RCF SUB 905-AS MK3 - 2200W 15-inch Powered Low Frequency Subwoofer with 3-inch Voice Coil in Black Finish

The RCF SUB 905-AS MK3 is a high-performance, self-powered extended low-frequency subwoofer designed for demanding live sound applications. Equipped with a state-of-the-art 15" transducer, the subwoofer features a 3.0" voice coil and a ceramic magnet for excellent power handling and minimal distortion. This subwoofer is powered by a 2200W Class-D amplifier, capable of delivering sound pressure levels up to 133 dB, ensuring impressive bass reproduction even in large venues. The internal DSP and Bass Motion Control processing provide extended linearity and remarkable sound integrity, making the SUB 905-AS MK3 ideal for both live sound and DJing applications.

The 15" woofer is engineered for maximum performance, featuring a magnetic circuit optimized for high integrity and low distortion. The T-pole design minimizes flux modulation, ensuring a balanced and clean output with minimal distortion, even during heavy excursions. This transducer design, combined with the powerful 2200W amplifier, ensures that the SUB 905-AS MK3 can handle extreme sound pressure levels without sacrificing clarity or accuracy. The Class-D amplifier operates with high efficiency and very low heat loss, eliminating the need for a cooling fan. The amplifier is mounted to a solid aluminum heat exchanger, which enhances heat dissipation and ensures reliable performance during long hours of operation.

The rugged all-wood cabinet is coated with a durable polyurea finish, ensuring resistance to scratches and long-term wear and tear. The cabinet is lightweight, easy to carry, and stackable, making it perfect for portable applications. The subwoofer is designed with a pole mount receptacle on top and side, allowing for flexible configurations in various setups. The front grille is powder-coated and integrates a transparent-to-sound foam backing that protects the transducers from dust and other debris while allowing for optimal sound transmission.

On the rear panel, the SUB 905-AS MK3 offers comprehensive control options, including selectable gain, crossover frequency, polarity, and cardioid mode. It also features a time delay function for precise alignment with other speakers in a system. The stereo XLR input and output connectors allow for easy integration into a variety of sound systems, while the advanced safety limiter ensures the input signal remains true to its source, maintaining the integrity of the audio signal at all levels. The subwoofer's efficient design and versatile features make it an excellent choice for small to medium-sized venues, and it is also compatible with other RCF systems for larger applications.
