RCF SUB 9019-AS 4000W 19″ High-Power Active Subwoofer – Black

RCF SUB 9019-AS 19-inch active touring subwoofer

The RCF SUB 9019-AS is engineered as a premium high-output active subwoofer designed for professional touring and large-scale sound reinforcement applications. It delivers exceptional low-frequency performance with a maximum sound pressure level of up to 138 dB, driven by an ultra-efficient 4000W Class-D amplifier. This combination ensures powerful, controlled, and articulate bass reproduction even under extreme operating conditions.

At the core of its performance is a 19-inch high-excursion precision transducer designed to handle deep bass frequencies with high linearity and accuracy. Despite its compact footprint compared to traditional large-format subwoofers, it produces impactful low-end response with minimal distortion. The advanced amplifier section incorporates a low-distortion signal path with integrated safety limiters, ensuring consistent output and protection during demanding live use.

The SUB 9019-AS integrates RDNet networked control, allowing real-time monitoring and system optimization including EQ, delay alignment, cardioid configuration, and preset management. It also features RDTap contactless configuration technology, enabling engineers to load or inspect system presets even when the unit is unpowered, significantly simplifying setup workflows in touring environments.

Designed for rugged use, the cabinet is constructed with durable plywood and coated with a weather-resistant polyurea finish. A rain cover protects the I/O panel from environmental exposure, while powerCON TRUE1 TOP connectors ensure reliable power delivery. The unit includes ergonomic handles and a detachable front cart option for improved mobility during transport.

Additional engineering features such as BMC (Bass Motion Control), ACE crossover presets, and factory-tuned system integration allow precise alignment with RCF full-range speakers. The SUB 9019-AS is optimized for modern touring systems requiring high output, flexibility, and intelligent remote control integration.
