Description
Your neighbours will outright despise you (and you’ll secretly adore every complaint)—the CELTO CSW218V unleashes a monstrous 2400W RMS (9600W peak) with brutally clean, ultra-deep bass that slams down to 34 Hz with terrifying authority.
This no-compromise dual 18" value subwoofer brings flagship-level devastation 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 139 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.
