The AD-S4T features a high-quality 4\" weather-treated paper cone woofer on a 1\" voice coil. It also has a 0.75\" silk dome tweeter with a 0.75\" voice coil. The consistent and even 120° axisymmetric (conical) coverage is achieved through DMT (Directivity Matched Transition), which matches the directivity patterns of the woofer and the high-frequency waveguide at the crossover point. The even and accurate frequency response of the AD-S4T is maintained even in 70\/100V applications by use of a low-loss, low-saturation 30W transformer with selectable taps, including an 8-ohm bypass. The rotary selector is located on the back of the enclosure, protected by a weather grommet. Featuring a rugged ABS enclosure, sealed input panel cover, and powder-coated aluminum grille, the AcousticDesign surface-mounted speaker exceeds IEC60529 IP-54 ratings for dust and splash resistance.\u003c\/p\u003e\r\n\u003cp\u003eThe two-way surface-mount loudspeaker includes the X-Mount system for easy installation. Knurled surfaces at the pivot planes ensure the load will not drift or sag over time. Articulation marks allow pre-configuration of the X-Mount while on the ground with no special tools required. Voicing filter sets using QSC Intrinsic Correction techniques are obtainable via Q-Sys networked audio processing platforms, including CXD amplifiers (sold separately). For your system integration needs, complete EASE, CF2, CAD, and BIM files are available for download on the QSC website.\u003c\/p\u003e\r\n\u003ch3\u003eFeatures\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e4\" Weather-treated woofer; 0.75\" silk dome tweeter\u003c\/li\u003e\r\n\u003cli\u003e120°
