Q-SYS AcousticDesign 4.5" Ceiling Speaker w/ Zero Bezel - Pair

About: Q-SYS AcousticDesign 4.5" Ceiling Speaker w/ Zero Bezel - Pair

The Q-SYS AcousticDesign AD-C4T-ZB is a 4.5” two-way, zero bezel 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-C4T-ZB features a high quality 4.5” 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 Q-SYS’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-ZB is maintained even in 70/100V applications by use of a low-loss, low-saturation 30-watt transformer

with selectable taps, including 16Ω bypass, using a rotary selector located under the 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 loosening 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 Platform including CX-Q Series amplifiers.

The AD-C4T-ZB is available in white and may be painted to match any decor.
