Description
The APX 4 from Audison is a 4" (10 cm) coaxial loudspeaker that offers a smooth phase response thanks to its concentric coaxial tweeter. Its acoustic lens ensures a linear frequency response, even when the speaker is placed off-center. With a 32 mm pure copper voice coil, it offers high power handling and excellent control of low frequencies. The optimized installation depth and the flat basket make it ideal for OEM integration. The water-repellent paper cone and the TPU suspension with "triple wave" profile ensure maximum linearity. A compact, protected basket and a high-current-resistant fast-acting terminal round off the sophisticated design. All components have been optimally developed with the KLIPPEL suite.
Features
