4.5-inch Coaxial Two-Way Surface Mount
Surface Mount Loudspeakers

The CS4 incorporates the same 4.5-inch full-range loudspeaker (as the C4) in a black or white paintable ABS surface mount enclosure. It also 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 CS4 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.

Easily outperforming loudspeakers of a larger size format, the CS4 provides high power handling, high sensitivity and realistic sound reproduction. This loudspeaker is equipped with a built-in autoformer, allowing large numbers of distributed loudspeakers to be powered from a 70V or 100V amplifier output. A convenient front-accessible power tap switch is hidden behind a rotatable logo. Installation is simple and flexible using the included multi-angle pan-tilt bracket which allows low profile mounting and precise positioning of the enclosure in either horizontal or vertical orientation.

Thanks to the internally reinforced enclosures, zinc-rich epoxy dual-layer powder-coated grilles and brackets, weather-treated drivers, and the included IP56 sealed wiring cover, all standard surface mount models are equally suited for indoor or outdoor direct exposure applications.
