Selecting the inappropriate metal speaker grill material causes many problems. You may experience sound blockage, reduced clarity, and vibrations. If your metal material is too thin, it may bend and rust the speaker grill. Over time, these issues can damage the speaker and lower its performance.
To maintain your speaker performance, you need to choose quality material. However, the selection of the right material is slightly crucial for beginner engineers. You have to consider the material properties, their durability, and reliability.
Read the guide to understand the different types of metal speaker grill material and the four manufacturers. Keep reading to explore more!
Types of Metal Speaker Grill Materials
The material used in the metal speaker grill has come in different types. Choosing the right material ensures your speaker is protected and looks professional. Below are the most common metal material types used in speaker grills.
Stainless Steel
Stainless steel is a mix of iron and chromium metal. This combination of metal alloys makes it resistant to rust. It is used to make outdoor speakers, marine setups, and car speaker grills. The stainless steel can survive in heavy rain, sun, and heat.
In terms of specifications, stainless steel has high tensile strength, excellent corrosion resistance, and a smooth finish that can be brushed. This stainless steel speaker grill material holds shape well under heavy use.
Pros:
- It is very strong and rigid
- Excellent resistance to rust
- Good under heat and stress
- Stays shiny with low upkeep
Con:
- Heavy compared to lighter metals.
Aluminum
Aluminum is a lightweight metal. However, it is strong enough to provide durability. It is used as a raw material to make home audio and portable speakers. The aluminum speaker grill material does not rust and is easy to cut or shape into custom designs.
Many car audio builders use aluminum because it adds protection without additional weight. Its specifications include high acoustic transparency and corrosion resistance. It also conducts heat that prevents the speaker from overheating.
Pros:
- It is lightweight and easy to handle
- Naturally resists corrosion
- Allows clear sound flow
- Can be anodized for style and strength
Con:
- Softer and may dent or bend easily
Cold-Rolled Steel (CRS)
Cold-rolled steel, also known as CRS, is made by rolling steel at room temperature. When the temperature reaches an optimal level, it creates smooth, strong sheets. You can use it in budget speakers or indoor systems because it is cheaper but strong.
However, it needs coating, like powder paint, to avoid rust. For specifications, CRS is a uniform surface finish, high stiffness, and smooth edges. This rust-resistant speaker grill material is easy to cut and popular in speaker grill creation.
Pros:
- It is more affordable than other metals
- Strong and stiff build
- Smooth finish for coating
- Easy to fabricate or weld
Con:
- Rusts quickly without protection
Copper and Brass
Generally, the copper and brass grills are chosen for their high-end look. Copper has a red-brown tone, and brass looks golden. These metals are softer than steel but still give good sound transparency. You can use perforated sheet metal for speaker grills in luxury audio setups, boutique speaker grills, and decorative projects.
Its specifications include natural antibacterial properties and moderate corrosion resistance. The brass is slightly stronger than copper but still easier to bend.
Pros:
- It has an attractive, decorative look
- Good sound flow
- Natural antibacterial surface
- Can be polished to shine
Con:
- Softer, scratches and bends more easily

| Aluminum | $5–$15 |
| Cold-Rolled Steel (CRS) | $4–$10 |
| Copper or Brass | $20–$40 |
How to Choose Quality Metal Speaker Grill Materials?
The choice of the right material for a speaker grill is important. The material of the speaker grill affects the speaker’s sound quality and its average life. The right choice ensures your speaker works well and looks good. Here are the main factors you should consider to select the right material.
Look for Acoustic Transparency Ratings
It is best to choose the material that has the best sound transparency rating. Metals with higher transparency let sound come through clearly without distortion. Always check the manufacturer’s ratings if available. Some materials, like steel, aluminum, and stainless steel, often have good transparency.
Prioritize Anti-Corrosion Treatments
If your speaker is installed outdoors, then it’s at high risk of rusting and corroding. So, your speaker grill material should be durable and resistant to rust. Look for speaker grills made of material that is treated with a rust-resistant coat. The stainless steel and aluminum are naturally resistant, but coatings add extra protection.
Match Durability with Use Case
Make sure to choose the material that is durable and lasts for a long time. The heavy-duty materials, like stainless steel, are best for industrial setups. Aluminum is lighter and better for portable speakers. Steel is a durable and reliable metal that protects your item. So, choose wisely to ensure your speaker grill is protected.
Budget vs. Longevity
Some metals are expensive due to their lightweight properties. Make sure to choose the metal material that won’t break your bank. Mostly, the stainless steel material is expensive because it resists rust. However, aluminum is also good because this metal protects your speaker from corrosion.

Frequently Asked Questions
How thick is the speaker grill cloth?
The speaker’s grill cloth is usually very thin. It is around 0.5 mm to 1 mm thick. It is made to be lightweight so sound can pass through without distortion. The cloth is stretched tightly over a frame to protect the speaker. Some fabrics may be a little thicker, depending on the design.
What fabric is used for speakers?
You can use polyester, cotton, or synthetic to make speakers. Polyester is the most common because it is durable and lightweight. Some high-end speakers use mesh fabrics that allow sound to pass clearly. The fabric is also treated to resist dust and wear.
Can you use speakers without a grill?
Yes, you can use speakers without a grill. The grill mainly protects the speaker from dust, dirt, and physical damage. However, the exposed cones can be damaged by pets, kids, or accidents. Using speakers without grills is fine and safe. But for long-term use, grills protect your investment.
