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. 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.
The AcousticDesign "C" Series ceiling speakers employ 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. They 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.
