Audison
AP4AP4 100 mm Midrange Speakers
Very extended frequency response, in both high and low frequencies, combined with high efficiency. No passive crossover required to maximize efficiency: the cone is optimized with the Klippel Scan Vibrometer to obtain a calibrated mechanical low-pass cut-off frequency.
Highlights
- Very extended frequency response, in both high and low frequencies, combined with high efficiency.
- No passive crossover required to maximize efficiency: the cone is optimized with the Klippel Scan Vibrometer to obtain a calibrated mechanical low-pass cut-off frequency.
- Water-repellent treated paper cone, featuring a profile developed with FEM (Finite Element Method) simulation technology and optimized with the Klippel R&D Scan Vibrometer.
- Reduced mounting depth, providing ease of installation in OEM placements.
