ND driver 1 .4 Audio Compression Driver

Product Description

This high-performance 1.4-inch exit compression driver is engineered for professional sound reinforcement systems requiring powerful, articulate high-frequency reproduction. It features a 36 mm (1.4 in) exit throat and a large 75 mm (3 in) voice coil constructed with CCAR (copper-clad aluminum ribbon) wound on the outside, ensuring excellent thermal handling and efficient power transfer.

The driver uses a titanium diaphragm paired with a PEK suspension, providing exceptional rigidity, extended high-frequency response, and reliable long-term performance. A robust neodymium magnet assembly delivers strong magnetic flux while keeping overall weight low, and an aluminium phase plug enhances acoustic loading and HF clarity.

With an 8-ohm rated impedance and AES power handling of 80 W (160 W program), the driver is suitable for high-output applications. It achieves a high sensitivity of 108 dB (1 W/1 m) and operates across a wide frequency range of 80019,000 Hz, making it an excellent choice for mid-high to high-frequency sections of professional loudspeaker systems.

Mechanical & Mounting Description

The driver features a sturdy and compact structure with an overall diameter of 124 mm (4.9 in) and a depth of 58 mm (2.3 in). It mounts easily using:

• Bolt circle diameter: 102 mm (4.0 in)
• Bolt holes: 4 M6 (0.24 in)

This configuration ensures compatibility with standard horn throats and mounting patterns used in professional audio installations.
