Description:
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.
