Hertz Cento Pro Series at 4 Ohm 2-Way Component Speaker System - CPK690-P

Features

CP 25: 

• Soft Tetolon® fiber 29 mm (1.14 in.) dome and 25 mm (1 in.) voice coil cooled with ferrofluid, for a natural and yet detailed reproduction of musical nuances.
• “Center Tuning Duct” geometry, for a lower resonance frequency and reduced harmonic distortion.
• Neodymium magnet with high-density magnetic flux, optimized for maximum control during high-energy dynamic transients in the mid-high frequency range.
• Rear chamber filled with damping material selected and sized for low resonance, ensuring a natural medium range and low crossover frequency with the woofer.
• Faceplate geometry optimized with FEM (Finite Element Modeling) technique for a linear frequency response in off-axis installations.
• Wide range of accessories, for easy integration in OEM placements.

CP 690: 

• Pressed-paper cone with FEM-optimized geometry, it combines rigidity and lightness for a color-free sound.
• 30 mm (1.2 in.) double layer voice coil sized to maximize fhigh excursion and power handling.
• High-density flux ferrite magnet combined with low-carbon polar plates for reduced distortion at high power levels.
• Compact and transparent three-spoke basket, acoustically combined with a rubber magnet cover for total damping of spurious vibrations.

CPCX 690: 

• Tweeter level adjustable via a three-position switch (-2, 0, +2 dB) for an optimal tonal balance that can be customized by the user
• Crossover frequency at 3.1 kHz, with a 12 dB/Oct. and 6dB slope for the woofer, which enhances the reconstruction of the virtual stage in the car compartment.
• 160 V metallic finish capacitors with high quality polyester film featuring an ultra low DF value and low resistance pure copper inductances, for maximum sound transparency and clear high frequencies.
• Compact design with metallic finish to the benefit of the ease of installation, with air vents for efficient heat dissipation.
