The RCF SUB 8004-AS is a powerful 18-inch active subwoofer engineered for high-output live sound. Its 18-inch woofer with a 4-inch voice coil in a bass-reflex enclosure delivers tight, deep lows with a commanding 136 dB max SPL. A robust onboard digital amplifier supplies 1250 W RMS (2500 W peak), while DSP functions include a fast limiter, integrated delay and cardioid presets for precise, adaptable system tuning. Built from rugged Baltic birch plywood with a durable black finish, it’s ready for the road and everyday rental duty. Practical features such as a pole mount, compact 700 x 557 x 700 mm footprint and a manageable 51 kg weight allow flexible pairing with point source or line array tops. This package includes the original RCF protective cover, Bluewheels castors for easy transport and a PowerCON power cable, so you’re set for quick deployment and reliable protection. Ideal for live music, corporate events and mobile production where tight, controlled bass extension is required.
