RCF SUB 18-AS Active 18-Inch Subwoofer – 2200W
The RCF SUB 18-AS is a powerful active 18-inch subwoofer designed for live sound, DJs, production companies, venues and professional AV applications. Built around a high-performance 18-inch woofer with a 4-inch voice coil, it delivers tight, controlled low end with serious punch and clarity.
With a 2200W Class-D amplifier and up to 135 dB max SPL, the SUB 18-AS is made to deliver strong bass performance while remaining practical for portable PA systems. It is an ideal companion for 10-inch, 12-inch and 15-inch full-range speakers, helping add depth, impact and low-frequency extension to a professional sound system.
Powerful 18-Inch Bass Performance
The SUB 18-AS uses a high-performance 18-inch woofer with a 4-inch voice coil, giving it the output and control needed for demanding live sound applications. Whether used with a mobile DJ rig, live band PA, venue system or AV production setup, it delivers deep, musical bass with excellent definition.
2200W Class-D Amplifier
Powered by a 2200W Class-D amplifier, the SUB 18-AS provides plenty of headroom for professional use. With up to 135 dB max SPL, it is capable of producing strong low-frequency output while keeping the sound controlled and reliable.
Bass Motion Control Technology
RCF Bass Motion Control, also known as BMC, helps manage woofer excursion more effectively than conventional high-pass filtering. By continuously monitoring cone movement, the system allows the woofer to operate efficiently while maintaining reliability and control.
The result is deeper bass extension, improved transient response and higher usable output without introducing unwanted distortion.
Built for the Road
The SUB 18-AS is built using a premium birch plywood tour-grade cabinet with a durable polyurea protective coating. This makes it suitable for hire companies, mobile entertainers, venues and production crews who need equipment that can handle regular transport and real-world use.
Ergonomic side handles make the subwoofer easier to move, while the integrated M20 pole mount allows full-range satellite speakers to be mounted directly above the sub for a clean and practical PA setup.
Flexible System Connectivity
The SUB 18-AS includes stereo XLR/TRS combo inputs with link outputs, along with stereo XLR crossover outputs. This makes it easy to connect into a wide range of PA systems, whether you are running a compact stereo setup or building a larger sound reinforcement rig.
Onboard controls include adjustable volume, polarity and low-pass filter settings, helping you match the subwoofer to your speakers and room more effectively.
