RCF SUB 905-AS MK3 – Professional 15-inch active subwoofer
The RCF SUB 905-AS MK3 is a powerful and versatile active 15-inch subwoofer for professional sound systems. This compact powerhouse combines a high-quality 15-inch woofer with a powerful built-in amplifier of 2200 Watt Peak and 1100 Watt RMS. With a maximum sound pressure of 133 dB, the SUB 905-AS MK3 delivers an impressive amount of low end for its size.
The frequency range spans from 40 Hz to 120 Hz, making this subwoofer an excellent match for professional RCF top speakers. The powerful bass reproduction is ideal for DJs, bands, live performances, corporate parties, events, and mobile PA systems.
The integrated DSP ensures that the RCF SUB 905-AS MK3 can be precisely tuned to the rest of the sound system. Extensive settings include gain, EQ, phase, crossover, delay, and cardioid mode. This allows the subwoofer to be flexibly adapted to different rooms and applications.
The 15-inch woofer features a 3-inch voice coil and is designed for powerful and controlled low-frequency reproduction. The housing is made of sturdy plywood and fitted with a professional steel grille. Thanks to the M20 pole mount, a suitable top cabinet can easily be placed on top of the subwoofer.
With its relatively compact dimensions and professional performance, the RCF SUB 905-AS MK3 is an excellent choice for users who want high bass pressure but find a 15-inch system more practical than a large 18-inch subwoofer.
At SpeakerKoning, this RCF subwoofer is a strong choice for a professional, compact, and powerful PA setup.
