Martin Audio A40 ADORN 4" On-Wall Speaker (White)
The A40 is the smallest of Martin Audio's ADORN on-wall speakers, a two-way box pairing a 4" coated-paper cone with a 0.75" silk-dome tweeter in a compact moulded enclosure. It is built to sit unobtrusively on a wall in cafes, meeting rooms, retail and hospitality spaces, delivering clean foreground music and speech from a footprint that stays out of the way.
It handles 40W AES (160W peak) at 16 ohms nominal and reaches 109dB peak, with a wide 110-degree by 80-degree pattern for even coverage close to the wall. The standard version runs low-impedance; the A40T adds an internal 70V/100V line transformer for distributed systems. It ships in white with a matching bracket. Response runs 98Hz-17kHz.
