Custom Speaker Grilles – Tailor-Made for Any Audio Application

When sourcing custom metal speaker grilles, here’s the difference:

• Manufacturer / Factory – Physically produces grilles using stamping, perforating, and powder coating. Direct pricing, full quality control, no middleman. Jetray is a manufacturer – we own our stamping presses, tooling shop, and finishing line.

• Supplier – Could be a manufacturer OR a trading company. Trading companies resell from multiple factories – often higher prices, less transparency.

• Company – A generic term. Always verify if they are a factory or a trader before committing.

Why work directly with a manufacturer like Jetray?

• Direct pricing – no middleman markup

• Full control – we own tooling, production, finishing

• No MOQ – from 1 piece to 10,000+

• 20+ years – only metal speaker grilles

We manufacture custom hole patterns based on your drawing. Common options include:

Round holes – most common, good balance of strength and sound transparency

Square or hex holes – decorative designs, often used for high-end or vintage-style grilles

Slot holes – for directional sound or aesthetic purposes

You control the hole diameter (from 0.5mm to 10mm+), hole spacing (pitch), and open area ratio (typically 30% to 70%). For reference, some professional PA speakers use a 63% open area for optimal sound transmission. We do not stock “standard” patterns – every batch is made to your specification.

A properly designed perforated metal grill has minimal impact on sound. The key factor is open area ratio – the percentage of the grill surface that is open holes. Industry practice suggests that an open area of 40% or more is considered “acoustically transparent”.

However, from a manufacturing perspective, there are practical limits you should know:

Hole diameter should be at least 2x material thickness – For example, if you use 1.0mm thick steel, the minimum hole diameter is 2.0mm. Smaller holes (e.g., 1.2mm holes on 1.0mm material) will break punching pins and increase tooling wear.

Small holes cause powder coating issues – If holes are too small, powder coating will bridge over the holes during spraying, blocking them partially or completely. This affects both appearance and sound transparency. Larger holes allow powder to flow through, keeping the mesh clean and open.

Recommendation for best results – We typically suggest hole diameter ≥ 1.5mm for painted/powder coated grilles. If you need a “fine mesh” look, consider chemical etching instead of stamping – etching can produce smaller holes without the same tooling and coating limitations.

We can help you select the right hole size, material thickness, and open area ratio based on your speaker design and finish requirements. Send us your drawing – we’ll advise on what works best for both acoustics and manufacturability.

Metal speaker grill mesh is a protective cover for speakers – but there’s no single “standard” type. It can be made by:

• Stamping / Perforating – high volume, large holes (≥1.5mm)

• Chemical etching – fine mesh, small holes, complex patterns

• CNC / Laser – small batches, odd shapes, thick materials

• Wire EDM / Turret punching – special cases for precision or mid-volume

Each process has different cost, lead time, and design limitations. Send us your drawing – we’ll tell you which process fits best.
