Active Curvature System

Revolutionary plug-and-play performance—the CELTO Acoustique ACS combines the ultra-compact ACS10 curvature array with the powerful ACS218 dual-18" subwoofer to deliver arena-grade sound in a system small enough to fit in the back of a van. This fully self-powered line source system offers unmatched size-to-SPL ratio, with dynamic, crystal-clear coverage that scales effortlessly from intimate corporate events to energetic live music sets. The ACS10 (Master + Passive) uses patented IsoTop™ coaxial technology and integrated Class D amplification with advanced DSP for seamless coherence, precise directivity, and up to 136 dB peak SPL from A3-sized cabinets. Paired with the ACS218’s 3000W RMS built-in power and deep extension down to 30 Hz, the system provides tight, musical bass that perfectly complements the tops—whether pole-mounted, ground-stacked, or flown. Versatile deployment options include up to 6 ACS10 elements per array, with quick rigging and smart presets for near, mid, or far-field optimization. Premium Baltic birch construction with touring-grade rubberized PolyUrea finish ensures durability and reliability night after night. True plug-and-play connectivity—no external amps, no complicated setup—just power up and perform. Ideal for houses of worship, auditoriums, multifunctional rooms, portable DJs, corporate events, and live music venues demanding premium quality without the logistical headache. The ACS proves that exceptional sound doesn’t need massive cabinets or endless racks—just intelligent design and a little CELTO magic.
