Overview
The Celto Acoustique CSW218V is a high-performance, dual 18-inch vented subwoofer system engineered for professional sound reinforcement, permanent installations, and demanding mobile applications. Delivering 2400 W RMS (9600 W Peak) power handling at a nominal impedance of 4 Ohms, it is built to satisfy rigorous acoustic requirements.
The enclosure houses two custom-designed CELTO 18SW1202-8 LF transducers featuring die-cast aluminum chassis and 4-inch (100 mm) long-throw voice coils. Operating within a frequency range of 34 Hz to 1500 Hz, it achieves an average sensitivity of 100 dB (1W/1m) and a maximum calculated SPL of 133 dB RMS (139 dB Peak), ensuring deep, precise, and impactful low-frequency reproduction. The heavily braced, tongue-and-groove exterior grade birch plywood cabinet minimizes internal resonances and is finished with a durable textured waterborne black coating, complemented by acoustic PU foam behind the front steel grille. Designed for active-only operation, the system features dual genuine Neutrik Speakon NL4MP connectors for secure signal transmission. Equipped with two M20 threaded sockets for versatile mounting options, the 76 kg CSW218V represents a robust and uncompromising low-frequency solution for premium audio projects.
