Home | Products | C4


The C4 has a wider dispersion than the larger models. It contains a proprietary Tru-Phase™ waveguide that produces a consistently wide conical polar response up to 16 kHz. The C4 features a genuine coaxial design using separate magnets for the LF and HF drivers for reduced distortion and high sensitivity, thereby permitting up to 3 dB greater output level while requiring up to half the amplification power of competing products. The C SERIES ceiling loudspeakers are all ETL listed, and have similar sensitivity and output capabilities.
