The RCF SUB 8004-AS is a high-powered active subwoofer designed to deliver deep, controlled low-frequency reinforcement for professional audio systems. Its 18-inch woofer with a ventilated 4.0-inch voice coil is driven by a 2500 W peak (1250 W RMS) amplifier, generating up to 136 dB SPL with ample headroom. A wide 30–120 Hz frequency response provides solid extension and punch, making it an excellent partner for modern point-source and line array tops.
Onboard DSP offers a selection of practical presets for quick system voicing, while an integrated delay enables straightforward time alignment with mains in both single-box and distributed deployments. The robust birch plywood enclosure is built for touring use, combining durability with consistent acoustic performance. Professional connectivity and intuitive controls support fast, reliable setup across different venues and event types.
From live music and DJ events to corporate AV and fixed installations, the SUB 8004-AS adds authority, clarity and impact to any PA system, delivering the low-end foundation that keeps shows sounding tight and focused.
