FEATURES
- CP 25:
-
29 mm (1.14 in.) Soft Tetolon® cone and 25 mm (1 in.) voice coil cooled with ferrofluid, for a natural and detailed reproduction of music with the finest nuances.
-
"Center Tuning Duct" geometry, for a low resonance frequency and reduced harmonic distortion.
-
Extremely strong neodymium magnet, optimized for maximum control at high loads in the high-mid range.
-
The rear chamber is filled with damping material for a low resonance frequency and low coupling to the bass-midrange driver.
-
Faceplate geometry optimized with FEM (Finite Element Modeling) technique for a linear frequency resonance in off-axis installations.
-
Wide range of accessories for easy installation in original mounting positions.
-
Pressed paper diaphragm with FEM-optimized geometry combines rigidity and lightness for a discolouration-free sound.
- 30 mm (1.2 in.) dual layer voice coil designed for maximum excursion and maximum power handling.
-
Extremely strong neodymium magnet combined with low-carbon pole plates to reduce distortion at high volumes.
-
Compact 3-spoke basket that acoustically dampens vibrations in combination with a rubber protection for the magnet.
-
Tweeter level adjustable in three positions (-2, 0, +2 dB) for an optimum tonal balance that the listener can set himself.
-
The crossover frequency for the tweeter is 3.1 kHz with a slope of 12 dB/oct. and there is a slope of 6 dB/oct. for the bass-midrange driver. This ensures good stage imaging in the car.
-
160 V capacitors with a low internal resistance and pure copper coils ensure maximum transparency in the high frequencies.
-
Compact design with a metallic look for easy installation, with ventilation slots for efficient heat dissipation.
