{"product_id":"rcf-nd850-2","title":"RCF ND850 Compression Driver 3-Inch Pure Titanium Diaphragm | 2\" Exit","description":"\u003cp\u003eThe RCF ND850 compression driver series is built for system integrators, touring engineers, and OEM cabinet builders who demand consistent high-frequency performance across demanding live sound and installed audio applications. Using a precision-formed 0.05mm pure titanium diaphragm on a 3-inch voice coil, the ND850 family reproduces high-frequency content with low coloration from 500 Hz through 20 kHz, making it a reliable choice for line array replacements, point-source enclosures, and custom installs where driver longevity and spectral consistency are critical.\u003c\/p\u003e\u003cp\u003eEach driver in the series employs an edgewound aluminum voice coil on a high-temperature Kapton former, a copper demodulation ring for extended upper-frequency response, and a 3-slot optimized geometry phase plug for even wavefront loading into the horn throat. The aluminum rear cover and front adaptor ensure a controlled transition from the phase plug to the exit interface, preserving pattern integrity before the horn. The vented suspension design reduces distortion under sustained high-level program material, keeping the driver dependable through long performance days or continuous commercial playback.\u003c\/p\u003e\u003cp\u003eThe ND850 range is offered in 1.4-inch and 2-inch exit throat versions, giving engineers flexibility to match the driver to existing horn inventory or new cabinet designs without adapters. CE compliance confirms the drivers meet European safety standards, and the ceramic and neodymium magnet options across the family allow builders to optimize for weight, flux density, and budget within a single proven diaphragm platform.\u003c\/p\u003e","brand":"RCF USA, Inc.","offers":[{"title":"2\" Exit","offer_id":52451862053048,"sku":"75761","price":569.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/75761_RCF-ND850-Compression-Driver-3-Inch-Pure-Titanium-Diaphragm-_-2_-Exit_ALT01sqr.jpg?v=1786583042","url":"https:\/\/soundpro.com\/products\/rcf-nd850-2","provider":"SoundPro","version":"1.0","type":"link"}
