QSC AD-C152ST

The QSC AD-CI52ST-WH Design "C" Series ceiling speakers employ a 5.25" weather-resistant LF transducer incorporating a low distortion fiberglass cone, a 25mm voice coil, and a rubber surround. The HF driver is a 1" pure titanium dome tweeter utilizing a neodymium magnet structure. With its larger, ported enclosure, the AD-CI52ST provides greater low frequency extension and makes an excellent choice for installations requiring shallow install depth - such as cruise ships. By contrast, the AD-CI52T has a smaller "footprint" - enabling this speaker to be less visually intrusive. While both models are weather-resistant, the AD-CI52T, by not being a ported enclosure, carries the added benefit of being 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. There is also a seismic tab provided for secondary support.

Delivering exceptional sound quality and value for background music and paging systems, the AD-CI52T and ADCI52ST are ideal for a wide range of business applications, including hotels, restaurants and pubs, corporate offices, retail spaces, convention centers, recreation facilities, churches, airports, etc. 

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 and AD-CI52ST deliver outstanding coverage.
