DESCRIPTION NX Series maximum flexibility philosophy has been maintained for NX15SMA; it is possible, in fact, to use it as a portable PA system, thanks to the rugged powder coated steel pole mount installed on the side The newly designed 15”+1” coaxial neodymium transducers guarantee an outstanding audio quality and definition as well as an extremely lightweight of the final system The advantages of the coaxial transducers are the complete absence of feedback and, thanks to the coherent single spherical wave front with a perfect dispersion control, a perfect listening in every position. The design is powered from a large sized single neodymium ring magnet that provides an extremely high flux density and BL factor. The new hyper-vented aluminium basket and magnetic assembly design provide an excellent heat dissipation and lower power compression. Special air-forced ventilations are provided for voice coil, magnet assembly and basket. A 2,5” voice coil combined a strength fibreglass former and aluminium 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. The NX 15-SMA is equipped with a 700 W amplifier, 500 W feed the low frequencies and 200 W are used for the high frequencies. In order to control the response of the speakers in such different applications, RCF has incorporated two special Equalization Modes: Floor, for stage monitoring and Free Field, for the use of the speakers as a stand-alone PA system The input board is fully equipped in order to configure the stage monitors for any stage situation with XLR Input and Output Link, Jack Input, Volume, Input Sensitivity Switch, Free Field – Floor Switch, Status LEDs, Powercon AC Input and Output Link Cabinets are made in Baltic Birch plywood, finished with an extremely resistant paint for an extensive use on the road. An ergonomic side handle, integrated with the input panel, is provided for an easier transport.
