QSC AD-S4T 4.5" Two-Way Surface Speaker

QSC AD-S4T 4.5" Two-way surface speaker, 70/100V transformer with 8Ω bypass, 120° conical (Black or White) (PER PAIR)

The QSC AcousticDesign™ QSC AD-S4T is a 4.5", 70/100V, 2-way surface mounted loudspeaker system, which is very well suited for background music applications requiring clarity and depth even at lower volume settings. 

The AcousticDesign Series is offering the integrators a premium quality installed sound solution where aesthetics, performance and consistent coverage are paramount. Designed specifically for maintaining a consistent tonal characteristic across the entire family in pendant, ceiling and surface enclosures, the AcousticDesign Series allowing integrators seamless transitions within blended installations.

The QSC AD-S4T featuring 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 performance and sensitivity 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.
