RCF C3108-126
C Series 2-Way Passive Speaker with 8" LF, 1" HF, 120° x 60° Horn

OUR PART #  C3108-126

RCF's C3108-126 belongs to their Acustica Series and is a versatile  full-range, wide-dispersion, low-profile, two-way loudspeaker system that offers substantial power and efficiency for professional applications such as permanent installations, main reinforcement in small spaces, as well as in portable systems and supplementary fill for larger systems.  Its compact size makes it ideal for low visibility side wall or under balcony mounting.

RCF's exclusive Constant Matching Design technology helps guarantee an optimal transition between the high frequency horn polar pattern and the low frequency woofer directivity.  The horn can be rotated, allowing to install the loudspeaker either vertically or horizontally.  The hi-frequency transducer is a 1" RCF Precision compression driver with a 1.5" voice coil for smooth, wide dispersion.  The low-frequency transducer is an 8" RCF Precision woofer with a 2" voice coil.

The system includes a high-level crossover network that features markedly lower (than conventional) induction values in series with the woofer.  This innovation is named LICC (Low Impedance Compensated Crossover) its benefits are delay reduction, reduced phase shift and superior transient response.  Dynamic high-frequency driver protection is accomplished with an RCF exclusive - Active Mosfet Compression Driver Protection System (AMCDP), chosen to complement the driver power curve.

The cabinet is made of Baltic birch (heavy duty painted) and allow different installation options, as it is equipped with top and bottom Multiplates for either wall or suspended mounting with chains.  Installation points are available on its rear panel as well.  The steel front grille is protected with a double layer polyurethane fabric.  The front RCF logo is easily rotatable.

Connections are made through two Neutrik Speakon NL4 connectors (audio input and parallel link output).
