ND driver 1 Audio Compression Driver

Product Description

This is a 1-inch exit compression driver designed for high-performance audio applications. It features a 25.4 mm (1 in) exit throat and uses a 44.4 mm (1.7 in) aluminum ribbon (ALR) voice coil wound on the outside for efficient heat dissipation and durability.

The driver uses a polyimide (PI) diaphragm and suspension, offering a balance of rigidity and reliability at high frequencies. A neodymium magnet provides strong magnetic flux in a compact, lightweight structure; while a plastic phase plug, helps control wave propagation for improved high-frequency performance.

With a rated impedance of 8 ohms and an AES power rating of 50 W (100 W program), the driver is suited for professional sound reinforcement. It delivers a sensitivity of 107 dB (1 W/1 m) and covers a frequency range of 120019,000 Hz, making it ideal for high-frequency sections of loudspeaker systems.
