Community C4LP 4.5" 2-Way, Full Range Low Profile Ceiling Loudspeaker

The C SERIES C4LP provides high quality paging and musical performance. Uniform voicing throughout the C SERIES means that the C4LP can be combined with the larger models of the Commercial Design product family 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. Exclusive Drop-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.
