AcousticDesign Ceiling Mount

AcousticDesign™ ceiling loudspeakers offer a variety of models specifically tailored for demands of higher fidelity applications.  Designed for clarity and presence, these blind mount loudspeaker systems deliver pristine audio reproduction for installations requiring a refined audio experience. 

Featuring an unusually wide frequency range and the ability to deliver higher SPLs, the AcousticDesign Series loudspeakers provide natural sounding lows and transparent highs for a truly musical sound with very low distortion. Coupled with wide and even dispersion, the AD-CI52T delivers outstanding coverage. 

As one of the most popular AD-C Series ceiling speakers, the AD-Ci52T employs a 5.25" weather-resistant LF transducer incorporating a low-distortion fiberglass cone, a 25 mm voice coil, and a rubber surround. The HF driver is a 1" pure titanium dome tweeter utilizing a neodymium magnet structure. 

The AD-Ci52T is a fully sealed speaker system. 

The AcousticDesign ceiling speakers are packaged with the backcan, support bracket, tile rails, and a grille. For integration with any décor, the trim and grille can be painted. Additionally, these speakers are well suited for use in air handling spaces per UL2043 and UL1480. They also feature a seismic tab for secondary support.

The following back boxes, grilles, and brackets are available for our AcousticDesign ceiling speakers:

         • AD-C1200: Back Box AD-C1200BB; Square Grille AD-C1200SG
         • AD-C820/C821: Back Box AD-C800BB (AD-C820 only); Square Grille AD-C800SG; Round Grille AD-C800RG
         • AD-Ci52T: Mud Ring Brackets ADC-MR and ADC-MRS (shallow) New Construction Brackets ADC-NC, ADC-NCS (shallow)
