Martin Audio A55T ADORN 5.25-Inch Passive Two-Way On-Wall Loudspeaker with 70/100V Transformer, Black (Pair)

The Martin Audio A55T ADORN loudspeaker is built to deliver high-fidelity performance while maintaining an elegant and unobtrusive appearance. It fits seamlessly into architectural environments where superior sound quality is required without drawing attention to the speaker itself. Consequently, it is a perfect choice for retail outlets, bars, restaurants, corporate offices, and convention centers.

Overview

The ADORN A55T is a two-way passive speaker engineered with precision to offer class-leading reliability and value. It comprises a 5.25-inch (135mm) low-frequency driver and a 0.75-inch (19mm) silk-dome high-frequency driver, both designed to work together on a 110° x 80° horn for wide and even sound coverage.

This model handles 50W AES and 200W peak power, delivering a maximum SPL of 113dB at 1 meter. It produces a smooth frequency response with strong bass output that extends down to 65Hz, making it suitable for both background and foreground music applications.

70V/100V Line Operation

In addition, the A55T features a high-quality transformer for flexible 70V/100V line operation. Transformer taps can be quickly selected using a rotary switch, allowing installers to match the speaker output to different system requirements. This makes the loudspeaker highly adaptable for distributed audio systems in commercial environments.

Protection and Reliability

For durability, both the low-frequency and high-frequency sections are equipped with individual overload protection. This ensures dependable operation even in demanding installations where speakers may run for long hours every day.

Stylish and Versatile Design

Available in black or white, the A55T blends effortlessly with modern décor. Furthermore, it can be painted to match any interior design theme. The included wall bracket supports vertical or horizontal mounting, giving installers flexibility in placement.

For outdoor environments, the cabinet only requires an additional waterproof connector cover, allowing the speaker to adapt to a broader range of spaces.

Recommended System Pairing

When paired with the VIA5002 amplifier and a Martin Audio DX0.5 controller, the A55T becomes an ideal solution for small-scale installations. Larger and more complex setups can be managed using the DX4.0 controller, which integrates with Martin Audio’s VU-NET control software platform for centralized system control.

Additionally, the Martin Audio SX110 subwoofer can be added to extend low-frequency performance, providing a deeper and more impactful sound—especially useful for foreground music applications.
