Compact Size, Exceptional Performance

Despite its modest footprint, the A40-W delivers class-leading performance across a wide variety of commercial environments. Because of its precise acoustic engineering, this loudspeaker is ideal for:

• Retail stores

• Restaurants and cafés

• Bars and lounges

• Corporate offices

• Conference centers

• Reception halls

• Public spaces that require reliable sound with minimal visual impact

With a 4-inch LF driver and 0.75-inch silk-dome HF driver, the A40-W provides a balanced tonal output. The 110° × 80° horn ensures broad and even coverage, making speech and music clear throughout the room.

Strong Output and Smooth Frequency Response

The A40-W handles 40W AES and 160W peak, achieving a peak SPL of 109dB at 1 meter. Its smooth frequency response, extending down to 70 Hz, ensures warm low-end performance and detailed highs. This makes it suitable for ambient background music as well as more dynamic foreground applications.

Flexible Installation and Attractive Design

With its modern and unobtrusive appearance, the A40-W integrates effortlessly into any interior. Because it comes with an included wall bracket, it can be mounted vertically or horizontally depending on room layout and sound dispersion needs.

Additional benefits include:

• Paintable ABS enclosure for design customization

• Optional waterproof connector cover for general outdoor use

• Rugged construction suitable for long-term installations

Efficient 16-Ohm Impedance for Multi-Speaker Installations

The A40-W has a 16-ohm nominal impedance, enabling installers to connect multiple speakers to a single amplifier channel. This reduces equipment costs and increases system efficiency. When paired with the Martin Audio VIA2004 amplifier and DX0.5 or DX4.0 controller, the A40-W delivers optimized performance with advanced system management via VU-NET software.
