Description
Deep, visceral bass without the excess baggage—the CELTO CSW118 unleashes a commanding 1500W RMS (6000W peak) with clean, articulate low-end that reaches down to an impressive 34 Hz.
This high-performance vented subwoofer is engineered for serious bass reinforcement in main PA systems, whether touring rigs or permanent installations on small to large stages, indoors or out.
Ideal for stadiums, arenas, multifunctional venues, theatres, nightclubs, bars, and high-end karaoke rooms where powerful yet musical sub-bass is essential.
At its core, a premium custom 18" CELTO driver with ferrite magnet and long-throw 4" in/out voice coil delivers exceptional excursion and control.
Heavy-braced birch plywood cabinet with tongue-and-groove assembly ensures vibration-free performance even at maximum output.
97 dB sensitivity and a calculated 135 dB peak SPL provide room-shaking impact with minimal amplification strain.
Dual 20 mm threaded top hats and genuine Neutrik Speakon connectors make stacking, pole-mounting, and integration quick and reliable.
Touring-grade textured waterborne black finish and robust CNC construction guarantee durability in the toughest environments.
The CSW118 proves that earth-moving low end can be both devastatingly powerful and surprisingly refined—no tantrums required.
