Product Overview
The Community C4 Commercial Design Series ceiling speaker provides high quality paging and musical performance. Uniform voicing throughout the Commercial Design Series means that the C4 can be combined with other models of the Commercial Design Series without compromising consistency from zone to zone. Community’s proprietary Tru-Phase™ waveguide produces a consistently wide conical polar response up to 16 kHz. The genuine coaxial design uses separate magnets for the LF and HF drivers for reduced distortion and industry-leading sensitivity, thereby permitting up to 3 dB greater output level while requiring up to half the amplification power of competing products. ExclusiveDrop-Stop™ tabs allow single-handed placement to speed installation and reduce labor time. Drop-Stop’s spring-loaded legs support the back can so that the installer no longer needs to hold the can against the tile while tightening the clamps. The front-face wattage selector switch enables quick adjustment of 70V/100V tap levels. A variety of installation accessories are available to accommodate different ceiling materials.
