The QSC AcousticDesign™ AD-C6T is a
6.5" two-way ceiling loudspeaker ideally
suited for a wide variety of foreground and
background sound reinforcement
applications which utilize 70/100V or 16Ω
bypass configurations.
The AcousticDesign™ Series offers
integrators a premium quality installed
sound solution where performance,
consistent coverage, and aesthetics are
paramount. Specifically designed to
maintain a consistent tonal characteristic
across the entire family in ceiling, surface,
and pendant applications, the
AcousticDesign series allows integrators
seamless transitions within blended
installations.
The AD-C6T features a high quality 6.5"
weather treated paper cone woofer with a
1" voice coil and a .75" aluminum dome
tweeter which is positioned on a DMT
waveguide.
DMT (Directivity Matched Transition™) is
QSC’s design philosophy where the high
frequency waveguide is matched to the
natural conical behavior of the woofer at the
crossover point. The result is a coherent
transition between transducers with
improved off-axis power response for
consistent 135° conical DMT coverage.
snap-fit magnetically attached powder coat
steel grille.
To retain lasting good looks, the rugged
ABS baffle is further protected by using UV
inhibitors that prevent discoloration and by
a powder coated steel back can. The
magnetic grille features a stick-on logo that
can be removed blemish-free for
installations where branding is not
permitted.
Installers will appreciate the 3x double
stepped, long travel dog-ear blind mounting
system, which captures from 0" - 2.25" of
ceiling thickness. The conduit cover plate
can be easily removed by losening the
single captive Phillips screw allowing access
to the locking 4-pole Euro-block connector
which can accept up to four 18AWG pairs,
eliminating the hassles of star topology
wiring designs.
Intrinsic Correction™ voicings that optimize
performance and speed the install process
are easily deployed via the Q-SYS
Platforms, including CXD-Q Series
amplifiers, as part of a complete QSC
systems solution.
The AD-C6T is available in QSC standard
black (RAL 9011) or white (RAL 9010) and
may be painted to match any decor.
The accurate frequency response of the
AD-C6T is maintained even in 70/100V
applications by use of a low-loss, lowsaturation 60-watt transformer with
selectable taps, including 16Ω bypass,
using a rotary selector located under the
