Hertz MLK 1650.3 A component 2-way speakers

The Hertz MLK 1650.3 Legend speaker system is a two-way set designed for audiophile purists, the goal of which is to achieve maximum uniformity of sound color combined with very high dynamics and an extremely extended frequency response. This component system is designed exclusively for active connection and consists of tweeters and mid-bass speakers of the highest model line Mille Legend. The Hertz ML 280.3 Legend tweeters have a dome with a diameter of 28 mm, which is made of Tetolon® fibers. It is a mix of cotton and silk, which after impregnation with natural resin stands out with a very natural and uncolored sound with a minimum of resonance. The ratio of the diameter of the dome, its height and the profile of the surround ensures a very low Fs, a wide spread in the low frequency band and very low distortion. The ML 1650.3 Legend is equipped with a 36mm moving voice coil to ensure exceptional performance and very high thermal stability even for compositions particularly rich in bass frequencies. This size provides the best compromise between power and high frequency response. The geometry of the diaphragm was the subject of in-depth studies and measurements, which led to the optimization of the V-cone® profile. This profile prevents the membrane from deforming during its operation, ensures its correct position and maximizes the production of sound pressure. Pressed pulp membrane with cotton fibers combining stiffness and lightness to achieve a wide frequency response and limited decay at high frequencies. The result is a component system for installations focused on top quality sound and at the same time very high performance.

The main features of the ML 280.3 Legend tweeters

Neodymium magnet optimized using finite element magnetic flux simulations for maximum control and fast response to transients.
Extremely pure copper shorting ring for excellent extension of very high frequencies.
Die-cast aluminum faceplate with a profile optimized using FEA simulations to improve frequency response and dispersion.
Tetolon fiber dome optimized using FEA simulations for lower distortion and better dispersion in the high frequency range.
Frame construction and rear load cell derived from a solid CNC machined aluminum block to ensure mechanically inert resonance response.
Rear chamber rated at Fs only 900 Hz: low Fs ensures wide extension in the low frequency range and low distortion also in the crossover section, which allows the cut-off frequency to be reduced.
High-density damping material under the hood, low-density absorption material in the rear chamber, ensuring smooth acoustic emission and high damping in the low frequency area.

The main features of the ML 1650.3 Legend mid-bass speakers

Neodymium magnet optimized using FEA simulations for true dynamics and maximum control.
CNC machined plates with very low carbon content for maximum magnetic permeability and low distortion at high outputs.
Aluminum coated pole for linear impedance modulation and low distortion.
36mm double-layer CCAW voice coil wound on a polyamide former for exceptional performance and compression-free reproduction even in the most demanding musical passages.
Exponential V-cone® with optimized geometry for maximum linearity and dispersion in the mid-frequency range.
"Boundary Free" IIR rubber surround, for better efficiency and wider mid-bass frequencies.
Pressed pulp membrane with cotton fibers, combining stiffness and lightness, to achieve a wide frequency response and limited decay at high frequencies.
Three-arm, acoustically very transparent anti-resonance basket made of aluminum alloy with built-in ventilation holes.
CNC machined elegant diamond cut basket edge with Hertz logo.
Factory-supplied die-cast aluminum grille with diamond-cut aluminum Hertz logo.

