Martin Audio A55 ADORN 5.25-Inch Passive Two-Way On-Wall Loudspeaker, Black (Pair)

The ADORN A55 is a two-way passive loudspeaker crafted for architectural environments that demand high-fidelity sound in an unobtrusive, ultra-compact enclosure. It brings class-leading performance, long-term reliability, and exceptional value to a wide variety of commercial applications. Consequently, it is often seen in retail outlets, bars, restaurants, corporate offices, and convention centers, where clear and consistent audio is essential.

Product Overview

The A55 features a 5.25-inch (135mm) LF driver paired with a 0.75-inch (19mm) silk-dome HF driver mounted on a 110° × 80° horn. Together, they deliver excellent sound dispersion, which ensures that audio remains clear and evenly distributed throughout the room.

This compact loudspeaker handles 50W AES and 200W peak, producing an impressive 113dB maximum SPL at 1 meter. Moreover, its smooth frequency response and strong bass performance extend down to 65Hz, providing a balanced listening experience suitable for background or foreground music.

Installation Efficiency & System Integration

Since the speaker has a nominal impedance of 16 ohms, multiple units can be driven in parallel from a single amplifier channel—such as the Martin Audio VIA2004—resulting in enhanced system efficiency and reduced cost.

Additionally, for full-bandwidth protection, both the LF and HF sections include individual overload protection, ensuring dependable performance in demanding environments.

Design Flexibility

The A55 sports a sleek, modern design available in black or white, and it can be readily painted to match any décor. Furthermore, the included wall bracket allows for vertical or horizontal mounting, making it adaptable to a wide range of installation scenarios.

For general outdoor use, the cabinet simply requires an additional waterproof connector cover, making it suitable for sheltered exterior environments as well.

Audio System Compatibility

The A55 integrates seamlessly with Martin Audio system components. The VIA2004 amplifier combined with the DX0.5 controller is ideal for smaller installations. In contrast, larger and more complex setups may require the DX4.0 controller, which can also be managed using VU-NET control software for advanced system configuration.

For enhanced low-frequency performance, pairing the A55 with the Martin Audio SX110 subwoofer extends its bandwidth, making it perfect for foreground music applications that require higher impact and richer bass.
