Audison APX 4 is a Prima Series 4" (100mm) 2-way coaxial loudspeaker engineered for OEM-integration sound quality upgrades in vehicles that utilize compact 4" speaker locations. The APX 4 delivers improved vocal clarity, midrange articulation, and smooth high-frequency response over factory premium audio systems without requiring fabrication or DSP crossovers. The coaxial geometry maintains coherent phase behavior and wide dispersion in door, dash, or rear panel locations where small-format speakers are commonly used. Efficient motor and suspension design allow the APX 4 to perform on factory head units while scaling with external amplification and DSP for higher performance OEM+ builds.
