Audison APX 5FeaturesConcentric Coaxial Tweeter: tweeter is mounted within the woofer with one single point of emission providing consistent phase response, with an accurate recreation of the sound stage comparable to that of a component system.Tweeter features an acoustic lens specifically designed to ensure an extremely linear frequency response, even in off-axis placement, typical of in-door installations.32 mm pure copper voice coil, for high power handling and outstanding low frequency controlOverall mounting depth optimized for OEM Integration thanks to the concentric tweeter and the low profile basketWater-repellent treated paper cone, featuring a profile developed with FEM (Finite Element Method) simulation technology and optimized with the Klippel Scan Vibrometer.TPU (Thermoplastic Polyurethane) surround, featuring the exclusive shallow “Triple Wave” profile, for maximum excursion linearity.Compact basket, protected by abrasion-resistant and scratch- proof coating, the motor affixed with damping epoxy adhesive.SpecificationsComponent: 2-way CoaxialSize mm (in.): Woofer; 130 (5), Tweeter; 24 (0.9)Power Handling: Peak; 150W, Continuous (RMS); 50WImpedance: 4 OhmFrequency Response: 70Hz - 23kHzMagnet size: mm (in.) 85 x 40 x 13; (3.35 x 1.57 x 0.51)Weight of one speaker: kg (lb); 0.74 (1.63)Woofer Voice Coil Ø: mm (in.) 32 (1.26)Tweeter Voice Coil Ø: mm (in.) 15 (0.6)ELECTRO-ACOUSTIC PARAMETERSD: 107mmXmax: ±2mmRe: 3.1ΩFs: 90HzLe: 0.07mHVas: 3.8LMms: 8.2gCms: 0.33mm/NBL: 4.6TmQts: 0.7Qes: .75Qms: 10.6Spl: 93dB
