The Martin Audio Adorn ACS 55TS ceiling speaker (each) is designed for commercial environments that require high-quality sound diffusion and discreet integration.
Featuring a 5.25-inch woofer and a 0.75-inch silk dome tweeter, it delivers a nominal power of 50 W RMS with a frequency response ranging from 117 Hz to 20 kHz.
Thanks to its 150° directivity, this speaker ensures homogeneous sound coverage, reducing the number of units required for an efficient installation, particularly suitable for spaces with low ceilings.

The Martin Audio Adorn ACS 55TS is also equipped with a multitap transformer for 70V and 100V lines, allowing easy adjustment of the powers via a rotary selector accessible behind its perforated steel grille, accessible even after flush mounting.
It can operate in low impedance mode at 16 ohms, which offers great flexibility in installation, especially in configurations where multiple speakers are connected to a single amplifier.

For easy installation, the Adorn ACS 55TS comes with mounting rails and a C-bracket, while its borderless grille and clean white design allow it to blend seamlessly into any decor.
Its small footprint makes it ideal for environments where aesthetics are as important as sonic performance, while being compatible with Martin Audio's recommended VIA 2004 amplifier for maximum efficiency.
