Description

Deep, authoritative bass meets surgical precision—the CELTO Acoustique CT15 G3 unleashes 800W RMS with visceral impact and crystalline highs that redefine large-venue clarity. This powerhouse 2-way system excels in medium-throw FoH, touring sound, permanent installations, floor monitoring, and side fills—standalone or reinforced with subs. Built for the most critical professional applications: live concerts, large theatres, auditoriums, arenas, and high-output club installations. A massive 15" LF driver with 3.6" voice coil teams with the acclaimed ACD44 compression driver on a rotatable 80°x50° 6th-order Polynomial horn for pinpoint coverage control. Heavy-duty birch plywood cabinet with reinforced construction, comprehensive rigging array, symmetrical monitor geometry, and robust pole socket. Achieving 98 dB sensitivity and a staggering 134 dB peak SPL while maintaining musical finesse at any level. Advanced crossover topology ensures perfect phase coherence and smooth off-axis response throughout the listening area. The CT15 G3 delivers the kind of effortless power and detail that makes audiences forget the speakers are even there—until they feel the impact.
