Newly designed 12’ coaxial neodymium transducers guarantee outstanding audio quality and definition in a lightweight system. The advantages of the coaxial transducers are the absence of feedback and perfect listening in every position. The design is powered from a large sized single neodymium ring magnet that provides high flux density and BL factor. The new hyper-vented aluminum basket and magnetic assembly design provide heat dissipation and lower power compression. A 2,5’ voice coil combined a strength fiberglass former and aluminum wire drives the mid-bass cone with high efficiency and a good extension. The 1,7” dome compression driver, loaded to a 60° conical waveguide, provides a clear vocal output and a perfect high frequency extension. The NX Coaxial Stage Monitors are provided with brand new digital amplifiers with powerful DSP processing. In order to control the response of the speakers both stage monitor or PA, RCF provides an Equalization Mode for each application.
