The Audison APX 5 is a 2-way coaxial speaker designed to fit into the factory locations of most vehicles, making it a practical choice for those looking to improve their car's original audio. It features a 130 mm woofer paired with a 24 mm tweeter in a concentric coaxial design, which uses an acoustic lens-diffuser to expand the radiation angle for mid and high frequencies. This layout helps the speaker approximate an ideal point source, ensuring that different frequency registers are phase-matched for a more cohesive sound. Built for durability and performance, the speaker uses a water-repellent pressed cellulose cone with an exponential profile and a 3-wave suspension to maintain linearity during maximum excursion. The internal components are supported by a high-density flux ferrite magnet and a compact basket protected by a coating that resists scratches, chips, and corrosion. With a continuous power rating of 50 W and a peak of 150 W, these 4 Ohm speakers deliver a frequency response from 70 Hz to 23 kHz with a sensitivity of 91 dB/Spl. Its shallow mounting depth of 48 mm allows it to slide into tight door panels without interference.
