RCF SUB 8008-AS 4,400W 2 x 18-inch Professional Powered Subwoofer

RCF SUB 8008-AS dual 18-inch active subwoofer

RCF SUB 8008-AS active subwoofer is engineered for high-end professional live sound applications including large concerts, festivals, clubs, and touring systems. It features an extremely powerful 4400W Class-D bi-amplification system combined with two high-performance 18-inch woofers, delivering massive low-frequency output with tight control and exceptional clarity up to 137 dB SPL.

Designed for demanding environments, it uses advanced high-power transducers with a 4-inch voice coil and optimized magnetic structure to ensure high efficiency, reduced distortion, and strong thermal stability. The system delivers deep, impactful bass performance with fast transient response and high headroom, making it suitable for high-energy live sound reproduction.

The rear panel provides extensive DSP control, including selectable crossover presets, polarity adjustment, Deep/Punch modes, cardioid configurations, and output delay settings. These features allow precise system tuning and flexible integration into complex sound setups, including line array systems and multi-sub configurations.

Bass performance is optimized for both power and control, ensuring consistent low-frequency response even at extreme output levels. The amplifier is highly efficient, fanless, and thermally optimized, using convection cooling and a rear-mounted aluminum heatsink for silent operation.

The cabinet is constructed from rugged multi-ply plywood with a durable polyurea coating for touring reliability. It includes ergonomic side handles for handling, M20 pole mounts for flexible stacking, and a heavy-duty steel grille with internal acoustic protection. Its design supports both vertical and horizontal deployment for versatile system configurations.
