Thirty years ago we began our journey to bring music to the masses through portable audio. Our goal was simple but ambitious: to design lightweight, active speakers that were not only portable, but also provided sound quality limited to bulky, heavy speakers.
SUB 8003-AS MK3 is a subwoofer with an extended low frequency range with its own power supply and internal DSP processor. Its compact housing houses a state-of-the-art 15-inch ceramic magnet driver and 3.0-inch voice coil. The internal amplifier supports an output power of up to 2200 W, providing a sound pressure level of up to 133 dB. Proprietary Bass Motion Control processing ensures extended linearity and extraordinary sound integrity. Rear panel controls include presets, crossover frequency and polarity selection, cardioid and output delay settings. Ready for the road, the rugged all-wood chassis with a scratch-resistant polyurea coating is stackable and lightweight for quick assembly and disassembly. Built specifically for highly demanding applications, the SUB 905-AS MK3 is the ideal workhorse for professionals dealing with music.
Powerful Class D amplifiers
RCF's Class D power amplifier technology combines massive efficiency and high efficiency in a lightweight solution. RCF amplifiers deliver ultra-fast attack, realistic transient response and impressive sound quality. The amplifier features a solid, machined aluminum construction that not only stabilizes the amplifier during transportation, but also helps dissipate heat without a fan. All amplifiers feature an SMPS power section that provides maximum output power and minimum weight.
Legendary subwoofers
RCF subwoofers are the first choice of many audio engineers, thanks to very high SPL levels at very low frequencies, small dimensions compared to the competition, self-powered design, internal delay control, long-term reliability, cardioid configuration options and impressive size/weight to output ratio SPL. Your crowd will be able to experience an immersive, immersive experience in both live sound and DJ applications.
Industry leading subwoofers
Light and powerful, RCF woofers are the benchmark in high performance. RCF Precision Transducers engineers developed new, specific magnet sizes and forms to optimize magnetic flux while maintaining low weight. The 15-inch, 3.0-inch diameter voice coil magnetic circuit topology is capable of providing the highest, balanced level of performance in three specific areas: maintaining a consistent, high-integrity magnetic flux gap, extremely low distortion, and efficient magnetic circuit integration with minimal design weights. Optimizing the T-pole design generates a minimum amount of flux modulation in the magnetic assembly during typical motion of the voice coil in the slot.
The power that moves
The most powerful amplifier in its class. RCF improvements in driver design make our woofers stronger and more powerful, so the amplifier follows the evolution. With 2200W of power, our Class D amplifier is able to handle extreme sound pressure levels with ultra-fast attack, realistic transient response and very low heat loss. So energy efficient that there's no need for a cooling fan - the amplifier is attached to a solid aluminum heat exchanger on the back of the chassis - with no moving parts. The stereo crossover input circuit features a new low-distortion design and advanced safety limiter, maintaining the true character of the input signal at all levels. RCF amplifiers are designed in accordance with the EN62368-1 standard to ensure maximum safety and feature a switching power supply section combining high performance with minimum weight.
Everything is ready for departure and work
RCF enclosures are made of high-quality multi-layer hardwood with a black polyurea finish. The bases are stackable and lightweight, making them easy to assemble and disassemble thanks to the ergonomic handles. A pole slot on the top and side allows the box to be used in a variety of configurations. The powder-coated front grille contains a special sound-transparent foam inside that further protects the drivers from dust
