SUB 8003-AS MK3 Overview: The SUB 8003-AS MK3 is a self-powered extended low-frequency subwoofer with internal DSP. Housed in a compact cabinet, it features an 18" transducer with ceramic magnets and a 4.0” voice coil. The internal amplifier manages up to 2200W power output, delivering sound pressure levels up to 135 dB. Proprietary Bass Motion Control processing ensures extended linearity and remarkable sound integrity. Rear panel controls include presets, crossover frequency, polarity selection, cardioid, and output delay settings. The tour-ready, rugged all-wood cabinet with scratch-resistant polyurea coating is stackable and lightweight, ensuring quick setups and tear-downs. Built specifically for highly demanding applications, SUB 8003-AS MK3 is the perfect workhorse for music professionals.

Legendary Subwoofers: RCF subwoofers are the top choice of many sound engineers due to their high SPL levels at low frequencies, compact dimensions, self-powered design, internal delay control, long-term reliability, cardioid configuration options, and an impressive size/weight to SPL output ratio. Your audience can enjoy an engaging immersive experience in both live sound and DJing applications.

Industry-Leading Subs: Lightweight and powerful, RCF woofers are a reference in high performance. RCF Precision Transducers engineers have optimized magnet sizes and molds to enhance magnetic flux while maintaining low weight. The 18", 4.0" voice coil magnetic circuit topology delivers balanced performance, ensuring a consistent, high integrity magnetic flux gap, exceptionally low distortion, and efficient integration of the magnetic circuit in a minimal weight design. T-pole design optimization minimizes flux modulation during typical voice coil movement within the gap.

Power That Moves: The most powerful amplifier in its class. RCF's improvements in transducer design make their woofers stronger and more powerful, allowing the amplifier to follow the evolution. With 2200W power, the Class-D amplifier manages extreme sound pressure levels with an ultra-fast attack, realistic transient response, and very low heat loss. Energy-efficient without the need for a cooling fan - the amplifier is attached to a solid aluminum heat exchanger in the rear of the cabinet - with no moving parts. The stereo input circuit with crossover features a new low distortion design with an advanced safety limiter, maintaining the true character of the input signal at all levels. RCF amplifiers are designed according to EN62368-1 for maximum safety and present a Switch Mode Power Supply section joining high efficiency with minimum weight.

Tour-Ready Workhorse: RCF cabinets, made of high-quality multi-ply hardwood coated with a black polyurea finish, are stackable and lightweight for easy setup and teardown, facilitated by ergonomic handles. A pole receptacle on top and side allows various box configurations. The powder-coated front grille integrates a special transparent-to-sound foam backing to protect transducers from dust.
