Frequently Asked Questions

Everything you need to know about our tweeter diaphragms, OEM capabilities, compatibility, and ordering process.

ℹ️
Important Trademark & Compatibility Disclaimer: All manufacturer names, brand models, or part numbers referenced on this site are used strictly for identification and compatibility confirmation purposes only. Our products are premium-quality compatible replacement parts engineered to meet or exceed original specifications, and are not manufactured by or affiliated with the original equipment manufacturers (OEM).

Product & Technical Specifications

A tweeter diaphragm is the vibrating component inside a compression driver or high-frequency tweeter. It converts electrical signals from your amplifier into high-frequency sound waves and plays a decisive role in the acoustic clarity and power output of the driver.

We manufacture diaphragms using a wide variety of materials tailored to different acoustic requirements, including:

  • Titanium: Excellent rigidity for high-power PA systems.
  • Phenolic: Warm sound and extreme durability in harsh environments.
  • PEI & Kapton: High-temperature polyimide films for extended heat resistance.
  • Silk / Fabric: Exceptionally smooth, natural high-frequency response.

We manufacture a complete range of standard voice coil diameters, including 25.4mm (1"), 34.4mm (1.35"), 35.5mm, 36mm, 44.4mm (1.75"), 51mm (2"), 72.2mm, 74.5mm, 75mm (3"), 99.2mm (4"), 120mm, and more.

Standard impedance options are 4Ω, 8Ω, and 16Ω. Custom DC resistance (DCR) and impedance matching are available upon request for custom or OEM/ODM projects.

Yes. We support custom tooling, stamping, and voice coil winding based on your technical drawings, samples, or specific dome geometry specifications.

Acoustic Performance & Application

Titanium diaphragms are the industry standard for professional PA (Public Address) systems and concert line arrays due to their superior structural stiffness, high heat tolerance, and capability to handle high Sound Pressure Levels (SPL).

Silk and Phenolic diaphragms are generally preferred when a warmer, softer, and more natural high-frequency response is desired. They excel in studio monitors, indoor audio, and vocal-heavy sound reinforcement.

Power handling depends directly on the voice coil diameter, former material (e.g., Kapton vs. Aluminum), wire type (CCAW or Pure Aluminum), and cooling design. Please share your driver model with our engineers for exact RMS/Peak wattage ratings.

Yes. We utilize high-temperature Kapton/Nomex formers, heat-resistant adhesives, and pure Titanium domes engineered to endure continuous high-temperature operating conditions without voice coil deformation.

Selection depends on: 1) Compression driver model, 2) Inner voice coil diameter, 3) Impedance (Ω), and 4) Desired acoustic tone. If you are unsure, send us pictures or dimensions and our technical team will recommend the exact match.

Compatibility & Replacement

Yes, we design and produce high-performance compatible replacement diaphragms designed to fit many popular pro-audio compression drivers in the global market. Note: Our products are aftermarket replacements engineered for precision fitment and are not original OEM components.

Absolutely. You can ship a physical sample or send detailed 2D/3D CAD drawings to our engineering facility in Guangzhou. We will measure the dimensions, DCR, and dome height to manufacture an exact compatible diaphragm.

To ensure 100% accurate fitment, please provide our sales team with one or more of the following details:

  • Original compression driver model number
  • Inner voice coil diameter (e.g., 44.4mm or 74.5mm)
  • Terminal placement & distance between mounting holes
  • Clear photos of both the front and back of your old diaphragm

OEM / ODM Customization Services

Yes! As a specialized acoustic component manufacturer, we support complete OEM/ODM production for international audio brands, wholesalers, and assembly factories worldwide.

Yes. Custom logo silk-screening, laser marking on terminal rings, or custom polarity stamping (+/-) can be applied according to your design specifications.

We provide full packaging customization, including custom individual plastic boxes, branded inner cartons, barcode labels, and master shipping cartons designed for safe long-distance transport.

Yes. Our in-house engineering team uses precise tooling equipment to develop new diaphragm moulds, terminal plates, and voice coil assemblies directly from technical drawings or physical samples.

MOQ varies depending on whether the item is a standard replacement model or a fully customized tooling project. For standard models, flexible small-batch quantities are supported. Please contact us for specific MOQ details.

Quality Assurance & Testing

We execute strict quality control across 4 stages: 1) Incoming raw material inspection (titanium foil, copper wire, glue), 2) In-line assembly monitoring, 3) 100% DC Resistance (DCR) & phase polarity testing, and 4) Final acoustic sweep inspection before packaging.

Yes, every production batch passes 100% electrical continuity and physical tolerance checks before boxing to guarantee zero defects upon arrival.

Yes, we strongly encourage sample evaluation. Pre-production samples can be shipped for acoustic testing and physical fitment verification prior to bulk production.

Yes. We welcome third-party inspection agencies (such as SGS, Bureau Veritas, or customer representatives) to inspect products at our warehouse before shipment.

Shipping, Lead Time & After-Sales

Standard models in stock can ship within 3–7 business days. Custom OEM orders typically require 15–25 days depending on tooling complexity and order volume.

We support global Express Air Courier (DHL, FedEx, UPS), Air Freight for urgent medium orders, and Sea Freight (FCL/LCL) for high-volume bulk cargo.

Both options work! We can deliver cargo to your designated freight forwarder warehouse in Guangzhou/Shenzhen, or arrange competitive door-to-door (DDP/DAP) international freight for you.

We stand behind our craftsmanship. If a verified manufacturing defect or transit damage occurs, please provide photos or videos within 14 days of receipt, and we will issue free replacements in your next batch or provide a mutually agreed resolution.

Yes. Our electro-acoustic specialists can assist with voice coil alignment guidance, cross-reference advice, and custom crossover pairing recommendations via WhatsApp or Email.

Simply send us the product specifications, desired quantity, target delivery location, or driver model through our online form or WhatsApp. We will reply with a detailed FOB/CIF quote within 12 hours.

Yes. Mixed-model orders are fully supported, making it easy for speaker repair centers and regional distributors to optimize inventory across multiple voice coil sizes.

Because we combine direct manufacturing controls, stringent quality testing, flexible OEM customization, and clear, fast communication to help global pro-audio brands lower costs and build reliable supply chains.
