Overview Car component acoustic Hertz CK 165 and CK 165 L

A series of car acoustics Hertz Cento replaced the famous line of Hertz Energy 5 generations. Cento translated from Italian means "100". New dynamics have become a logical extension of the model range of automotive acoustics from the popular German brand Hertz. In particular, the component options CK 165 and CK 165 L replaced the speakers of Energy.5 series. It is there we consider in this article in more detail.

Overview of component car speakers Hertz CK 165 and CK 165 L

In the process of creating a new "cell" series speaker parameters were significantly improved. In particular, they have a new optimized with the most advanced software magnet system. In the end, the updated version has a design that will help to minimize distortion and improve linearity of the speakers sound.

In this article, we compare the two sets of CK 165 and CK 165 L in composition, functionality, sound, etc. They belong to the most popular sizes-165 mm. In this model CK 165-a standard version and CK 165 L different, they are similar, but there are some differences. Consider their features in more detail.

The main components

Hertz Cento CK 165 includes: a low-midrange C 165, C 26 and tweeter crossover ССХ2.

Hertz Cento CK 165 L comprises: a low-mid-range speaker 165 C L, C tweeter 26, two separate wire crossovers ССХ 2T and 2ССХ W.

Settings tweeter

tweeter CP 26 has a diameter of 44 mm, it is obtained from an innovative dome ultralight material tetolon and open design protective mesh, which allowed to significantly expand the frequency range of tweeter.

About Tetolon should be discussed separately, it is a special microporous polymer in the material combines high toughness of silk, and the stiffness of the polymer film, which ultimately provides a better and clear treble.

The suspension in the dynamics of a half-wave, is it possible to achieve excellent linearity. The voice coil has a diameter of 20 mm, for cooling, a special ferromagnetic liquid. As for the magnetic system, it is represented by a neodymium magnet.

Thanks to the special shape of the front sections and profile dome tweeter has a sufficiently smooth frequency response. Also, worth mentioning the relatively low resonance frequency index (about 1.5 kHz), which favorably affects the consistency of tweeter with a basic low-mid-range speakers when playing audio at lower frequencies. It is also beneficial to the height of the sound stage, which is available for installation of the speakers in the car.

Features Main speaker

C 165 left, right-C 165 L. You see the difference? At first glance, it seems that they do not exist, but in reality they are. It is enough to turn the speakers, and then to the naked eye, they become visible. The thing is that these models have a diffuser made of slightly different material.

For example, the model C 165 L is formed from a classical unpressed pulp, while the dynamics of the set C 165-of pressed pulp with the addition of special mica filler. When this dust cap V-cone both models polypropylene and has a concave shape.

From the diffuser material is directly dependent sound speakers. Using cellulose contributes to achieving an optimum balance of parameters such as weight, stiffness and the internal damping. However, due to the fact that the composition and processing of different material, and the sound of these two models is slightly different. Speakers C 165 L gives a good punch, even when listening to music at low and medium power. They allow you to enjoy the composition which has a very rich range of low frequencies.

If we talk about the differences, the C 165 L has an increased stroke of the diffuser, which contributes to better efficiency in the reproduction of low frequencies-this, just, and said suffix added to the name of L (Low-which means "low"). It is traditionally assigned to the speakers that have a diffuser of unpressed pulp.

The internal content and design of the speakers are identical, we consider it as an example C 165 L. acoustics Here there is a reliable ventilated magnet system with an additional hole in the center of the core. Ferrite magnet itself, it has a medium size. The construction is designed so that the resulting magnetic flux density high, and the use of low-carbon polar plate minimizes distortion during operation at high power. core shape allows to achieve the correct distribution of the magnetic field near the magnetic gap.

Shopping sturdy and compact, thanks to the connection with the rubber cap of the magnet is provided not only a good protection of internal components of the speaker, but also increases the damping rate (quenching distortion), which minimizes the probability of occurrence of parasitic oscillation. Since then mounted voice coil diameter of 25 mm made of aluminum with copper coil, it is better cooled, which is also beneficial to the quality of the sound.

As for size, both the speaker and the same both in terms of size, and for mounting dimensions: overall diameter of 165 mm and an installation diameter of 142 mm, installation depth-63 mm.

crossover

The set CK 165 used passive crossover CCX 2, it demonstrates the excellent work and good coordination with the speakers. It is made of high quality components. Dimensions of his modest 102h76,5h 32.5 mm. Due to the low frequency section 2.5 kHz and the presence of second order filters crossover allows obtaining a higher machine sound stage without distortion. The inductance of the low-pass filter received ferromagnetic core, it is possible to reduce the resistance. A high pass filter inductance "airbag." If desired permitted level control Tweeter (0/+ 3 dB).

With regard to the second set, then the CK 165 L crossovers separate, it makes them connect to standard wiring of the vehicle more comfortable. Frequency partition immediately above, it is up to 3.8 kHz. In CCX 2W set of first order low pass filter, and the CCX 2T-second-order high pass filter.

At the same time, both crossover have the same dimensions: 72x 23 mm 45,5h.

It is also worth mentioning the optional accessories. Both acoustic models are also equipped with special cups for mounting tweeters and protective mesh grills CG 165.

Features of sound component acoustics

The sound of these two options Car component speakers is quite realistic and clear. The difference, of course, there is, but it is insignificant. In the speaker CK 165 sound is sharper with a good bit, but at the CK 165 L notes come out juicier, but at the same time the sound of a light and airy, due to the fact that the lower-case overload capacity they are slightly higher than that of the first model. In general, the sound of these two options specific to some significant differences are not observed, more and more reduced to a small nuance. Both are good in their own way.

At the CK 165 index of nominal power of 95 W and a peak-285 watts. While a second set CK 165 has parameters L slightly higher: nominal capacity-100 W, peak-300 watts. The frequency characteristic is almost the same: 55-22500 Hz (at 165 CK) and 50-22500 Hz (CK at 165 L).

With regard to the working resistance, all the speakers have a nominal rate of 4 ohms. While allowing some variation in the range of 3.8 to 4.9 ohms. Speakers differ low self-inductance and a very good damping (Ferrofluid liquid plus acoustic)-all this allows you to get a smooth and clear sound without distortion and noise.

Although the resonance frequency of 1.5 kHz or higher, which also contributes to a very smooth and high-quality sound. Both speakers observed excellent sound good quality and purity of the free space.

The axial frequency response and both options fairly smooth, although when listening to a slight subsidence in the midrange. Angular characteristics they are also quite good, smooth frequency response position is maintained approximately the level of frequency of 2.5-3 kHz, then in decline. In general, the sound is very good, especially for the acoustics in this price range, with no sudden subsidence, vibrations and distortion.

Summing up

Both sets are very similar in design and packaging, the only difference in the crossover and the material used in the bass/midrange speaker cone. Acoustics Both models demonstrates traditional products for Hertz vigorous and realistic sound. To Say which option is better, it is difficult, because here everything is very individual. From the sound of the difference is, but it is not critical, since everyone has their own preferences.

Unconditionally it can be argued that the car speakers Hertz CK 165 and CK 165 L-is high quality modern dynamics, reliable and with good sound at an affordable price.
