A CODA Audio Guide: Point Source vs. Line Array vs. Arrayable Point Source vs. Column Line Source

When choosing a professional loudspeaker system, it can be difficult to know where to start. Terms like point source, line array, arrayable point source, and column line source are common in the professional audio industry, but what do they actually mean, and which one is right for your space?

CODA Audio offers solutions across all four categories, giving system designers the flexibility to match the loudspeaker to the size, shape, acoustics, and purpose of a venue. While the technologies differ, the goal is the same: deliver clear, consistent, high-quality sound to the people who need to hear it.

Here is a straightforward look at the four speaker types and where each one can make the most sense.

What Is a Point Source Speaker?

A point source loudspeaker essentially sends sound outward from a single acoustic source. Instead of creating a long vertical array of individual speakers, a point source system uses a compact enclosure to cover a defined area.

This makes point source speakers a practical choice when you need strong output and controlled coverage without the size or complexity of a flown line array.

CODA Audio's point source range includes its HOPS (High-Output Point Source) systems, which are designed to provide high output from relatively compact enclosures. CODA says its point source products use technologies such as ring diaphragm drivers to provide high output, directivity, and fidelity.

Where are point source speakers a good fit?

Point source systems can work particularly well for:

• Small to medium-sized venues

• Front fills and delay fills

• Corporate events and presentations

• Houses of worship

• Smaller performance spaces

• Applications where a compact footprint is important

The simple takeaway: If you need a powerful speaker covering a specific area without building a larger array, point source can be an excellent solution.

What Is a Line Array?

A line array uses multiple loudspeaker cabinets arranged together to create a longer acoustic source. By carefully controlling the angle between the cabinets, system designers can shape the sound coverage to reach a large audience more evenly.

This makes line arrays particularly useful when a venue has a large audience area, significant throw distance, or challenging coverage requirements.

CODA Audio offers line array systems ranging from the compact TiRAY to larger systems such as N-RAY, CiRAY, ViRAY, and AiRAY. The company describes its line array range as covering applications from small venues through to arena and stadium-scale environments.

For example, CODA's N-RAY is an ultra-compact three-way line array designed for applications including theatres, performing arts centres, corporate events, and other small-to-medium-sized venues. It offers variable horizontal coverage and adjustable vertical curvature, allowing the system to be configured to suit different spaces.

Why use a line array?

A properly designed line array can provide:

• Long-throw coverage

• Consistent sound across large audience areas

• High output

• Controlled vertical dispersion

• Flexible coverage patterns

• Scalability for different venue sizes

Line arrays are commonly found in larger theatres, concert venues, arenas, houses of worship, outdoor events, and other spaces where sound needs to travel significant distances.

Cardioid Line Arrays

Some line array systems can also provide cardioid coverage, which helps control sound travelling behind the speaker system. This can be particularly useful when reducing unwanted sound on stage or in areas behind the loudspeakers is important.

CODA Audio incorporates cardioid technology into several of its systems, providing greater control over where sound is directed and helping improve the overall listening environment.

The simple takeaway: When you need to cover a large audience area consistently and efficiently, a line array is often the right tool. Cardioid configurations can provide additional control when reducing rearward sound is important.

What Is an Arrayable Point Source Speaker?

This is where things get interesting.

An arrayable point source combines characteristics of both point source and line array systems. You can use the speaker on its own like a conventional point source, but multiple cabinets can also be combined into an array.

CODA Audio describes its APS and N-APS products as a hybrid of point source and line array technology. They can be used individually, as fills, or combined into horizontal or vertical arrays.

The APS, for example, is designed so adjacent cabinets can work together constructively when arranged in an array. This allows the system to scale from a single loudspeaker to a larger main system without requiring a completely different speaker technology.

The N-APS takes the same basic concept into a more compact package. CODA describes it as an ultra-compact two-way system that combines the versatility of point source with the arrayability of a line array.

Why is that useful?

Imagine a venue that doesn't always require a full line array.

For a smaller event, you might use a few speakers individually. For a larger event, additional cabinets can be added and configured as an array. The same platform can potentially serve as a main system, stage fill, audience fill, or other supplementary speaker.

That flexibility can make arrayable point source systems especially attractive for venues that host a variety of events.

The simple takeaway: If you want the flexibility of a point source speaker with the ability to scale into an array, an arrayable point source system provides a versatile middle ground.

What Is a Column Line Source?

Column speakers take a different approach.

A column line source is a tall, narrow speaker that uses multiple drivers arranged vertically within a single enclosure. This creates controlled vertical dispersion while maintaining a relatively narrow physical footprint.

The result is a speaker that can provide many of the coverage advantages associated with line array technology while remaining visually and physically much smaller.

