Description

The HXD-4402 is a 1.75-inch large-format high-frequency compression driver engineered for professional audio applications that demand smooth, natural sound reproduction with exceptional output capability. Featuring a 44.4mm aluminum flat wire voice coil and a high-performance polyimide diaphragm, this driver delivers outstanding 108dB sensitivity and 40W RMS power handling across a smooth 1–20kHz frequency response — making it an excellent choice for high-end PA systems, studio monitors, cinema sound, and premium installed audio.

The polyimide diaphragm offers a unique sonic character — delivering the transient response and detail of metal diaphragms with a warmer, more natural tonality that reduces listening fatigue during extended sessions. This makes the HXD4402 particularly well-suited for critical listening applications and vocal-centric sound reinforcement.

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.
