Audac ADC-ALTI4M/W - 2-way 4" Mount Loudspeakers - White.
The AUDAC ALTI4M is a surface-mount variant of the ALTI pendant speakers, designed for situations where hanging speakers just aren’t practical. With its robust die-cast wall & ceiling bracket, it lets you keep the same sonic character and visual identity across an installation, even in areas with low ceilings, tricky structures, or outdoor exposure.
Behind its compact, modern housing, the ALTI4M hides a carefully engineered 2-way coaxial design: a 4" low-frequency driver with a coaxially mounted 1" soft dome tweeter and an integrated phase plug for excellent off-axis performance. The polypropylene enclosure, aluminium grill, and AWX5™ waterproof connector deliver an IP65-rated speaker ready for indoor or outdoor use in demanding commercial and architectural projects.
With 30 W RMS (60 W program / 120 W peak) power handling and a wide 165° conical dispersion, the ALTI4M delivers clear, even coverage with fewer speakers, making it ideal for retail spaces, hospitality, houses of worship, corporate facilities, and outdoor patios.