CODA Audio's CoRAY range is designed around this concept. CODA describes its column speakers as filling the gap between larger line arrays and point source systems, using line array technologies in an ultra-compact format.

One of the major advantages of column systems is their ability to help manage unwanted reflections in difficult acoustic environments. Their narrow profile can also make them an attractive option when aesthetics are important.

Where do column line sources work well?

Column systems can be particularly useful in:

• Houses of worship

• Lecture halls

• Conference and meeting spaces

• Performing arts venues

• Transportation facilities

• Reverberant rooms

• Architecturally sensitive spaces

• Applications where a discreet speaker is preferred

The simple takeaway: Column line sources are a great option when you need controlled coverage, intelligibility, and a compact, visually unobtrusive speaker.

What About Subwoofers?

While the main loudspeakers handle most of the vocals, instruments, presentations, and other mid- and high-frequency content, subwoofers provide the low-frequency foundation of a professional audio system.

Subwoofers reproduce the deep bass that conventional loudspeakers cannot produce as effectively, adding impact and depth to music, film, live performances, and other applications.

CODA Audio offers a range of high-performance subwoofers, including its SC Series, which uses Sensor Controlled technology to monitor the movement of the speaker driver. This is designed to reduce distortion and improve the accuracy and responsiveness of low-frequency reproduction.

Subwoofers can also be configured in cardioid arrangements, helping direct bass toward the audience while reducing unwanted low-frequency energy behind the system. This can be particularly valuable on stages and in venues where controlling bass spill is important.

Where are subwoofers useful?

Subwoofers can be an important part of systems used for:

• Concerts and live performances

• Theatres and performing arts centres

• Houses of worship

• Large corporate events

• Arenas and stadiums

• Entertainment venues

• Cinema and immersive applications

The simple takeaway: Subwoofers provide the depth and impact that complete a professional sound system, while technologies such as cardioid configurations can provide greater control over where that low-frequency energy goes.

So Which Speaker Type Is Right for Your Space?

There isn't one speaker technology that is best for every application. The right choice depends on several factors, including room size, audience size, throw distance, acoustics, desired output, coverage requirements, aesthetics, and how the space will be used.

Here's a simplified comparison:

Speaker Type	Best For	Key Advantage
Point Source	Small to medium spaces, fills, compact systems	High output from a compact enclosure
Line Array	Large venues and long-throw applications	Consistent, controlled coverage over large areas
Arrayable Point Source	Small to medium venues with changing requirements	Can operate individually or be combined into arrays
Column Line Source	Reverberant or architecturally sensitive spaces	Controlled coverage in a slim, discreet enclosure

Of course, real-world system design is more complicated than simply selecting one category. A professional audio system may use several technologies together. In partnership with SC Media Canada (Coda Audio’s Canadian distributor) and their team of audio experts, we are able to achieve tailored audio solutions, designing around any acoustic challenge.

For example, a large venue might use a line array as the main PA, with point source speakers providing front fill or outfill. CODA Audio has demonstrated this type of approach in real-world installations, including systems combining N-RAY main arrays with APS and HOPS loudspeakers for balcony, outfill, and frontfill coverage.

Why Speaker Design Matters

The loudspeaker itself is only one part of the equation. A great system also depends on proper placement, aiming, amplification, DSP, acoustical considerations, and system tuning.

This is particularly important with line arrays and arrayable systems. Simply putting multiple speakers together does not automatically create a properly functioning array. The cabinets need to be configured and processed correctly to achieve the intended coverage and performance.

CODA Audio's systems are designed to work with its LINUS loudspeaker management amplifiers, which provide amplification, DSP, system integration, protection, and system tuning capabilities.

That is why working with an experienced AV and audio integrator is important. The best system isn't necessarily the loudest speaker or the biggest array, it's the system that delivers the right coverage, intelligibility, and performance for the space.

The Bottom Line

Choosing between a line array, point source, arrayable point source, column line source, or subwoofer system ultimately comes down to what you're trying to accomplish.

Need high output from a compact speaker? Point source may be the answer.

Need to cover a large audience over a long distance? A line array may be the better choice.

Need a flexible system that can grow with different applications? Consider an arrayable point source.

Need excellent intelligibility and controlled coverage in a visually sensitive or acoustically challenging space? A column line source could be the ideal solution.

Need deeper, more powerful and controlled low-frequency response? A dedicated subwoofer system can provide the foundation your main loudspeakers need

CODA Audio's range is designed to give system designers options across all of these applications, from compact corporate systems to large-scale performance venues and stadiums.

If you're planning an audio upgrade, the best place to start isn't with a particular speaker, it's with the space, the audience, and how you intend to use it. From there, the right loudspeaker technology can be selected to deliver clear, consistent sound where it matters most.
