Technical integration of voice coil and magnet for Hertz Cento Pro CPK 690

The Cento Pro CPK 690 from Hertz integrates a 30.5 mm voice coil for the woofer and a 25 mm voice coil for the tweeter, each optimally matched to the elliptical dimensions of the speaker. With a powerful neodymium magnet, the combination of voice coil and magnet ensures maximum control and minimizes distortion, even at extremely high volumes. The benefit of these features? Clear and controlled music reproduction, which is often compromised by distortion in competing products. Larger voice coils could theoretically offer even greater power handling, but at the expense of efficiency and finely tuned sound.

Pressed paper cone and FEM optimization: criteria for the perfect sound

The CPK 690's diaphragm is made of high-quality, pressed paper. Its FEM-optimized geometry ensures a perfect combination of stiffness and lightness, essential for undistorted sound reproduction. The choice of paper as the material prevents unwanted coloration in the sound image that could occur with heavier or stiffer materials. The diaphragm's behavior is particularly linear in the frequency range from 35 Hz to 22.5 kHz, resulting in a natural sound with impressive detail. While alternative materials could provide additional stiffness, they could compromise the liveliness and naturalness of the sound.

The technical finesse of Hertz Cento Pro CPK 690 Crossover

The CPK 690's 2-way crossover features an innovative crossover frequency of 6 dB/octave for the woofer and 12 dB/octave for the tweeter. This design provides optimal conditions for perfect soundstage in the car by harmoniously dividing the frequency response and clearly highlighting details. This results in clear, transparent music reproduction with a treble level that is adjustable in three positions (-2, 0, +2 dB). Combined with the 160 V capacitors with low internal resistance and pure copper for the coils, this results in maximum transparency, producing crystal-clear sound in the high-frequency range.

The relevance of the Thiele-Small parameters for Hertz Cento Pro CPK 690

The Thiele-Small parameters of the CPK 690 are precisely tuned: A Vas of 22.80 l ensures a deeper bass foundation, while a Qts of 0.48, a Qms of 2.2, and a Qes of 0.62 offer a balanced ratio of mechanical and electrical quality. These parameters support the sonic performance in both sealed and ported cabinets. An Mms of 25.3 g and a BL factor of 6.9 T*m provide an indication of the speaker's efficiency and power. Higher values, for example, would often result in a loss of fine detail and dynamics, especially since lighter membranes offer greater agility in comparison.

Genuine innovation with the Center Tuning Duct technology

Hertz's Center Tuning Duct technology is specifically tailored to the CPK 690. This geometry allows for a lower resonant frequency and reduces harmonic distortion. These distortions are improved by modulating the airflow within the speaker, resulting in clean and precise music reproduction, even at high volumes. Without this technology, the resonant frequency would be more likely to compromise sound clarity or cause distortion during playback.

Dimensions and weight: Relevance for the installation of the CPK 690

The Cento Pro CPK 690's 6x9 dimensions combine space-saving dimensions with impressive acoustic dynamics. The woofer weighs 1.69 kg, while the tweeter weighs just 0.07 kg and the crossover weighs 0.2 kg, making them ideal for space-constrained installations. These dimensions reduce installation effort and offer a wide range of options for different automotive environments.

Installation accessories for Hertz Cento Pro CPK 690: Practical advantages and flexibility

The extensive range of accessories allows for easy, flexible installation in your car's original installation locations. The compact 3-spoke basket with rubber protection not only optimizes space but also minimizes vibrations. These rubber elements significantly dampen unnecessary vibrations caused by vehicle operation. This sophisticated design reduces the risk of installation problems while simultaneously increasing the car's acoustic efficiency.

Flexibility and user experience with adjustable treble level

With its adjustable high-frequency level, the Cento Pro CPK 690 offers a user experience that appeals to both advanced and new users. Being able to adjust the dB level yourself gives you the opportunity to tailor the sound profile of your audio device to your exact personal preferences. A higher contribution of high frequencies can increase the soundstage width, while a more restrained setting supports you with more clarity in the mids and bass.
