18 Sound HD1050 – High-Performance 1-Inch HF Compression Driver for Exceptional Clarity and Power
The 18 Sound HD1050 is a professional-grade high-frequency compression driver designed to deliver superior sonic performance across a wide frequency range. Engineered in Italy by 18 Sound—one of the most trusted names in transducer innovation—the HD1050 is crafted for demanding applications where clarity, power, and reliability are paramount. Whether you’re designing a new loudspeaker system or upgrading your current rig, the HD1050 offers premium high-frequency performance in a compact and robust package.
This driver is an ideal solution for compact two-way systems, professional studio monitors, and touring-grade PA setups. With its refined acoustic response, high sensitivity, and rugged construction, the HD1050 consistently delivers brilliant highs with outstanding detail and precision.
Precision Engineering for Clear, Accurate Sound
The HD1050 features a 44 mm (1.75-inch) edge-wound aluminum voice coil and a 25 mm (1-inch) throat exit, allowing it to reproduce high frequencies with remarkable accuracy. Thanks to its specially developed titanium diaphragm, the HD1050 offers exceptional transient response and clarity, ensuring intelligibility in vocal reproduction and detail in instrument playback.
Its frequency response extends from 1.6 kHz to 20 kHz, covering the entire critical high-frequency spectrum. Whether you’re amplifying speech, music, or ambient effects, the HD1050 ensures that every detail is projected with precision.
High Sensitivity and Efficient Performance
With a sensitivity of 107 dB (1W/1m), the HD1050 is incredibly efficient, delivering high SPL levels without the need for massive amplifier power. This makes it ideal for professional touring systems where output and energy efficiency are both essential. Its high sensitivity also contributes to a more dynamic, open, and lifelike sound, especially when used in combination with high-quality mid and low-frequency drivers.
Innovative Phase Plug Design
A standout feature of the HD1050 is its proprietary phase plug design, optimized for smooth and coherent wavefront propagation. This innovation improves acoustic coupling with a variety of horn designs and helps maintain consistent off-axis response, which is essential for high-quality coverage in larger venues or open spaces.
The phase plug enhances the driver’s ability to produce a flat, natural frequency response while minimizing phase cancellation and distortion at crossover frequencies. This allows the HD1050 to seamlessly integrate into multi-driver speaker systems with excellent results.
Robust Ferrite Magnet for Lightweight Durability
The HD1050 is built with a compact and efficient ferrite magnet assembly, dramatically reducing weight while maintaining strong magnetic flux and performance. This lightweight construction is perfect for portable systems and flown arrays where weight and size are critical factors.
Despite its compact design, the driver delivers 50W AES power handling and 100W program power, ensuring consistent performance even under continuous professional use. The voice coil is thermally bonded and cooled efficiently through a vented design, reducing power compression and extending the driver’s life.
