Speakers UP S4MB-SUR for Mercedes

Mercedes is certainly synonymous with quality and German precision. As for the audio systems, it's like any other car, not much emphasis is placed on it. If you don't have an S-Class with the optional Burmester 3D audio equipment, you won't be able to fully enjoy the sound in the Mercedes. However, for the owners of C, E, S and GLC cars, the Match brand offers hope for improvement. Premium vehicles deserve premium sound. Match Upgrade speaker systems now offer an alternative that opens up new horizons in sound. The UP S4MB-SUR center high-end loudspeaker system is an ideal complement to the UP C42MB, UP S4MB-CTR , UP X4MB-FRT and UP 7DSP amplifiers for perfectly distributed sound in the car interior.

Why is the product unique?

You do not have to modify, cut or otherwise adapt anything in the car. Or complicatedly connecting amplifiers to the original system and disrupting the electronics. Entire sets of speakers are precisely adapted to the replacement of the original ones, using the Plug & Play system. It couldn't be simpler! The speakers are more sensitive, have higher performance and, thanks to high-quality materials, also a completely different sound. Therefore, there is a huge difference even when connected to the original system. The intention of the German developers was to bring you the experience of a live concert in your car, and they succeeded 100% with these speakers.

Key properties

Optimized sound characteristics for Mercedes-Benz cars for impressive sound combined with significantly increased performance.
Exclusively developed baskets and special connectors for Mercedes-Benz cars for the easiest installation.
Perfectly combinable with other MATCH UPGRADE components, e.g. DSP amplifier.

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.

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!	60 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!	120 W
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.	89 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.	90 - 20000 Hz
Center speaker diameterThe diameter of the center speaker is given as the diameter of a round speaker, not including the mount, where the mounts protrude even more on smaller speakers.	100 mm
Mounting depth of the center speakerThe mounting depth of the center speaker is measured from the bottom edge of the magnet to the bottom edge of the tin, plastic or cast speaker basket.	35 mm
Center speaker diaphragm materialDiaphragm material that was used in the manufacture of the center speakers.	Coated paper membrane
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
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.	No
