Product Description

RCF S4012

The S4012 high-efficiency band pass subwoofer is the ideal bass frequency extension to complement the RCFACUSTICA Compact series two-way loudspeakers for small size installations and distributed music systems.

The low-frequency transducer is an RCF Precision high-power 12” woofer with a 3” inside/outside voice coil to minimize power compression and extend the life of the product.
This new woofer design guarantees a fast and controlled reproduction of the bass frequency range. Using bandpass loading to the transducer, the subwoofer design ensures an efficient acoustic response down to 45 Hz.
The cabinet features two Neutrik Speakon™ connectors in a recessed input plate.
