Every detail of the Sub Series has been carefully studied in order to offer musicians and professionals the perfect tool to amplify their performance, night after night. High quality materials, precise manufacturing, careful assembly and extensive quality control procedures complete the ground-breaking design work of the RCF R&D team.
All transducers are precision built taking advantage of RCF's superior moulding, assembly technologies and a wealth of professional knowledge and experience dedicated to achieving extremely high standards. All the transducers in Sub Series speakers feature high power magnets in order to guarantee the best performance and power handling.
Sub Series Subwoofers are equipped with a new generation of Digital Amplifiers. The result of this is very high output, extremely low distortion and an incredible natural sound. The amplifier features a solid mechanical aluminium structure that not only stabilize the amplifier during transportation but also assist in the heat dissipation.
The input section provides:
- In/Out XLR connector
- Crossover Output XLR connector
- System sensitivity control
- Multiple crossover set-up
- Delay set-up
- Cardioid set-up
- 3 status LEDs
RCF RDNet 3.0 Monitoring and Management Network
The new RDNet release features extensive improvements. The audio system is now configurable in Groups of speakers or in the new Array clusters, the Air Compensation and the Cluster Size shaping are more precise and controllable, as well as the FiRPHASE gain. The subwoofer configuration is faster, even for complex EndFire set-ups.
Top End Electronics
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 RDNet Networked Management software. The available control panel on the back adjusts input sensitivity, Low Cut, Xover, volume, bypass, delay and presets selection. The regulated power supply guarantees full power from 100 V to 260 V. The amplifier houses on a unique Vibrostop floating aluminium panel for extra protection during transportation.
Hyper Ventilation System
RCF manufactures these components to deliver the cleanest, punchiest, and undistorted low frequencies reproduction. The cone is composed of 30% carbon fibre, 20% fibreglass and 50% cellulose pulp. This particular chemical composition has been carefully developed to improve the robustness and rigidness of the cone avoiding any deformation that would result in a loss of efficiency. The 4.0" inside/outside voice coil is wounded on a strong fibreglass former and guarantees a more efficient cooling. The former is internally and externally reinforced with Nomex that stiffen the overall structure for a better energy transfer between the voice coil and the body cone. In order to dissipate the heat generated by the powerful voice coil, RCF engineers have developed the unique Hyper Ventilation system with very low power compression. The cone is water resistant.
Cabinet
The cabinet is made of high-quality birch plywood with weatherproof treatment. The subs are stackable and lightweight, 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 withstand 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.
