What Are Speaker Covers?

Speaker covers, also known as grilles, are protective layers placed over the front of speakers. Their primary purpose is to shield the delicate components inside from dust, debris, and physical damage. But, they also play a role in the aesthetic design of the speaker, giving it a polished and finished look. Speaker covers can be made from various materials, each with its unique properties and effects on sound.

Types of Speaker Covers

Fabric Covers: Fabric covers are quite common and come in various textures and densities. They are generally used because they are easy to produce and provide a sleek, clean appearance.
Metal Grilles: Metal grilles are often found on more robust or professional speakers. They provide excellent durability and protection.
Plastic Covers: Plastic covers are typically found on budget-friendly speakers. They provide good protection and are relatively inexpensive to produce.

Fabric Speaker Covers

Benefits and Drawbacks: Fabric covers are lightweight and minimally obstructive to sound waves. However, depending on the thickness and density of the fabric, they can slightly dampen high frequencies.

Effect on High and Low Frequencies: Thinner fabrics generally allow high frequencies to pass through with minimal interference, while thicker fabrics can absorb some of these higher sounds, resulting in a slightly muted effect.

Metal Speaker Grilles:

Benefits and Drawbacks: Metal grilles are excellent for protection and durability but can cause sound reflections and diffractions, especially at higher frequencies.

Effect on Sound Clarity: The holes in metal grilles are designed to be as unobtrusive as possible, but they can still affect the sound clarity, particularly for high-pitched sounds.

Plastic Speaker Covers

Benefits and Drawbacks:

Plastic covers are durable and cost-effective. However, they can cause more significant sound distortions due to their solid nature.

Effect on Sound Quality:

Plastic can absorb and reflect sound waves, leading to a less accurate reproduction of the original sound.

Will my speakers sound better or worse with the covers on?

While speaker covers protect and add aesthetic appeal, they can interfere with sound waves. This interference, known as diffraction, happens when sound waves reflect off the covers, causing slight delays and potentially creating distortions like comb filtering. As a result, speaker grilles typically do not improve and may slightly worsen the sound quality, though the effect can vary based on the specific speaker design.

Sound Effects of Grille Diffraction

The diffraction effects of speaker grilles can impact sound, but the extent varies based on the angle and distance from the speaker. While the total output per frequency doesn’t change, the sound can be modified depending on these factors. In typical listening environments with many reflections, these diffraction effects are often subtle and not easily heard. Near-field listening is more affected than far-field due to the impact on total acoustic power.

A study using the Infinity Primus P153 showed that up to 2 kHz, the grille has little effect, but above 2.5 kHz, its impact becomes more noticeable, especially near 20 kHz, where it causes up to 5 dB changes. The effects also increase with angle away from the direct axis. Although this grille’s impact is relatively mild, it still alters the sound.

Research by Earl Geddes and Lidia Lee indicates that diffraction effects can be audible as nonlinear distortion, becoming more noticeable with higher amplitude. This suggests that while grille diffraction isn’t a major issue, it’s not entirely inconsequential.

What is the purpose of a grille on speakers?

Speaker grilles have two primary functions: aesthetics and protection. They shield delicate components from dust and curious hands (or paws) while enhancing the speakers’ visual appeal. Grilles are usually made of fabric, metal, or plastic and can often be removed, typically attached with magnets or clips.

Are speaker grilles affecting the sound quality?

Since each speaker has a unique design, it’s hard to say definitively if grilles affect sound. Grille fabric is made to be acoustically transparent, and any impact on high-frequency sound is usually negligible.

If there is an effect, it’s often due to the grille frame being too close to the drivers, causing sound waves to bounce off and interfere, especially at higher frequencies. This can alter sound patterns and cause slight changes.

However, the impact of grille frames is minor compared to placing speakers in tight spaces, which can cause more significant sound issues. So, speaker placement is more important than whether you leave the grilles on or off.

How to Design and Integrate a Speaker Grille in Three Easy Steps?

The speaker grille is often underestimated but deserves careful planning. Neglecting its impact can lead to unexpected drawbacks, yet focusing on three critical areas audio quality, durability, and aesthetics can mitigate these issues effectively.

Audio Quality:

Prioritizing audio quality is paramount. Grilles designed for multiple functions, such as vandalism protection, may compromise sound performance by adding weight and altering sound dispersion, affecting overall acoustical potential.

Durability:

Choosing the right grille material is crucial for durability. A lightweight mesh is adequate for home use, but for venues like music halls or theaters, where systems endure heavy wear, more robust designs are necessary to withstand dust and other environmental factors.

Aesthetics:

While aesthetics matter, especially in consumer products, professional audio settings often prioritize functionality over appearance. Opting for a balance that enhances performance and fits within budget constraints is key, especially when speaker systems are positioned away from direct public view.

What are the benefits of grilling as opposed to not grilling?

Speaker grilles in Dynaudio speakers primarily protect the drivers and change the appearance, but they can slightly degrade sound quality due to diffraction effects from the grille frame.

Dynaudio designs grilles to be acoustically transparent, yet acknowledges that speakers generally sound better without them. They’ve developed technologies like custom EQ curves to compensate for this when grilles are attached, ensuring minimal impact on sound quality.

Advantages of Speaker cover

Using speaker covers offers several advantages, primarily protecting your speakers from dust. Fine dust particles can enter speakers and significantly degrade sound quality over time. Additionally, dust can harm the internal drivers, potentially damaging your speakers in the long run. Investing in high-quality speaker covers helps prevent these issues.

Speaker covers also enhance the aesthetic appeal of your speakers, giving them a clean, attractive look. They can refresh the appearance of your speakers, making them stand out and appear newer. Overall, covering your speakers not only preserves their performance but also enhances their visual appeal.

Do speakers sound better when enclosed?

Sealed speakers offer a tighter and more precise bass but require more amplifier power. Their bass playback is sharp and consistent, avoiding the booming effect found in ported speakers. Additionally, they have a quicker transient response, allowing for a smoother bass decay without any lingering sounds.

Do speakers need space around them?

Placing speakers too close to side walls affects both bass and midrange output. It’s advisable to provide at least 50cm of space around most speakers to allow them to perform optimally.

Why do speakers sound better at night?

One of the main reasons music sounds better at night is due to reduced ambient noise. With fewer background sounds competing for your attention, you can focus more on the details and nuances in the music.

Additionally, lower nighttime temperatures can enhance sound quality as cooler air can transmit sound waves more efficiently. Finally, nighttime often brings a more relaxed and peaceful atmosphere, allowing for a more immersive listening experience.
