DESCRIPTION

NX Series maximum flexibility philosophy has been maintained for NX10­SMA; 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 10”+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 10-SMA is equipped with a 400 W
amplifier, 300 W feed the low frequencies and 100 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.
