Hertz Cento PRO CPK 690 - 6"x9" 360 Watt 2 Way Component Speakers with Tweeters

Like the other speakers of the Cento PRO line, the woofer cone is made of pressed paper, the most suitable material to obtain a linear and controlled emission even when the woofer is driven with very high power.

All electroacoustic parameters have been optimised to obtain maximum performance with door installations; we therefore find a magnetic group and voice coil improved for an excellent power handling and a lower resonance frequency.

The large emission area of the CP 690 increases the woofer efficiency and extends the response down to 35 Hz.

The crossover made with selected components, features a low-pass filter on the woofer with a 6 dB/oct. slope and

12 dB/oct. on the tweeter with three levels of attenuation.

CPK 690 is dedicated to the young enthusiast who wants a front row seat at their favourite concert while sitting comfortably behind the steering wheel.

Tweeters

• Soft Tetolon® fibre 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.

• “Centre Tuning Duct” geometry, for a lower resonance frequency and reduced harmonic distortion.
• Neodymium magnet with high-density magnetic flux, optimised 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 optimised with FEM (Finite Element Modelling) technique for a linear frequency response in off-axis installations.
• Wide range of accessories, for easy integration in OEM placements.

Woofer

• Pressed-paper cone with FEM-optimised geometry, it combines rigidity and lightness for a colour-free sound.
• 30 mm (1.2 in.) double layer voice coil sized to maximise high 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.

Crossovers

• Tweeter level adjustable via a three-position switch (-2, 0, +2 dB) for an optimal tonal balance that can be customised 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.
