Atlas Sound’s FAP40T-B four-inch in-ceiling speaker system is part of the Strategy II Series in-ceiling speakers. Designed to provide high performance in a very compact footprint, the FAP40T-B is meant for high-intelligibility voice, music, and signal reproduction in commercial, industrial and institutional applications. A patent-pending tap selector switch design allows for easy system tuning. A full selection of taps up to 16 watts as well as an 8Ω transformer bypass setting is included for maximum system versatility. This switch “knob” also functions as a diffuser cone, providing smooth, even dispersion of the high frequency content from the center of the 4″ polypropylene driver. The grille and baffle are finished in black.
