Applications

Retail outlets
Cafes, bars and restaurants
Museums and Houses of Worship
Hotels, casinos and concourses
Transportation facilities
Boardrooms and reception areas

The ACS-40TS brings full-frequency response, consistent coverage and intelligibility to a wide range of architectural environments — from hotels and concourses to retail outlets, bars and restaurants.

Comprising a 4” (100mm) LF driver and a 0.75” (19mm) silk- dome tweeter, the ACS-40TS produces 108dB peak output at 1 metre and has a high-fidelity sonic character ideal for both music and speech reproduction. Its ported design delivers strong bass that extends down to 73 Hz.

The very wide 180° conical coverage of the ACS-40TS makes it particularly suitable for low ceilings and reduces the number of speakers required for even coverage — leading to a reduction in installation cost. It features a shallow backcan for installation in ceilings with a minimum cavity depth.

It incorporates a high-quality transformer for 70V/100V line operation, with transformer taps selected by a rotary switch accessible behind the powder-coated, perforated steel grille. The switch also provides for 16-ohm low impedance operation — enabling four or more speakers to be driven in parallel from a single amplifier channel. For full-bandwidth protection, the low and high-frequency sections are individually against overload by auto-resetting thermal fuses.

The grille is bezel-less for a clean look, its bayonet fitting is easy to remove without the use of tools and finished in white (RAL9016) to match ADORN on-wall loudspeakers and may also be painted to blend with any décor.

Architectural Specs

ACS-40TS

The loudspeaker shall be a wide-dispersion, two-way, in-ceiling system consisting of a 4” low frequency transducer and a 0.75” dome high frequency transducer mounted in a ported enclosure. The enclosure shall comprise a pressed steel backcan with a UL94V-0 fire-rated moulded baffle. The transducers shall be protected by a quick-release perforated steel grille.

Input and loop through connections shall be made via a ceramic connector located behind a fire-retardant steel cover.

The loudspeaker shall include a steel support ring and tile rails. A safety ring on the backcan shall enable direct attachment to the building structure as a secondary support.

Dispersion shall be 180° conical up to 10kHz. The on-axis frequency response shall be 106Hz-20kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 108dB peak calculated at 1 metre. Power handling shall be 40W AES, 160W peak.

The loudspeaker shall be equipped with a transformer for 70V or 100V line operation, with taps selected by a rotary switch on the front baffle. The switch shall also provide for 16 ohm low impedance operation of the loudspeaker. Low and high frequency sections shall be integrated by an internal 3.5kHz passive network, with auto-resetting LF and HF fuses to protect the drivers from overload.

Dimensions including the grille (OD x D) shall be 221mm x 115mm (8.7ins x 4.51ins). Backcan depth shall be 97mm (3.81ins). Weight shall be 2.2kg (4.8lbs).

The loudspeaker shall be the Martin Audio ACS-40TS.
