The AtlasIED FC104T is a compact 4" commercial speaker designed for distributed audio systems that need clear voice reproduction and smooth musical playback in a small-format package. Its high-compliance cone and broad coverage pattern make it well suited for background music and public address applications where even sound distribution matters across offices, retail areas, corridors, and similar spaces.

This model includes a built-in 70.7V transformer with selectable taps from 0.5W to 8W, giving installers practical flexibility when balancing speaker output across a constant-voltage system. The wide 135° dispersion helps reduce the number of loudspeakers required in low-level distribution designs, which can simplify layout planning in commercial environments. The FC104T is also UL1480 safety listed, making it appropriate for specified installation projects that require compliant life-safety related audio components.

For integrators working with Atlas Sound 4" grille options, the FC104T offers compatibility with a broad selection of matching grilles, supporting cleaner architectural integration. With 94 dB sensitivity and a frequency response of 150 Hz to 17 kHz, it is built for intelligible announcements and general-purpose foreground or background audio where compact size and dependable coverage are priorities.
