A40 / A40T

4″ Passive Two-way On-wall Loudspeaker

The ADORN A40 / A40T is a two-way passive speaker with an elegant design that is perfect for architectural environments that require high-fidelity sound from an unobtrusive, ultra-compact enclosure. It brings class-leading performance, reliability and value to a wide range of commercial sound applications from retail outlets, bars and restaurants to corporate offices and convention centres.

The A40T and A40T-W incorporates a high-quality transformer for 70V/100V line operation, with transformer taps selected by a rotary switch.

The A40 is the perfect choice for background and foreground systems which require superior performance. Its Martin Audio signature sound characteristic also provides a seamless sonic transition within a multi-zoned complex using larger Martin Audio systems such as CDD or BlacklineX.

Comprising a 4 (100mm) LF driver and a 0.75 (19mm) silk-dome HF driver on a 110 x 80 horn, it handles 40W AES, 160W peak and can produce 109dB peak output at 1 metre. It has a smooth frequency response and strong bass reproduction that extends down to 70Hz.

With a nominal impedance of 16 ohms, multiple speakers can be driven in parallel from a single channel of a low impedance amplifier, thereby maximizing efficiency and minimising cost. For full-bandwidth protection, the low and high-frequency sections are individually protected against overload.

Available in black or white as standard, it can be readily painted to match any dcor, and can be wall-mounted vertically or horizontally using the wall bracket supplied. In addition, for general outdoor use the cabinet only requires the additional waterproof connector cover.
