RCF SUB 18-AS 18” Active Subwoofer – 2200W Class-D

RCF SUB 18-AS – Professional 18” Active Subwoofer for Touring and Live Sound

Touring-Grade Bass for Professional Sound Systems

The RCF SUB 18-AS is a high-power professional active subwoofer designed for live sound engineers, DJs and event professionals who demand serious low-frequency performance with maximum reliability.

Massive 2200W Class-D Power

At its core is a powerful 2200W Class-D amplifier driving a high-performance 18” woofer with a 4.0” voice coil. This delivers thunderous bass with exceptional headroom and up to 135 dB SPL without distortion.

Bass Motion Control DSP

RCF’s proprietary Bass Motion Control technology intelligently manages woofer excursion, ensuring deep, controlled bass at any volume level. This allows the SUB 18-AS to maintain clarity and punch even in demanding environments.

Professional Connectivity and System Integration

The rear connection panel features mono/stereo combo XLR/TRS inputs, XLR link outputs and dedicated XLR crossover outputs. This makes it easy to integrate with full-range PA systems, mixers and active speakers.

Built for the Road

Housed in a rugged Baltic birch plywood cabinet with a scratch-resistant polyurea coating and steel grille, the SUB 18-AS is built for touring and heavy-duty use. Integrated side handles and an M20 pole mount make setup fast and secure.
