The Martin Audio Adorn A40 is a compact and stylish, yet powerful two-way passive speaker designed for high-quality background audio.

The Martin Audio Adorn A40 is a stylish, modern and discrete wall-mounted passive speaker perfect for bars, restaurants, pubs and similar venues looking to add high-quality audio.

Their unique yet unobtrusive design and size make the A40's ideal when space is a premuim, and are a great option for low-ceiling areas. 

    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. 

    The Adorn A40's are available in black or white, but can be easily painted to match any décor, and can be wall-mounted vertically or horizontally using the wall bracket supplied.

    The A40 can also be used for general outdoor use using an additional IP44 waterproof connector cover.
