Designed for rigorous touring, the RCF SUB 9016-AS is a high-performance subwoofer with innovative features and and a durable, all-weather cabinet. The subwoofer's 4000W Class-D amplifier powers the custom 16" woofer which offers a 30 to 200 Hz frequency response and a whopping 137 dB of acoustic output. The articulate yet powerful bass can reproduce even the most subtle low-frequency variations.
The SUB 9016-AS features precision control thanks to RDNet network management, offering adjustable EQ, delay, cardioid options, and tailored crossover presets for RCF speakers. Innovative contactless configuration via RDTap allows for seamless setup even when the unit is unpowered, ensuring perfect integration every time.

RDNet
- RDNet is the RCF management software suite for Sound System Engineers. A robust management network for RCF devices, a line-array design tool, a monitoring platform, and a complete audio analyzer in one package.
- RDNet provides intuitive management of every connected device/object on the network. Network users can control all DSP settings inside any compatible device including advanced subwoofer configurations, from a single object to groups of objects.
- RDNet users can edit and create recallable presets for RCF devices.
RDTap
The RDTap app offers contactless communication with the subwoofer. Users can access preloaded presets to quickly configure RCF systems or optimize compatible speakers, subwoofers, and line arrays.
- RDTap enables contactless communication, offering setup management and parameter updates, even when the unit is unpowered. By tapping the RDTap logo at the back panel with a smartphone running RDTap, the app transfers to the unit every aspect of the defined setup, including preset configurations, equalization, mid-low compensation for line arrays, and precise delay and time alignment settings, so you can read the status of the speaker.
- This is especially convenient when upgrading your subwoofers and giving your old main system a new life, with the assistance of presets, EQs, delays, and management, via RDNet.
- Unlike other control technologies that operate over long distances, this solution focuses on near-field interactions, where security, precision, and unpowered operations before rigging are key. Data transmission occurs at close range, ensuring that changes are applied only when intended, without interference from further distances or external devices. This makes it a highly efficient and user-friendly way to manage the subwoofer’s settings and performance before setup takes place.
Advanced Crossover Engine (ACE)
- Pair your full-range speaker with RCF ACE-enabled SUBs and unlock your system's true potential.
- RCF’s proprietary Advanced Crossover Engine (ACE) is engineered to precisely match the time delay and align the phase on a broader range than the usual crossover frequency range between RCF subwoofers and FiRPHASE-enabled full-range speakers.
Drive the Rhythm of the Beat
- With 4000W of power, the Class-D amplifier can manage extreme sound-pressure levels with ultrafast attack, realistic transient response, and very low thermal loss.
- The stereo input circuit features a 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 switched-mode power-supply section that combines high efficiency with minimum weight.
Advanced Speaker Components
Advanced Precision Transducers
- SUB 9000 Series subwoofers incorporate the latest transducer technology from RCF's labs. Employing lightweight aluminum core coils, high-damping cellulose cone material, composite spiders, and a 4-layer inside-outside voice coil, the ultralong excursion moving mass gains high power with fast acceleration. Despite their small and lightweight footprints, SUB 9000 Series subwoofers produce powerful yet articulate bass, remaining true to even the most subtle low-frequency variations.
High-Class Neodymium
- Neodymium, a rare-earth material, enhances efficiency, power handling, and weight reduction. Using a 20% stronger magnetic field than typical neodymium grades, this new design enables precise control and higher force.
Tour Grade Solution
- Designed for rigorous touring, SUB 9000 Series subwoofers feature tour-ready, weatherproof plywood construction with a durable polyurea finish.
- The included magnetic rain cover protects the connection panel from rain and dust, while rugged powerCON TRUE1 TOP AC connectors ensure reliable power delivery in any environmental condition.
- Subs are stackable and lightweight, have ergonomic handles with rubber grips, and are designed for easy setup and teardown.
- M20 pole mounts on the top and side of the cabinet offer flexible top speaker placement.
- Connections for a detachable front cart are included, enabling easy transport on wheels (cart sold separately).
Bass Motion Control
- When searching for an extended bass with enhanced performance, RCF engineers found a way to remove the high-pass filter, replacing it with a forward-thinking approach. Introducing BMC (Bass Motion Control), the newly advanced woofer excursion management feature. A speaker equipped with BMC can handle the lowest audible frequencies without affecting the woofer stability, and with extended linearity and better sound integrity.
- The BMC method works by creating a complete map of the dynamic behavior of the woofer, to generate a custom algorithm that only limits overexcursions. This gives total freedom of signal reproduction to the transducer. Where high-pass filters normally protect the woofer motion from becoming destructive but change the phase behavior, the new BMC algorithm breaks conventional rules.
