The HXD-7501 is a 3-inch ultra-large-format titanium high-frequency compression driver — the undisputed flagship of the Hensinda Audio compression driver series. Engineered for the most extreme professional sound reinforcement applications on the planet, this driver features a massive 75mm aluminum flat wire voice coil, a high-strength titanium diaphragm, a 1.5-inch throat, and an exceptionally powerful ferrite magnet system. It delivers an astonishing 110dB sensitivity and 80W RMS power handling across a smooth 1–20kHz frequency response — establishing it as the ultimate high-output solution for the world’s largest line arrays, stadium PA systems, festival main stages, and the most demanding live sound environments imaginable.

The HXD-7501 represents the absolute pinnacle of Hensinda’s electroacoustic engineering capability. Every component has been meticulously engineered and selected to deliver the power, clarity, projection, and long-term reliability required for the most prestigious touring productions, Olympic-grade stadium installations, and world-class permanent sound systems.

✅ Key Features & Benefits

• Industry-Leading Sensitivity (110dB @ 1W/1M) – Extraordinary sensitivity delivers massive acoustic output with moderate amplifier power, dramatically reducing system amplification costs and maximizing dynamic range and headroom for the world’s largest venues.
• Ultra-High Power Capacity (80W RMS) – The massive 75mm voice coil with aluminum flat wire winding and advanced thermal management system ensures exceptional reliability even under extreme high-power operation in the most demanding live sound environments.
• Extended Frequency Response (1–20kHz) – Seamless integration with large-format mid-bass drivers, covering the full critical vocal and high-frequency spectrum with exceptional clarity, projection, and natural reproduction.
• Titanium Diaphragm – High-strength titanium provides superior stiffness-to-weight ratio, delivering fast transient response, extremely low distortion, and outstanding durability at extreme SPL levels exceeding 130dB.
• Large Voice Coil (75mm / 3″) – The massive CCAW (copper-clad aluminum wire) voice coil with flat wire technology maximizes copper fill ratio, reducing moving mass while maintaining high conductivity and exceptional power handling.
• 1.5″ Throat – Larger throat diameter enables higher acoustic output with reduced compression and lower distortion at extreme SPL levels, providing superior high-frequency extension and coverage control.
• Heavy-Duty Construction – 170mm overall diameter with 63mm depth, built with industrial-grade materials and precision engineering for decades of reliable service in touring and fixed installation applications.
