AcousticDesign CI52T & CI52ST

QSC's AcousticDesign "C" Series represents the state-of-the-art for in-ceiling speakers. 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.

The AcousticDesign "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.

FEATURES

Wide-Bandwidth, High-Fidelity Performance - ensures a full, rich, musical sound with low distortion.
Shares Driver Technology with AD-S (surface mount) loudspeakers for Seamless Sonic Integration - provides the ability to mix speaker models within zones for the best possible coverage.
AD-CI52ST Employs Shallow Can - can be mounted in ceilings and standard architectural walls.
True High-Fidelity, 2-Way Design - speakers feature a 1" titanium HF dome tweeter for exceptional sound quality from a ceiling format loudspeaker.

SOFTWARE

EASE Address
EASE Address is a software that allows the modeling of acoustic sources, in particular distributed loudspeaker systems, in two dimensions. It allows the system designer to quickly develop a simple design for a ceiling loudspeaker system, while also allowing the easy and quick prediction of the system performance in a given hall.
