C-120 (CX-System)

FIRTEC-equalizer, impulse true, coaxial reference monitor of the highest quality

The CX-Coaxial system is a modular system comprised of different but harmonized components. The main fields of application are sound studios from classic to rock recordings, video and film studios. The scalable size facilitates an adaption to the existing control room, just as our RC-100 remote control allows filter adjustments to adapt the listening area. The compact cabinet of the cube with an edge length of 45cm also facilitates mobile applications.

KSdigital manufactures each of its loudspeakers by hand in its factory Saarbrücken/Germany. Each loudspeaker is measured individually (IFM) and linearized in frequency and phase. This ensures the unrivalled correct reproduction of the music signal.


The C120-Coax is a two-way full range loudspeaker which, when connected to the digital FIRTEC equalizer permits linear phase, neutral amplitude and time-aligned reproduction. It is equipped with a 12" bass-mid chassis whose core accommodates a 1" compression driver. This radiates to a computer optimized CD-horn that evenly floods the entire working area. The C120-Coax covers the entire range from 25Hz to 22KHz or can be combined, depending on the size of the room, with bass systems of the CX series.

The Acoustic Advantages of the C120:

- Phase locked coupling of the radiated sound to input signal
- Point sound source
- Extremely compact cabinet size with a full bandwidth from 25Hz upwards.
