Overview
The Celto Pro ACS218 is a high-performance active subwoofer system designed for professional sound reinforcement, touring applications, and permanent installations. Equipped with dual 18" CELTO 18SW1201-4 transducers featuring Kevlar-loaded paper cones and 4" (100 mm) long-throw voice coils, it delivers a deep and controlled low-frequency response down to 30 Hz.
Powered by the 4th generation CELTO TrueSound proprietary Class D amplifier module (SPM3000S) with an aluminum heatsink, the system delivers 3000W RMS (6000W Peak) power, reaching a maximum calculated SPL of 139 dB. The integrated DSP architecture, utilizing 32-bit AKM AD/DA converters, provides precise control over crossover, EQ, phase, and limiting, alongside Flat, Punch, and Deep presets. Built for demanding environments, the heavily braced birch plywood enclosure is finished with a touring-grade rubberized PolyUrea coating and features M20 and M10 mounting threads. Distributed by Trioacoustic, the ACS218 offers uncompromising acoustic performance for premium venues and projects.
