Manuale  

Hertz CPK 165 is a two-way kit consisting of a pair of CP 165 woofers, a pair of CP 25 tweeters and a CPCX 2 crossover with a 12 dB / Oct cut.

The tweeters of the CPK 165 kit are made with a Tetolon dome and 25 mm coil, elements that give it a very extended and linear frequency response.

CP 25 woofers, for their part, benefit from the "Center Tuning Duct" technology: the tunnel at the center of the powerful Neodymium magnetic circuit, allows the exchange of low resistance air between the dome and the rear loading chamber, granting perfect perfection. 'acoustics. The result is a low resonance frequency, functional at the intersection with the woofer, to the advantage of the sound stage which remains wide in height.

The sophisticated design of the mobile group and suspensions of the CP 165 woofer, with a resonant frequency calibrated at 60 Hz, gives it a powerful medium-low with excellent punch, making listening to genres rich in low frequencies a unique experience.

The basket respects the Mille family-feeling with the addition of damping and protective rubber: the material of the cone derives from the Mille Pro, as well as the butyl rubber of the suspensions and the Tetolon fiber of the tweeter dome. These materials have excellent damping and lightness characteristics producing a balanced sound, free of resonance peaks.

The CPCX 2 crossover with 12 dB / Oct cut. uses hi-grade components such as air-wound chokes and 160v polyester capacitors. Allows three level adjustments for the tweeter (-2, 0, +2 dB) ensuring optimal and customizable tone balance, all in a compact case in

High resistance ABS with metallic finish.

Included in the package are the woofer grids made from a combination of metal mesh and high-strength ABS plastic frame. The combination of these two elements allows you to customize the installation with a refined and elegant design.

Characteristics of the components of the CPK 165 kit

CP 25 tweeter:
1. Soft dome in 29 mm tetolon fiber, for a natural and at the same time detailed reproduction of the musical nuances.
2. “Center Tuning Duct” geometry, for a lower resonance frequency and reduced harmonic distortion.
3. Neodymium magnet with high density magnetic flux, optimized for maximum control during high energy dynamic transients in the medium-high frequency range.
4. 25 mm mobile coil cooled with ferrofluid.
5. Rear chamber filled with selected damping material and sized for a low resonance, ensuring a natural mid range and a low crossover frequency with the woofer.
6. Faceplate geometry optimized with FEM (Finite Element Modeling) technique for linear frequency response in off-axis installations.
7. Wide range of accessories, for easy integration in preparation.

CP 165 woofer:
1. Pressed paper cone with geometry optimized with FEM technique, combines rigidity and lightness for a colorless sound.
2. High flux density ferrite magnet combined with low carbon polar plates for less distortion at high power levels.
3. 25mm diameter pure copper coil to guarantee high excursions.
4. 3-spoke basket, compact and transparent acoustically combined with a magnet cover in anti-vibration rubber for total damping of spurious vibrations.
5. Elegant grill with structure in high resistance ABS plastic with metallic finish combined with a protective metal mesh.

CPCX 2 crossovers:
1. Adjustment of the tweeter level by means of a three-position switch (-2, 0, +2 dB) for an optimal tonal balance that can be customized by the user.
2. 160 V metallized high quality polyester film capacitors with an ultra low DF value and low resistance pure copper inductances, for maximum sound transparency and clear high frequencies.
3. Compact design with metallic finish to the advantage of ease of installation, with air vents for efficient heat dissipation.
