Description
The CELTO CSW218V unleashes 2400W RMS (9600W peak) with brutally clean, deep bass that slams down to 34 Hz with authority. This dual 18" value subwoofer brings high performance to touring rigs and permanent installs while keeping the price firmly in the real world. Built for arenas, festivals, massive nightclubs, large halls, and any high-impact event where the low end must dominate without mercy. Twin premium custom CELTO high-excursion 18" drivers with 4" long-throw voice coils deliver relentless punch, speed, and effortless control. Heavily braced exterior-grade birch plywood cabinet with tongue-and-groove joints stays rock-solid even when pushed to the limit. 100 dB sensitivity and a calculated 141 dB peak SPL turn ordinary amplification into crowd-moving, structure-rattling force. Dual M20 threaded sockets and genuine Neutrik SpeakON connectors make cardioid arrays, stacking, and quick rigging child’s play. Touring-grade textured waterborne gloss-free black finish, with optional padded bag, crank pole bar, and heavy-duty castor kit for fast, road-ready deployment. The CSW218V proves that feel-it-in-your-bones bass can be outrageously powerful yet astonishingly affordable—no mercy, no regrets.
