RCF ND940 140W AES 1.4" Compression Driver 8 Ohm

Description

The RCF ND940 is a high-performance 1.4-inch exit compression driver designed for professional touring systems, high-powered PA speakers, and premium installation applications. Engineered for exceptional clarity and output, it combines advanced materials and precision Italian manufacturing to deliver detailed high-frequency reproduction with excellent reliability under demanding conditions. The ND940 is well suited for use in two-way or three-way systems where high sensitivity, low distortion, and extended high-frequency response are required.

At the heart of the ND940 is a 4.0-inch edge-wound aluminum voice coil mounted on a titanium former, driven by a powerful neodymium magnet assembly. This design ensures high efficiency, reduced weight compared to ferrite alternatives, and excellent thermal management. The pure titanium diaphragm provides smooth and extended response while maintaining durability at high power levels. The driver’s precision-engineered phase plug optimizes airflow and minimizes distortion, resulting in clear, intelligible sound even at high SPL.

The RCF ND940 features a 1.4-inch throat exit and is designed to couple with standard 1.4-inch horn flares. It delivers a nominal impedance of 8 ohms and handles 140 watts AES continuous program power. The frequency response extends from approximately 500 Hz to 20 kHz, allowing for flexible crossover design in professional loudspeaker systems. With a sensitivity of approximately 110 dB, it provides strong output with minimal amplifier power, making it an efficient choice for high-performance systems.

The driver has a compact yet robust construction with a net weight of approximately 2.72 kg, offering an excellent balance between strength and portability for touring applications. Its advanced suspension design and precision assembly contribute to consistent performance and long-term reliability in demanding environments.

Overall, the RCF ND940 compression driver is a premium solution for system designers and manufacturers seeking high output capability, low distortion, and reliable operation in professional sound reinforcement systems.
