C3110-126 TWO WAY PASSIVE SPEAKER SYSTEM
DESCRIPTION C3110-126 belongs to RCF ACUSTICA - NEW COMPACT SERIES and is a full range extremely versatile wide-dispersion, low-profile, two-way loudspeaker system offering substantial power and efficiency for several professional applications that include permanent installations, main reinforcement in small spaces, plus portable systems and supplementary fill for larger systems. Its compact size makes it ideal for low visibility side wall or under balcony mounting. RCF 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 a 10” 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 a new 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).
