Features
- 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.
- TPU (Thermoplastic Polyurethane) surround, featuring the exclusive shallow “Triple Wave” profile, for maximum excursion linearity.
- 25 mm pure copper voice coil; ensuring precise balance in the mid-high frequency range.
- Compact basket, protected by abrasion-resistant and scratch-proof coating.
- Developed with the KLIPPEL suite.
