High-Power 18_ Subwoofer Performance
At the core of the RCF SUB708ASMK3 is an 18_ woofer with a 3.0_ voice coil, designed to deliver extended bass response from 35 Hz to 120 Hz. Its 1400W peak and 700W RMS power output provides impressive low-frequency energy, while the Class-D amplifier delivers fast transient response, high efficiency, and reliable performance without fan noise.
With a maximum SPL of 133 dB, this subwoofer offers the output required for DJs, live bands, venues, schools, houses of worship, and event production professionals needing clean, powerful bass reinforcement.
Advanced Bass Motion Control and DSP Protection
RCF?s Bass Motion Control technology helps maintain woofer stability while preserving low-frequency extension and sound integrity. Instead of relying on traditional high-pass filtering that can alter phase behaviour, BMC intelligently manages woofer excursion for cleaner, more natural bass reproduction.
The processor section includes thermal and RMS protection, a soft limiter, volume control, EQ, phase adjustment, and crossover control, giving you the flexibility to tune the subwoofer for different rooms, speaker pairings, and performance environments.
Tour-Ready Cabinet Design
Built from Baltic birch plywood with a rugged black finish, the SUB708ASMK3 is designed for regular transport, venue installation, and demanding live use. Side handles make setup and pack-down easier, while the pole mount allows convenient pairing with compatible top speakers.
Its steel grille with clothing helps protect the driver, while convection cooling and VDE power connection support dependable operation during long performances and event schedules.
