Martin Audio Adorn ACS-40TS-W – 4" Shallow Ceiling Speaker, White Pair

Product Overview

The Martin Audio Adorn ACS-40TS-W is a compact two-way passive ceiling speaker with a shallow backcan, designed for background music and distributed audio systems in commercial spaces with limited ceiling cavity depth. Sold as a pair in white, it features a 180° conical coverage pattern — the widest in the Adorn range — making it particularly effective in low-ceiling environments where maximising coverage from fewer fixtures is a priority. The 70V/100V line transformer and 16-ohm low-impedance operation ensure compatibility with the full range of commercial audio distribution systems.

Product Description

Part of the Martin Audio Adorn commercial loudspeaker series, the ACS-40TS-W addresses installations where ceiling cavity restrictions preclude standard-depth backcans and where low ceiling heights demand the broadest possible coverage angle to maintain even SPL distribution. The 180° conical pattern allows maximum fixture spacing, reducing the total number of speakers required per zone.

The two-way driver complement pairs a 4" (100mm) LF driver with a 0.75" (19mm) silk-dome tweeter, producing 108dB peak SPL at 1 metre with bass extension to 73Hz. The ported enclosure design delivers strong bass performance for a 4" format, suitable for general background music applications in most commercial environments. The white (RAL9016) bezel-less grille coordinates with the Adorn on-wall range. Tile rails and a C-ring for drop-ceiling installation are included.
