Martin Audio A55 ADORN 5.25" On-Wall Speaker (White)
The A55 is the larger of Martin Audio's two ADORN on-wall speakers, a two-way box combining a 5.25" low-frequency driver with a 0.75" silk-dome tweeter. The extra cone area over the A40 gives it more low-end body and level, making it a good foreground choice for bars, restaurants, showrooms and worship spaces that want fuller sound from a still-discreet wall-mount box.
It handles 50W AES (200W peak) at 16 ohms nominal and reaches 113dB peak, with a wide 110-degree by 80-degree pattern. The standard version runs low-impedance; the A55T adds an internal 70V/100V line transformer for distributed installs. It ships in white with a matching bracket. Response runs 90Hz-17kHz.
