RCF’s SUB 9004-AS Now Shipping

RCF’s single 18” high power active subwoofer, SUB 9004-AS, is now shipping. Employing a state of the art transducer featuring a hypervented high power neodymium magnetic circuit with 4” voice coil, the design features a new ventedport which reduces air turbulence. The extremely high power amplifier is also a new design that delivers extended low frequency performance. Due to its rugged construction it is perfect for AV rental inventories and reliable installations, both indoor and outdoor.

The amplifier integrates a low-noise 32-bit DSP circuit, controlled through the RCF proprietary RDNet network to easily handle the soft clipping limiters, RMS limits, polarity, amplitude, timing and equalisation. All the settings, monitoring and advanced features are available inside the integrated RDNet Networked Management software. The encoder on the back adjusts volume, delay and presets.

RDNet is a proprietary protocol for RCF products that provides straightforward monitoring and intuitive control of the audio system down to every device/object. Each device has its DSP, giving the possibility to address specific presets or parameters change to single or groups of objects. A network user can change level, delay, EQs and other parameters, including advanced subwoofer configurations. Not only loudspeakers: it is possible to control routing and parameters of multiple RCF devices, like digital matrixes or amplifiers.

RCF manufactures these components to deliver the cleanest, punchiest, and undistorted low frequency reproduction. In order to dissipate the heat generated by the powerful voice coil, RCF engineers have developed a unique internal ventilation system with very low power compression. The Hyper Vented System is the result of a complex combination of ventilation ducts in the voice coil former, in the magnetic structure and in the woofer’s basket. In addition, the demodulation rings reduce the harmonic and intermodulation distortion associated with the voice coil displacement and, as input current varies, the system inductance is more linear. The cone is water resistant.

The cabinets are made of high-quality birch plywood with weatherproof treatment. The subs are stackable and light weight, for an easy set-up and tear down. A pole receptacle on the top and side allows the woofer to be used in various configurations. The heavy-duty coating and the rugged structure of the cabinet withstands long-term use and transportation and the separate housing for the amplifier guarantees component efficiency and reliability. Transportation is fast thanks to the detachable Kart kit: a dolly caster-board with rugged tour grade casters and rotating cam mechanism.

The SUB 9004-AS can be matched with the HDL 30-A — where up to four modules can be stacked on top (horizontal placement), or the HDL 10-A where four can be stacked on top (vertical placement).