Speaker typeCoaxial speakers: Coaxial speakers are characterized by a so-called all-in-one design. The tweeter and mid-bass speaker are in one basket. The advantage is simpler assembly, but thanks to the connection or proximity of the bands in one speaker, the sound quality will usually be reduced. As a rule, in the middle of the mid-bass speaker, there is a tweeter whose voice coil works in the second air gap of the common magnetic circuit. The three-way coaxial speaker consists of a mid-bass speaker, a center speaker and a separate tweeter in the front on a special beam. Component Speakers: Component speakers are characterized by a division into individual frequency bands, treble + mid-bass + or. bass band. The individual speakers can be placed completely separately, which results in a better sound and acoustic performance. In the vast majority of cases of component speakers, an external crossover is also supplied, which divides the treble, middle / mid-bass, and into the three-band the bass band or allows setting the decibel level of the tweeter (e.g. +2 dB, 0 dB, -2 dB), steepness (e.g. 6dB/Oct. 12dB/Oct.) or active or bi-amp connection.	Component 2 band
RMS powerRMS speaker power is the constant power of the entire system, not just one speaker or one side. This is also the performance of continuous use of the speakers. If the RMS power is exceeded for a long time, the speakers may be irreversibly damaged!	150 W
Max. (maximum performancePeak performance , which the speaker can play for a moment (approx. 0.5 s), for example when hitting drums in a song. If the max power is exceeded, the speakers will usually be damaged!	300 W
Sensitivity (SPL 2.83V/1m)Sensitivity, sensitivity or efficiency of the speaker. Speaker sensitivity is given in decibels (dB) and simply put, the higher the value, the lower the demands on the amplifier's power. This is a defacto rating of how a speaker converts watts to sound. Sensitivity ratings are in noise level measured at 1 meter from the speaker using 1 W (watt of power) or using 2.83 volts at the source at 1 meter. A higher decibel level means the speaker is louder with less power. For every 3 dB increase in sensitivity, the speaker requires half the power to reproduce the same volume. For example, if an 88 dB speaker needs 100 Watts to produce a certain volume, then a speaker with a sensitivity of 91 dB needs only 50 Watts to reach the same volume.	92 dB
ImpedanceImpedance - measurement of electrical resistance. When buying speakers, it is important to make sure that the impedance matches the amplifier or car stereo you are using. Example: A 2 Ohm speaker cannot be connected to an amplifier that is only stable up to 4 Ohms! A 4 Ohm speaker can easily be used with an amplifier that is stable up to 2 Ohms. The most common speaker impedance today is 3 - 4 Ohm.	4 Ω
Frequency rangeThe ability of the speakers to play a signal from the lowest frequency to the highest, or the speaker's ability to faithfully reproduce sound in a specific frequency band. Professionally: In the frequency range from 40 to 16,000 Hz, the vast majority of fundamental and overtones (harmonics) of all musical instruments are found. We are interested in the course of the radiated sound pressure in this range of frequencies when the loudspeaker system is supplied with constant power. We call this course the frequency characteristic, which tells us the level of radiated sound pressure in decibels (dB) depending on the frequency. The frequency characteristic of a speaker or speaker system can be expressed most succinctly with a graph. Mostly, however, the frequency characteristic is indicated by indicating the maximum tolerance of the sound pressure in the given frequency range, e.g. 50 to 15,000 Hz -+ 6 dB. Since the frequency characteristics of loudspeakers and systems in general are quite uneven, some manufacturers do not even specify this maximum tolerance of sound pressure in decibels in their catalogs for reasons of prestige. Data impoverished in this way is unfortunately worthless. What is valid is that the manufacturer offers a speaker system with a frequency range of 30 to 20,000 Hz, if he is worried about stating the maximum unevenness of the sound pressure in this range, because he can have a tolerance of, for example, +- 20 dB. The unevenness or undulation of the frequency curve in good speaker systems for high-quality music performance should not exceed +-3 dB in the 80 to 12,000 Hz band and +-6 dB in the 40 to 16,000 Hz band. Greater unevenness already depletes or emphasizes certain tonal areas, which can cause audible or even disturbing distortion. The proportion between fundamental tones and higher harmonics also changes, thereby changing the color of the sound, and individual musical instruments as well as the entire musical image sound unnatural.	40 - 28000 Hz
The diameter of the mid-bass speakerWe state the diameter of the speaker as the diameter of the entire speaker, not including the mounts, when smaller speakers (87, 100, 130 mm) have extra mounts. Some speakers are oval and there the dimension is given in inches, always the shortest side to the longest side. One inch is approx. 2.5 cm.	165 mm
Mid-woofer diaphragm materialThe material that was used for the speaker diaphragm. Don't be afraid of the paper, it surprisingly has a very natural and high-quality sound and, thanks to the surface treatment, it can withstand moisture without any problems.	Pressed pulp with cotton fibers
Overall tweeter diameterThe total diameter of the tweeter is given as the diameter of the individual tweeter without the installation houses.	35 mm
Tweeter dome diameterThe net diameter of the dome (diaphragm) of the tweeter.	28 mm
Tweeter dome materialThe shell material that was used in the manufacture of the tweeter.	Tetolone
Frequency crossover included in the packageThe crossover is an important part of defacto all loudspeakers. A crossover usually contains different resistor values, coil sizes, and capacitor types that fundamentally modify the sound. We describe below what the turnouts are for. Component Speakers: A crossover is part of every quality component speaker system. Its task is to ensure the distribution of frequencies that the amplifier produces in the entire acoustic spectrum of frequencies so that each of the speakers receives only that part of the band that it can optimally play in terms of efficiency and minimal distortion. Coaxial speakers: In most cases, coaxial loudspeakers have a simple crossover (6dB/Oct.) formed by a capacitor at the tweeter.	No
Cover grids included in the packageOriginal cover grilles in speaker packaging.	Yes
