RCF ND950 1.4 - 280W 4-inch Titanium Compression Driver with 1.4-inch Exit Throat and 8-Ohm Impedance in Black Finish

The RCF ND950 1.4 is a high-performance, ultra-compact 4-inch diaphragm compression driver, designed to deliver exceptional sound quality in professional audio applications. Equipped with a 1.4-inch exit throat, this driver offers superior power handling and high efficiency, thanks to its advanced neodymium magnet assembly. This robust magnetic system ensures perfect control over the dome assembly's moving mass, resulting in improved transient response, greater efficiency, and reduced high-frequency distortion.

The ND950 1.4 features a 0.05 mm thick pure titanium dome that is paired with a high-strength Mylar suspension. The combination of these materials provides excellent durability and performance, while the high-temperature Kapton voice coil former ensures the driver can handle the heat generated during high power usage. Additionally, the edge-wound copper-clad aluminum wire used in the voice coil assembly allows for optimal power handling and efficiency. The driver also boasts a 4-slot optimized phase plug design that was developed through advanced computer-assisted modeling, which reduces air distortion and maximizes output for superior sound quality.

With a frequency range of 500 Hz to 20 kHz and a sensitivity of 110 dB, the ND950 1.4 compression driver is capable of delivering clear, powerful sound across a wide spectrum. The driver handles 280W of continuous program power at 8 ohms, making it ideal for integration in professional systems requiring high output and low distortion. Additionally, a copper inductance ring is precision-pressed onto the pole piece to further extend the frequency response and improve the driver's overall performance.

The ND950 1.4 is the smallest available 4-inch driver in its category, making it an excellent choice for space-limited installations where performance cannot be compromised. Its neodymium magnet assembly ensures high flux density, contributing to its compact size and powerful output. This driver's unique combination of features allows it to perform flawlessly in high-powered systems, including line arrays and point source applications.
