Overview

The RCF SUB8006AS is a high-output active subwoofer engineered for professional audio environments where powerful, controlled bass is non-negotiable. At its core are dual 18-inch transducers paired with a built-in digital amplifier delivering 2500 watts RMS and 5000 watts peak. This combination produces a maximum sound pressure level of 141 dB, placing the SUB8006AS firmly in the category of large-format subwoofers designed for touring sound companies, major venue installations, and high-energy DJ events. The frequency response of 30 Hz to 120 Hz ensures deep, physically felt low-end reproduction without muddying the crossover region with mid-frequency content.

As an active subwoofer, the SUB8006AS integrates its amplification and processing internally, simplifying the signal chain and reducing the need for external amplifier racks and processing units. RCF's onboard DSP handles crossover management, limiting, and protection, allowing the subwoofer to operate at sustained high output without thermal or mechanical damage. The dual-driver configuration moves significantly more air than single-driver designs, resulting in tighter, more authoritative bass response at scale. This is a subwoofer purpose-built for professionals who need to fill large spaces with clean, powerful low-frequency energy and who have the infrastructure to support a cabinet of this class.
