    About this Product

    The Martin Audio ADORN ACS-40TS is a 4″ enclosed ceiling speaker with a shallow backcan, designed for flush-mount installation in ceilings with limited cavity depth. Its exceptionally wide 180° conical coverage makes it particularly effective in low-ceiling environments, reducing the number of speakers needed for even coverage across retail, hospitality, corporate and leisure spaces.

    Flexible Drive Options

    The ACS-40TS supports 70V/100V line operation via its integrated transformer, with taps selected by a rotary switch behind the perforated steel grille. The switch also provides a 16-ohm low-impedance setting, allowing four or more speakers to be driven in parallel from a single amplifier channel.
