18 Sound HD1000 – Compact, High-Performance HF Compression Driver
The 18 Sound HD1000 is a compact, precision-engineered high-frequency compression driver designed for professional audio systems that demand powerful performance, crystal-clear sound reproduction, and long-term reliability. Built in Italy by 18 Sound—an industry leader in transducer innovation—the HD1000 delivers premium performance in a lightweight, durable form factor that makes it ideal for a wide range of audio applications.
Whether you’re designing a portable PA system, upgrading a stage monitor, or crafting a custom loudspeaker, the HD1000 offers exceptional high-frequency clarity and reliable operation, making it a trusted choice for both touring professionals and installation engineers alike.
Optimized for Clarity and Precision
The HD1000 is built with a 25 mm (1 inch) throat exit and features a 44 mm (1.75 inch) edge-wound aluminum voice coil. These specifications allow the driver to produce clear, detailed high frequencies while maintaining stability under demanding operating conditions. It uses a titanium diaphragm, chosen for its high thermal resistance and dynamic responsiveness, which contributes to exceptional transient accuracy and tonal clarity across the entire operating range.
With a frequency response range of 1.6 kHz to 20 kHz, the HD1000 delivers extended, smooth high-frequency reproduction that captures every nuance of vocals and instruments. Its finely tuned acoustic performance makes it a preferred option for professional-grade sound reinforcement systems.
High Sensitivity for Efficient System Design
One of the standout characteristics of the HD1000 is its high sensitivity rating of 109 dB (1W/1m). This efficiency allows sound designers to achieve powerful output with lower amplifier power, making it especially useful for portable PA and installed systems where energy efficiency and compact power setups are crucial.
Its sensitivity ensures a high-output signal that maintains tonal consistency across varying volume levels. Whether used in a small venue or a large outdoor setting, the HD1000 can project sound with clarity and reach.
Proprietary Phase Plug for Smooth Dispersion
A key feature of the HD1000 is its proprietary phase plug design, engineered to produce a coherent wavefront for accurate sound dispersion. This contributes to smooth, consistent coverage across the driver’s operating bandwidth, which is especially beneficial when paired with horn flares in line arrays or point-source enclosures.
The phase plug geometry minimizes interference and phase cancellation, leading to better off-axis response and seamless integration with other transducers in two- or three-way systems.
Ferrite Magnet for Lightweight Power
The HD1000 uses a high-grade ferrite magnet that reduces overall weight while maintaining a strong magnetic field for reliable performance. This makes the driver ideal for mobile and tour-grade speaker systems, where reduced weight contributes to easier handling, transport, and rigging.
With an AES power handling of 50W and a program power rating of 1000W, the HD1000 is built to perform under real-world conditions without compromising durability or sonic integrity. Its efficient heat dissipation and robust construction help prevent power compression, ensuring consistent sound quality over time.
