The RCF NX 12-SMA is equipped with new high power 700 W digital amplifier and a newly designed 12” coaxial neodymium transducer that guarantees outstanding audio quality and definition as well as an extremely lightweight of the final system.
The NX 12-SMA can be also used as a portable PA system, thanks to the rugged powder coated steel pole mount installed on the side. In order to control the response of the speaker in such different applications, RCF has incorporated two special Equalization Modes:
- Floor, for stage monitoring;
- Free Field, for the use of the speakers as a stand-alone PA system.
Cabinet is 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 of the speaker.

Coaxial neodymium trasducers

The newly designed coaxial neodymium transducers guarantee an outstanding audio quality and definition as well as an extremely lightweight of the final system.

Complete absence of feedback

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 NX Coaxial Stage Monitors are provided with brand new digital amplifiers with powerful DSP processing. A 400 W module that delivers 300 W for the low frequencies and 100 W for the high frequencies powers the NX 10-SMA. The NX 12-SMA and NX 15-SMA are equipped with a 700 W amplifier, 500 W feed the low frequencies and 200 W are used for the high frequencies.
