Martin Audio ADORN A55T 5.25″ 2‑Way Speaker (Black) with Wall Bracket

Overview

The Martin Audio ADORN A55T is an ultra‑compact, passive two‑way on‑wall speaker featuring a built‑in 70/100 V line transformer and included wall bracket. It is engineered for both commercial and professional installations requiring discreet, high‑fidelity sound in applications such as retail outlets, cafés, restaurants, hotels, conference venues and corporate offices.

Design and Build Quality

The enclosure is constructed from UL 94V‑0 rated ABS for fire resistance and durability. The perforated steel grille adds protection and aesthetic refinement. Inside, the 5.25″ low‑frequency driver uses a coated‑paper cone with rubber surround and high‑temperature voice coil, while the 0.75″ silk‑dome tweeter is mounted on a horn for consistent 110 degrees × 80 degrees dispersion. This layout delivers precision, clarity and wide coverage from a compact form factor.

Key Technologies and Features

• Front‑ported bass reflex: Extends low‑frequency response down to ~65 Hz for richer sound in background and foreground music applications.
• Passive crossover with auto‑resetting fuses: Protects the LF and HF drivers from overload without interrupting performance.
• Rotary transformer switch: Offers selectable power taps at 70 V and 100 V lines--30 W, 15 W, 7.5 W (and 3.75 W at 70 V).
• Wide dispersion horn pattern: Ensures even coverage across the listening area, minimising hotspots or nulls.
• IP54 optional weather‑resistance: Easily upgradeable with a connector cover for protected outdoor installation.
• Vertical/horizontal mounting bracket: Included for flexible placement and alignment.

Specifications

Performance and User Experience

In real‑world use, the A55T delivers clean, intelligible audio with adequate bass for ambient or light music, and offers consistent coverage across listening zones. The small size allows installation in tight spaces without compromising output. It is built for reliability, with protective fusing and a robust enclosure suited to long‑term professional use. For integration in larger systems, it pairs well with Martin Audio VIA2004 or VIA5002 amplifiers and is manageable via the DX-series controllers and VU‑NET platform. For increased low‑end impact, pairing with an SX110 subwoofer is recommended for foreground music applications.
