Deep impact — the CELTO ACS218 unleashes a commanding 3000W RMS (6000W Peak) with profound, controlled low-end down to 30 Hz in a compact, self-powered dual 18" design. This high-performance subwoofer perfectly complements ACS10 arrays, delivering seamless extension for dynamic, musical bass in any configuration. Suited for live music, corporate events, auditoriums, houses of worship, entertainment venues, and portable systems requiring powerful yet precise reinforcement. Twin custom 18" die-cast woofers with 4" PI-grade voice coils and Kevlar-loaded cones provide exceptional excursion and clarity. Integrated 4th-generation Class D amplifier with DSP (crossover, EQ, phase, limiter) and presets (Flat/Punch/Deep) ensure optimal performance and protection. Heavy-braced Baltic birch plywood cabinet with tongue-and-groove assembly and touring-grade rubberized PolyUrea finish stands up to rigorous use. Calculated 139 dB peak SPL with smart thermal management for sustained high-output operation. Balanced XLR in/thru and PowerCon connectivity make integration truly plug-and-play. The ACS218 proves that earth-moving bass can be both devastatingly deep and elegantly compact—no need to sacrifice space for seismic results
