FAQ

What material is the speaker diaphragm made of? Is it durable?

Titanium – Offers superior stiffness-to-weight ratio, delivering fast transient response, extremely low distortion, and outstanding durability at extreme SPL levels exceeding 130dB. Ideal for high-output PA and stadium systems.
Polyimide – Provides an ideal balance of stiffness, lightness, and internal damping, delivering warm, natural tonality with reduced listening fatigue. Perfect for studio monitors and vocal-critical applications.
Polyester – Engineered for mid-range applications, offering excellent internal damping and smooth, natural vocal reproduction with high power handling capabilities.

All our diaphragms undergo rigorous durability testing, including accelerated life testing at rated power for 100 hours continuously. With proper system integration (correct crossover frequencies and amplifier limiting), our drivers deliver decades of reliable service in touring and fixed installation applications.

What scenarios are the speaker drivers suitable for?

Our compression drivers are designed to meet the needs of various professional audio applications.

Our engineering team can also recommend the optimal driver for your specific system design and acoustic requirements.

Is the quality of the speakers guaranteed?

Absolutely. Quality is our top priority at Hensinda Audio. Our quality assurance framework includes:

100% Incoming Material Inspection – All raw materials (magnets, diaphragms, voice coils, frames) are tested before production.
In-Process Quality Control (IPI) – Key parameters such as voice coil centering, adhesive curing profiles, magnetic gap precision, and excursion limits are continuously monitored via SPC.
100% Final Testing – Every driver is individually tested for impedance, frequency response, sensitivity, and distortion before packaging.
Full Traceability – Each production batch is fully traceable from raw materials to finished goods.
24-Month Warranty – All our drivers come with a 24-month warranty covering manufacturing defects in materials and workmanship under normal operating conditions.

We are also certified to comply with CE, RoHS, and REACH standards, ensuring smooth customs clearance and market access worldwide.

Can I customize the specifications or branding of the speaker drivers?

Yes, we offer extensive customization and OEM/ODM services for wholesale buyers:

Acoustic Customization:

Frequency response shaping and tuning
Impedance curve optimization
Custom crossover point recommendations

Mechanical Customization:

Custom mounting formats and terminal configurations
Frame design and cosmetic finishes

Material Selection:

Custom labeling and spec sheets

Please contact our sales team to discuss your specific requirements. For custom OEM/ODM projects, we provide full engineering support from concept validation, acoustic simulation, and prototyping to mass production.

What is the after-sales guarantee?

We provide comprehensive after-sales support for all our wholesale buyers:

24-Month Standard Warranty – Covers manufacturing defects in materials and workmanship.
Technical Support – Our engineering team provides assistance with frequency response tuning, crossover design consultation, impedance matching, and integration guidance for your specific audio system requirements.
Defect Compensation Program – For any quality issues confirmed on our side, affected units are replaced and shipped with your next order at no additional cost (rather than costly international returns).
Sample Support – We offer samples for testing and validation before bulk orders.
