ESB Audio Audi A4 Front 200 Speakers
More about the product
2-way component speakers ESB Audio Audi A4 Front 200 (year of manufacture 2008 - 2015)
The first special speakers for specific car models from ESB were made for Audi cars. The ESB team sought a solution to reconcile the specific shape and characteristics of the Audio speakers and the original amplifier with too little power to drive high-quality speakers. In these cars, it is not possible to replace the amplifier integrated in the car's electronic system, even thanks to its own MOST optical cabling and factory DSP. So it was a big challenge to develop significantly better quality speakers with the same or higher efficiency as the originals and that would match perfectly with the factory amplifier. The shape of the speakers and their mounting depth are also very specific. This is limited to only a few centimeters, so it was not possible to use classical diaphragms with traditional voice coils and a group of magnets. However, it has been possible to develop top-of-the-range ESB loudspeakers in sizes 200 and 165 mm with highly efficient and small-sized neodymium magnets and a special voice coil. The speakers have a low depth and can be adapted exactly to the car space with the help of special car adapters in the elegant Ferrari red color. Also the connectors match the factory ones for very easy installation in the spirit of plug & play. Like all ESB speakers, this set for BMW presents a high-quality sound that will satisfy even the most demanding clients. In the ESB product portfolio, these loudspeakers belong to the 6000 model series, which means they belong to the hi-end area. So you can count on very advanced sound and processing. This set is intended for the front doors of the Audi A4 manufactured in 2008 - 2015. Rear speakers are also available.
Tweeters A4-FTW1
The set includes tweeters with a diameter of 32 mm made of silk for a very soft and natural sound. The outer suspension is made of the same material, but is additionally covered with damping material to eliminate vibrations and resonances. The 32.5mm voice coil has an aluminum support and features excellent ventilation with anti-resonance chambers. High quality N-42 neodymium magnets are optimized through computer simulations to achieve better efficiency and improve linearity to provide more and better power management and increase bandwidth and efficiency. Of course, the same connector as the factory tweeter is used, and the high power of 80 W RMS is impressive.
Mid-bass speakers A4-F81
These speakers have the same shape, connector and especially the 200 mm dimension as the factory Audi speakers. However, the sound quality is completely different, and the power value of 120 W RMS is also more pronounced. The membrane is made of mineral-filled polypropylene, which excels in high mechanical rigidity, thermal stability and excellent dimensional stability in a wide temperature range. The diaphragm suspension is made of durable rubber for a long speaker life. Like the tweeter, this midrange driver uses a special and high-quality N-42 class neodymium magnet with computer simulation optimization for better efficiency and improved linearity to provide more and better power management and increase bandwidth and efficiency. The 32.5mm voice coil has an aluminum support and features excellent ventilation with anti-resonance chambers.About the ESB Audio brand
The history of ESB Audio dates back to 1972, when this Italian brand was officially founded. ESB audio is one of the most famous speaker system manufacturers of the second half of the 19th century, and during their rich history they have launched many innovative technologies and many high-end home audio products that have achieved huge worldwide success. Based on the experience gained, in 1984, ESB engineers began to engage in research aimed at optimizing sound in the automotive environment, and two years later they started the production of the first car speakers. Thanks to the great success, ESB began to focus more and more on the automotive industry and its demanding challenges. Car audio is starting to be a phenomenon of the time, and in 2005 a school focused exclusively on vehicle sound was founded in the city of Aprilia, where ESB is based. It was then that the final decision was made to leave the world of home audio and focus exclusively on vehicle sound systems. Currently, ESB belongs to the Italian company Apex Group together with the American manufacturer of audiophile amplifiers and DSP processors Zapco. In the offer you will find several model lines of speakers, led by the super high-end Diecimila three-way system, which represents probably the best quality and most expensive car speakers on the market today. And that is the main mission of ESB audio. To produce speakers of the highest quality, focused on faithful sound, which will allow the user to reproduce as the interpreter intended. Exactly according to the company's slogan "Just like live".

| 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. | Komponentní 2pásmové |
| 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! | 120 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! | 240 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. | 88,5 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 - 25000 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. | 200 mm |
| Installation depth of the mid-bass speakerThe installation depth of the speaker is measured from the bottom edge of the magnet to the bottom edge of the tin, plastic or cast speaker basket, or speaker bearing surfaces. | 26 mm |
| Overall tweeter diameterThe total diameter of the tweeter is given as the diameter of the individual tweeter without the installation houses. | 25 mm |
| Tweeter dome materialThe shell material that was used in the manufacture of the tweeter. | Hedvábí |
| 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. | Ne |
