improve sound quality but also optimizes installation and use in different environments.

According to Technical Document TD-1023 (2023) of the Audio Engineering Society (AES) of New York, USA: Line array loudspeaker systems can achieve stable sound pressure levels with variations of less than ±3dB over distances of up to 100 meters, making them ideal for large-scale venues and events.”

With more and more events requiring high-quality sound, choosing the right speaker system is more important than ever. However, with the variety of products on the market, consumers often have difficulty finding a reputable address to shop.

That is why Phuc Truong Audio stands out as a top choice for those looking for quality array speakers. With many years of experience and a commitment to providing genuine products and dedicated service, Phuc Truong Audio has affirmed its position in the audio industry in Vietnam.

What is an Array Speaker?

An array speaker is a sound system consisting of many individual speakers arranged in a certain structure to produce sound with wide and even coverage. This system allows users to optimize the listening experience by adjusting the sound dispersion angle. According to statistics, an array speaker system usually includes at least 4 to 6 individual speakers for the best performance.

For a performance with about 300 listeners, you need to use at least 2 pairs of array speakers, each pair containing at least 4 speakers. This helps ensure consistent sound quality for all the audience.

Structure of Array speaker

The structure of the array speaker not only helps improve sound quality but also optimizes the listening experience for the audience in large events. The combination of smart design and modern technology has made the array speaker the first choice for many professional audio applications. The main components of the Array speaker:

Speaker mount:

This is the load-bearing part, usually made of sturdy steel or aluminum, that helps fix and adjust the position of the speaker. The mount must ensure a large load-bearing capacity to keep the speaker system safe when hanging at high altitudes.

Central system:

This section usually contains the controls and amplifiers, which help adjust the volume and direction of the sound. The central system may incorporate compression technology, which allows for increased power without sacrificing sound quality.

Single speaker system:

Individual speakers are arranged in rows or columns to form a homogeneous block. Each speaker is usually of the same construction and is tuned to emit different frequency ranges (high, mid, low) to ensure the best sound quality.

Strong magnet:

Many modern array speaker systems use powerful magnets to connect the speakers together. This not only reduces the size of the system but also increases its durability.

How Array speakers work

The operating principle of array speakers is based on the interaction between individual speakers arranged in a specific geometric structure. This system allows the speakers to work synchronously to create a larger and more powerful sound wave, helping the sound to be distributed further without losing quality.

How it works:

• Speaker arrangement: The speakers in an array speaker system are usually arranged vertically or horizontally. This arrangement optimizes sound dispersion and creates a uniform sound wave front.
• Sound Spreading: When the drivers work together, they produce sound waves in a straight line shape, which minimizes sound attenuation over distance. This means that the sound will travel far while maintaining clarity and quality.
• Scanning angle: Each array speaker usually has a horizontal scanning angle of 80 to 120 degrees and a vertical scanning angle of about 20 degrees. This scanning angle is predetermined by the manufacturer and can be adjusted according to usage needs.
• Sound wave interaction: The sound waves emitted from each speaker interact with each other, forming a larger sound wave when they meet. This helps ensure that the sound is emitted evenly throughout a large space, thereby improving the listening experience for the audience in every position.

Advantages of Array speakers

Thanks to its outstanding advantages such as wide coverage, good sound quality, cost savings and convenient design, array speakers have become the first choice for many large and professional events. This system not only meets the needs of sound but also contributes to enhancing the audience's experience during performances.

Wide sound coverage:

Array speakers are capable of dispersing sound evenly in a large space, with a horizontal scanning angle of 80 to 120 degrees and a vertical scanning angle of about 20 degrees. This allows the sound to be distributed to every position in the space, ensuring that all audiences can hear clearly without any loss of quality.

Exceptional sound quality:

The sound emitted from the array speaker is loud, solid and powerful. Thanks to the arrangement of individual speakers in rows or columns, this system can reproduce sound across a wide frequency range, from 40 Hz to 20 kHz, providing realistic and vivid sound quality. The sound does not distort even at a distance, creating a great listening experience for the audience.

Cost-saving:

Using array speakers can save a lot of money for large events. Instead of investing in many separate speaker systems, an array speaker system can serve thousands of listeners in spaces such as halls or stadiums. This helps to reduce the cost of renting and installing equipment.

Compact design and easy to move:

Array speakers often have a modern and compact design, making installation more convenient. Many speaker systems are equipped with a multi-purpose hanging system, allowing users to easily adjust the position and direction of the speakers to suit their needs.

High sound sensitivity:

The array speaker system has high sensitivity, allowing it to operate effectively in a variety of environments, from large halls to outdoor spaces. This helps ensure that the sound is emitted powerfully and clearly without the need for excessive power enhancement.

Easy to adjust sound coverage angle:

Users can easily adjust the speaker's sound coverage angle according to their needs. This helps optimize the listening experience for each specific event, thereby improving the overall sound quality.

Disadvantages of Array speakers

Although array speakers offer many outstanding benefits in sound dispersion, there are also some disadvantages to note when using this system. Here are the main disadvantages of array speakers:

High price:

The investment cost for an array speaker system is often higher than that of traditional speakers. A basic array speaker set can range from 50 million to 200 million VND, depending on the number of speakers and the brand. This can be a barrier for small event organizers or those with limited budgets.

Complex installation:

Installing array speakers is often a technical task. The system must be hung high or placed on a shelf, requires the assistance of several people, and requires sound knowledge to ensure effective operation. Improper installation can result in distortion or uneven sound.

Sound quality is not good when sitting close:

The sound emitted from the array speakers can be uncomfortable for those sitting too close (less than 5 meters). When sitting close, the listener may feel the sound is harsh and does not achieve the desired quality. Therefore, it is recommended to maintain a minimum distance from the speakers to the listener to ensure the best sound experience.

Difficulty in transportation:

Line array systems are often bulky and heavy, making them more difficult to transport than other compact speakers. Moving and setting up these systems requires a lot of effort and time, especially at large events.

High maintenance costs:

Array systems can also be more expensive to maintain due to the number of speakers and auxiliary equipment involved. If one of the speakers fails, the repair cost can be high and require a specialized technician to perform.

The disadvantages of array speakers, although noteworthy, still do not reduce the value of this system in large events. Users need to consider carefully before investing in an array speaker system, ensuring that it is suitable for their needs and financial capabilities.
