The QSC AcousticCoverage™ Series  
AC-C2T is a ceiling mounted 2.75” fullrange loudspeaker with 70/100V 
transformer, suitable for a wide variety of 
audio/video conferencing reinforcement, 
voice paging and background music 
applications.
AcousticCoverage™ Series is designed to 
offer integrators a cost effective solution for 
applications where voice reinforced 
coverage is of primary concern, while 
providing improved musicality often not 
seen in typical BGM class products.
A high quality 2.75 inch weather treated 
paper cone transducer provides a natural 
rise in high frequency extension for greater 
clarity in high ambient noise environments.  
With 170 degrees of conical coverage, the 
AC-C2T reduces the number of 
loudspeakers required for even coverage in 
low ceiling applications.
The easy to install blind mount assembly 
features a ported baffle which optimally 
tunes the powder coated steel backcan for 
added musicality, creating low frequency 
extension down to 70 Hz. To maintain this 
frequency response, the AC-C2T utilizes a 
variable tap 16 watt low saturation and low 
loss 70/100V transformer, accessible under 
the powder coated steel grill via a rotary 
selector which also includes an 8 ohm 
bypass setting.
To further enhance performance and speed 
of install with optimum result, advanced 
voicing filter sets using the Q-SYS™ 
Platform, including CXD Series amplifiers 
for a complete QSC systems solution.
Installers will appreciate the 4 pole 
Euroblock connector for loop thru wiring, 
located under a quick access swivel plate.  
Eliminating the termination hassles of star 
topology wiring designs, the generous 
Euroblock of the AC-C2T can accept four 
18AWG pairs. 
A safety tether tab is affixed to the 
adjustable conduit clasp plate for seismic 
sensitive installations. C-ring and tile rails 
are included with each pair packed 
assembly, complete with joining screws 
and cut-out template. 
The AC-C2T baffle and grill are QSC 
standard white (RAL 9010) to match 
complimenting QSC product families and 
includes UV inhibitors to prevent 
discoloration over time. The AC-C2T may 
also be painted to match any décor.
To assist in successful systems integration, 
complete EASE, CAD, and BIM files are 
available for download online.
