Description
The RCF SUB 9007-AS is one of the most powerful 2x21” subwoofers in the field of live sound. Featuring two, high power, hyper-vented 21” neodymium woofers with 4.0” inside-outside voice coils, this cabinet deliver a serious amount of low frequencies. Powered by a 7200 W digital amplifier, the SUB 9007-AS can perform in the most demanding situations. The housing of the SUB 9007-AS match the RCF D-Line HDL 50 and HDL 20 array systems, enabling stacked systems matched a perfect combination.
Networked Control and Much More
RDNet is an advanced platform for the integrated monitoring and control of sound reinforcement systems – from small live productions and permanent installations to large-scale stadium systems. With a robust network architecture, RDNet combines system control, line array configuration, simulation, and comprehensive FFT audio measurements in a single, powerful software package.
Users and technicians can intuitively manage every device on the network, from individual components to multiple groups. The platform's flexible configuration tools enable full DSP control of compatible devices for precise system response at maximum speed. Users can view and adjust all critical settings in real time via a central interface.
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 aluminum 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.
Stacking HDL 50-A 4K or HDL 30-A
The cabinet is made of high-quality birch plywood with every layer glued by a special water-resistant adhesive weatherproofing the cabinet. The heavily braced internal structure of the cabinet survives long-term use and transportation. Two separate acoustic chambers for the woofers and separate housing for the amplifier guarantee the best components efficiency and reliability. Dual Stacking: horizontal to fit the HDL 50-A 4K while the vertical fits HDL 30-A (or 20-A).
Cabinet
The heavy-duty powder coated front grille integrates a central reinforcement bar and a special transparent-to-sound foam backing on the inside helps to further protect the transducers from dust. The subs are stackable and light-weight, for easy set-up and tear down. The SUB 9007-AS and SUB 9006-AS are equipped with 8 aluminum handles (4 per side) with ergonomic rubber handgrip. The transportation is fast with the detachable Kart kit: a dolly caster-board with rugged tour grade casters and rotating cam mechanism.
