It employs a state of the art transducer featuring a hypervented high power neodymium magnetic circuit with 4\" voice coil. The extremely high-power amplifier is a new design that delivers extended low frequency performance. Due to its rugged construction, it is perfect for AV rental inventories.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNetworked Control and Much More\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRDNet 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.\u003c\/p\u003e\n\u003cp\u003eUsers 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-Quality Electronics\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe power amplifier features an integrated, low-noise 32-bit digital signal processor that allows convenient control of soft limiting, RMS limiter, polarity, volume, time delay, and tone controls via RCF's proprietary RDNet network. The RDNet network management software provides access to all settings, monitoring functions, and advanced features. The rear panel offers adjustments for input sensitivity, low-cut filter, crossover frequency, volume, bypass, delay, and preset selection. The wide-range power supply ensures full power output from 100V to 260V. The amplifier is mounted on floating rubber dampers, providing additional protection against shocks during transport.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHyper-Ventilation System\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRCF designed these components to achieve the cleanest, most powerful, and distortion-free bass reproduction possible. The cone diaphragm is made of 30% carbon fiber, 20% glass fiber, and 50% cellulose. This special chemical composition was carefully balanced to improve the diaphragm's robustness and rigidity, preventing deformation and the resulting loss of efficiency. The inside\/outside wound 4-inch voice coil on a rigid fiberglass former ensures more efficient cooling. The former is reinforced internally and externally with Nomex, further increasing the overall rigidity and improving energy transfer between the voice coil and the diaphragm. To better dissipate the heat generated by the high-performance voice coil, RCF engineers developed the unique \"Hyper-Ventilation\" system with minimal power loss. The speaker diaphragm is water-resistant.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHousing\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe enclosure is constructed from high-quality birch plywood. Each layer is bonded with a special waterproof adhesive, making the enclosure completely weatherproof. The subwoofers are stackable and lightweight, and easy to set up and take down. Top and side mounting flanges allow for use in various configurations. The removable dolly with extremely robust casters facilitates transport.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAcoustical Data:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 30 Hz, 400 Hz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMax SPL @ 1m:\u003c\/strong\u003e 136 dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTransducer:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWoofer:\u003c\/strong\u003e 1 × 18\" Neodymium, 4\" voice coil\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput \/ Output Section:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Signal:\u003c\/strong\u003e Balanced \/ Unbalanced\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Connectors:\u003c\/strong\u003e XLR, RDNet Ethercon\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Connectors:\u003c\/strong\u003e XLR, RDNet Ethercon\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Sensitivity:\u003c\/strong\u003e +4 dBu\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProcessor \/ Control:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-Pass Frequencies:\u003c\/strong\u003e 35 Hz, 50 Hz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLow-Pass Frequency:\u003c\/strong\u003e Variable, 50 Hz, 400 Hz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProtection Circuits:\u003c\/strong\u003e Thermal, RMS\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLimiter:\u003c\/strong\u003e Fast Limiter\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eControls:\u003c\/strong\u003e Gain, EQ, Preset Switch, Output Delay\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNetwork Control:\u003c\/strong\u003e RDNet Onboard\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAmplifier Section:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTotal Power:\u003c\/strong\u003e 2800 W Peak \/ 1400 W RMS\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCooling:\u003c\/strong\u003e Forced Air\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConnections:\u003c\/strong\u003e PowerCON IN\/OUT\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompliance:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSafety Certification:\u003c\/strong\u003e CE Compliant\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhysical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCabinet Material:\u003c\/strong\u003e Baltic Birch Plywood\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHardware:\u003c\/strong\u003e 2 × M20 Threaded Sockets\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHandles:\u003c\/strong\u003e 2 Side Handles\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePole Mount \/ Cap:\u003c\/strong\u003e M20 Thread\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrille:\u003c\/strong\u003e Steel\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Height:\u003c\/strong\u003e 700 mm \/ 27.56 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Width:\u003c\/strong\u003e 558 mm \/ 21.97 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Depth:\u003c\/strong\u003e 700 mm \/ 27.56 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 57 kg \/ 125.66 lbs\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Height:\u003c\/strong\u003e 770 mm \/ 30.31 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Width:\u003c\/strong\u003e 770 mm \/ 30.31 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Depth:\u003c\/strong\u003e 630 mm \/ 24.8 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e 61.8 kg \/ 136.25 lbs\u003c\/p\u003e","brand":"RCF","offers":[{"title":"Default Title","offer_id":53509722210485,"sku":"H-RCF-SUB9004AS","price":6999.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/3208\/3637\/files\/2096975.jpg?v=1791818722","url":"https:\/\/hollywoodpro.com\/products\/rcf-sub9004-as-subwoofer","provider":"Hollywood Pro","version":"1.0","type":"link"}
