Martin Audio Adorn A40W – 4" On-Wall Loudspeaker, White Pair
Product Overview
The Martin Audio Adorn A40W is a compact two-way passive on-wall loudspeaker designed for commercial background music and distributed audio systems. Sold as a pair in white finish, it delivers 109dB peak SPL from an ultra-compact enclosure with a 110° x 80° horn-loaded coverage pattern. The A40W suits retail, hospitality, corporate, and educational environments where an unobtrusive, high-performance wall-mounted loudspeaker is required at an accessible price point.
Product Description
The Martin Audio Adorn A40W is acoustically identical to the A40B, differentiated by its white finish for installation in light-coloured interior environments. The white enclosure coordinates with the ACS-40TS-W ceiling speaker and ACS-55T-W ceiling range for a unified system aesthetic in mixed wall-and-ceiling deployments.
Driver complement includes a 4" (100mm) LF driver and a 0.75" (19mm) silk-dome HF driver on a 110° x 80° horn, producing 109dB peak SPL at 1 metre with bass extension to 70Hz and 40W AES power handling. With 16-ohm nominal impedance, multiple A40W speakers can be run in parallel from a single low-impedance amplifier channel. Both driver sections carry independent auto-resetting overload fuses. For outdoor use, an optional waterproof connector cover is all that is required. View all Martin Audio products at Creation Networks – Martin Audio.
