QSC AD-C4T 4.5" Two-way ceiling speaker, 70/100v transformer (Black or White) (PER PAIR)

Description QSC AD-C4T 4.5" Two-way ceiling speaker, 70/100v transformer (Black or White) (PER PAIR) The QSC AcousticDesign™ AD-C4T is a 2-way, 4.5" ceiling loudspeaker very well suited for a wide variety of background and foreground sound reinforcement applications utilizing 16Ω or 70/100V bypass configurations. The AcousticDesign™ Series are offering the integrators a premium quality installed sound solution where aesthetics, performance and consistent coverage are paramount. Designed especially for maintaining a consistent tonal characteristic across the entire family in pendant, ceiling and surface applications, the AcousticDesign Series are allowing the integrators seamless transitions within blended installations. The QSC AD-C4T is featuring a high quality 4.5" weather treated paper cone woofer with a .75" aluminum dome tweeter and 1" voice coil 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 150° conical DMT coverage. The accurate frequency response of the AD-C4T is maintained even in 70/100V applications by use of a low-loss, lowsaturation 30-watt transformer with selectable taps, including 16Ω bypass, using a rotary selector located under the snap-fit magnetically attached powder coat steel grille. Features Consistent tonal characteristics across the entire AcousticDesign™ family in both surface or ceiling applications DMT (Directivity Matched Transition™) waveguide ensures smooth, uniform frequency response over the coverage area Snap-fit magnetic grille 3x double stepped, long travel dog-ear blind mount system Advanced Intrinsic Correction™ voicings available via Q-SYS™ networked audio processing platforms, including CXD amplifiers Low-saturation and low-loss 70/100V transformers with 16Ω bypass Blemish-free removable logo Removable conduit cover plate, also available as accessory for pre-install wiring UL1480 and UL2043 certified EN54-24 Type A Available in black (RAL 9011) or white (RAL 9010) Complete EASE, CF2, CAD, & BIM information available online Specification SPECIFICATIONS AD-C4T Effective frequency range1 70 Hz – 20 kHz Rated noise power / voltage2 30 watts / 22 volts (rms) Sensitivity [dB]3 Sensitivity at 4m, 100V maximum tap 87.5TBD Rated coverage (-6 dB)4 150° conical DMT Directivity factor (Q)4 4.5 Directivity index (DI) [dB]4 6.5 Maximum continuous SPL [dB]5 102 Maximum peak SPL [dB]5 108 Nominal impedance [ohms] 16 Recommended amplifier 60 watts Transformer taps / impedance 16Ω (in bypass setting) 3.75W (70V); 7.5W (100V) Tap: 1333Ω 7.5W (70V); 15W (100V) Tap: 667Ω 15W (70V); 30W (100V) Tap: 333Ω 30W (70V); N/A (100V) Tap: 167Ω LF transducer 114 mm [4.5-inch] weather resistant paper cone woofer HF transducer 19 mm [0.75-inch] aluminum dome tweeter Input connector type Euroblock connector with parallel output Enclosure material ABS baffle on powder coated steel back can Grille material Powder coated steel Ingress protection IP-34 Operating environment Designed for indoor use Operating temperature range -20 to 50° C [-4 to 122° F] Cutout dimension Ø 195 mm [Ø 7.68-inch] Net weight 2.9 kg [6.4 lb] Product dimensions (Diameter x Height) Ø 230 x 176 mm [Ø 9.06 x 6.93-inch] Shipping weight 9.3 kg [20.5 lb] (pair packed) Shipping dimensions (H x W x D) 279 x 711 x 318 mm [11 x 28 x 12.5-inch] (pair packed) Included accessories C-ring and tile rails, rail screws, euroblock connector, cut-out template, grille Optional accessories AD-MR4 (pre-install mud ring) AD-CC4 (pre-install conduit cover) Safety Agency EN54-24: 2008 type A (No. pending) UL1480, UL2043, NFPA90, NFPA70 suitable for use in air handling spaces.
