Description

Reference-grade performance in a deceptively compact cabinet—the CELTO CT12 G3 commands 600W RMS with breathtaking transparency and effortless dynamics. This flagship 2-way loudspeaker dominates near-field FoH, touring rigs, high-end installations, stage monitoring, and delay applications—with or without subwoofers. Engineered for demanding professional environments: concert venues, theatres, houses of worship, corporate events, and premium club systems. At its heart, a custom 12" LF driver with extended excursion pairs with the renowned 1.7" voice coil ACD44 compression driver on a precision 6th-order Polynomial rotatable horn (80°x50°). Touring-grade birch plywood enclosure with tongue-and-groove joints, heavy-duty textured finish, full M8 fly points, symmetrical monitor angles, and integrated pole mount. Delivering 97 dB sensitivity and a thunderous 131 dB peak SPL with pristine control across the spectrum. Sophisticated passive crossover and Right-Phase design guarantee flawless time alignment and wide, uniform dispersion. The CT12 G3 doesn’t just reproduce sound—it reveals every nuance with the authority only true reference monitors achieve.
