    AD-S4T

    AcousticDesign™ Series

    AD-S4T

    Features

    • DMT™ (Directivity Matched

    Transition) ensures smooth,

    uniform frequency response over

    the coverage area

    • X-Mount™ system enables

    the loudspeaker to be easily

    installed and deployed at

    a variety of angles with no

    slippage over time

    • Advanced voicing filter

    sets using QSC Intrinsic

    Correction™, available through

    either Q-SYS processing or CXD

    Series amplifier platforms

    The QSC AcousticDesign™ AD-S4T is a

    surface mounted 70/100V, 4.5" two-way

    loudspeaker system, ideally suited for a

    wide variety of foreground and background

    sound reinforcement applications.

    AcousticDesign™ series offers integrators

    a premium quality installed sound solution

    where performance, coverage, and

    aesthetics are paramount. Combined with

    unprecedented ease-of-installation and high

    weather resistance, the AcousticDesign™

    Series provides integrators a versatile and

    confident install solution.

    The AD-S4T features a high quality 100 mm

    [4 in] weather treated paper cone woofer

    on a 25 mm [1 in] voice coil. A carefully

    selected 19 mm [.75 in] silk dome tweeter

    with a 19 mm [.75 in] voice coil perfectly

    matches the sensitivity and performance

    of the woofer for outstanding full-range

    reproduction.

    Consistent and even 120° axisymmetric

    (conical) coverage is achieved through

    DMT™ (Directivity Matched Transition),

    a QSC innovation which matches the

    directivity patterns of the woofer and the

    high-frequency waveguide at the crossover

    point. The result is a coherent transition

    between transducers and improved off-axis

    response.

    The even, accurate frequency response

    of the AD-S4T is maintained even in

    70/100V applications by use of a low-loss,

    low-saturation 30-watt transformer with

    selectable taps, including an 8Ω bypass.

    To preserve weather resistance, the rotary

    selector is located on the back of the

    enclosure, protected by a weather grommet.

    With rugged ABS enclosures, sealed

    input panel covers, and powder-coated

    aluminum grilles for weather resistance, the

    AcousticDesign™ surface mounted series

    exceed IEC60529 IP-54 ratings for dust and

    splash resistance.

    Installers will appreciate the award-winning

    X-Mount™ system included with each

    full-range AcousticDesign™ model. This

    ingenious mounting solution achieves

    unprecedented ease-of-installation

    in horizontal, vertical, wall, or ceiling

    deployments. Knurled surfaces at the

    pivot planes ensure the load will not drift

    or sag over time. Articulation marks allow

    preconfiguration of the X-Mount™ while on

    the ground with no special tools required.

    Once secure, the loudspeaker installs in

    seconds, allowing the installer to work safer,

    smarter, and faster with repeatable results.

    To further enhance performance and speed

    of install with optimum result, advanced

    voicing filter sets using QSC Intrinsic

    Correction™ techniques are obtainable via

    the Q-SYS Platform including CXD Series

    amplifiers for a complete QSC systems

    solution.

    The AcousticDesign™ Series feature a

    stylish appearance free of obtrusive logo

    adornments for aesthetically sensitive

    installations. AcousticDesign™ surface

    loudspeakers are available in QSC standard

    black (RAL 9011) or white (RAL 9010) and

    may be painted to match any decor.

    For your system integration needs, complete

    EASE, CF2, CAD, and BIM files are available

    for download at QSC.com.
