Crescendo Revolution 1S2 Component Speakers

Meet the Crescendo Revolution 1S2, a component system with impressive sound quality, introducing you to the world of affordable sound quality. Revolution 1S2 surprises with balanced tonality and advanced sound reproduction, thanks to carefully selected materials and quality components, along with excellent craftsmanship. The Revolution 1S2 system includes a mid-bass speaker with a paper diaphragm ensuring faithful sound reproduction and well-defined low frequencies. The 28 mm silk dome tweeter allows for detailed high frequency reproduction with exemplary clarity. A custom-designed grille ensures optimal sound passage. The integrated aluminum chassis of the tweeter not only enhances the beautiful design but also ensures minimal distortion and vibrations. The advantages of the Revolution 1S2 system include high real sensitivity and optimally tuned performance, making it easy to connect the speakers even to factory systems. The package includes a high-quality crossover with adjustable tweeter level and designer screws for speaker installation.

Paper Mid-bass Diaphragm

The mid-bass speaker of the Revolution 1 basic series is equipped with a paper diaphragm with water-resistant treatment, allowing for fast and precise response to sound signals due to its low weight. This enables the diaphragm to reproduce faithful sound with very good dynamics and precise details. Paper also naturally dampens unwanted resonances, contributing to cleaner and more natural sound. The diaphragm includes a concave dust cap, which helps better direct sound dispersal, leading to more even sound distribution in the space. The concave shape also minimizes unwanted resonances that could negatively impact sound quality. This design also allows for a wider frequency response. The use of paper as a material provides lightness and flexibility, which is advantageous for quick response to sound signals.

Motor with Powerful Ferrite Magnet

The motor with overhung construction features a coil larger than the length of the magnetic gap in which the coil moves. This design allows the speaker to achieve more linear coil motion, leading to lower distortion and better sound quality, especially at higher volumes. The longer coil allows for better control over diaphragm movement. The motor with a robust ferrite magnet ensures high stability of the magnetic field and contributes to consistent and reliable mid-bass performance.

Silk Dome Tweeter

The silk dome tweeter with a diameter of 28 mm allows high-frequency reproduction with excellent clarity and outstanding detail. Silk is known for its smooth and natural sound, wide frequency response, and very low weight, contributing to high sensitivity and quick reaction to sound signals. The integrated aluminum chassis of the tweeter not only enhances its beautiful design but also ensures minimal distortion and vibrations, aided by a custom-designed aluminum grille for optimal sound passage. A powerful neodymium magnet ensures high magnetic performance, quick diaphragm response, optimal control, and low distortion. The silver-plated copper wire for tweeter connection contributes to sound clarity.

Two-Way Crossovers

The set includes two-way passive crossovers with quality components. The crossover effectively divides the sound signal between the tweeters and mid-bass speakers, ensuring a balanced and harmonious sound experience. A 12 dB per octave high-pass filter and a 6 dB per octave low-pass filter allow for clean and detailed high frequencies and smooth transitions in low frequencies, contributing to rich bass without distortion. The impedance compensation feature ensures a stable and balanced load for the amplifier, minimizing distortion and improving overall sound quality.

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-way
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!	75 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.	90 dB
Sensitivity (SPL 1W/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.	87 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.	60 - 20000 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 paper
Resonant frequency of the mid-bass speaker	49.8 Hz
Overall tweeter diameterThe total diameter of the tweeter is given as the diameter of the individual tweeter without the installation houses.	53.5 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.	Silk
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.	Yes
Options for setting the frequency crossoverThe unwritten rule is that the more expensive the speakers, the more options the crossover has for adjusting the sound. The most common way to adjust the crossover is attenuation on the tweeter. More advanced crossovers also offer the option of setting the steepness on the mid-bass and tweeter or adjusting the frequency range.	Yes
