ESB Audio 4.6C speakers

ESB Audio 4000 series speakers

The latest model series 4000 (Quattromila), born in 2024, benefits from extensive technical research that has enabled the use of new materials, previously reserved only for much more expensive loudspeakers. This was also achieved thanks to the parallel development with the highest model series 9000 (Novemila), with which the Quattromila series shares several common elements. The main goal of ESB engineers was to achieve a much cheaper product, while maintaining high quality sound and exclusive design. It is the design that catches the eye at first glance, led by the luxurious grills of all speakers in a matte black finish, which expresses the aesthetic similarity with the top model series. In all speakers of the Quattromila series, you will also notice powerful neodymium magnets, which guarantee superior efficiency and the ability to achieve high sound pressure levels even when using low-power amplifiers. The other noble materials used, such as aluminum or steel, also command respect, but the main advantage of Quattromila speakers is above all the sound. This can be defined as "classical", in other words, genre-neutral and without sound coloring. This fundamentally differentiates it from the higher 5000 series, which almost competes in price and whose sound, on the other hand, is more suitable for so-called "light music" (often referred to as music that is easy to listen to), but also jazz or rock. Emphasis was also placed on easy installation in today's modern vehicles - all speakers have high sensitivity, they are also designed for off-axis sound reproduction and, for example, with tweeters, you can choose between three installation design options. The 4000 series includes a total of five individual components for the variable construction of two-band and three-band systems, which, thanks to their sound quality, will impress even the most demanding listeners.

ESB 4.6C coaxial speakers

Coaxial loudspeakers of the Quattromila series are characterized by almost identical parameters and sound characteristics as the component system of this series, and thus rightfully occupy a position among the best quality coaxial loudspeakers on the current market. The speakers immediately impress with their robust design, which hints at the performance potential of these speakers. These are dominated by a high-quality magnet (Y-35) of oversized dimensions, which guarantees an excess of energy and easily reproducible excursion peaks, during which the coil works very quietly in the magnetic field. The ultra-low carbon steel pole plate is cold forged in one piece and CNC machined using FEM technology to achieve perfect geometry. This creates an additional concentration of magnetic force just before the voice coil, which concentrates the magnetic force where it is needed. This type of manufacturing process ensures perfect flatness so the board sits flush with the magnet without reducing the critical magnetic flux. The speaker basket is made of die-cast aluminum alloy. This construction offers perfect rigidity and minimal resistance to air flow movement without changing the sound quality. Casting of this aluminum basket follows strict procedures that ensure compliance with regulatory specifications and help maintain consistent casting quality. The robust copper-clad aluminum voice coil can handle very high performance while reproducing music with extreme realism and high dynamics. The copper clad aluminum wire voice coil is very light and with excellent heat dissipation. The membrane made of long-fiber pulp with a special external treatment represents the perfect combination of lightness, stiffness and internal damping. The peripheral suspension made of soft nitrile rubber is resistant to UV radiation and unaffected by temperature changes, thanks to which the excellent acoustic properties of this speaker are preserved for a long time. The special construction of the edges ensures perfect and free movement forward and backward. Part of the mid-bass is a 25 mm tweeter of the Quattromila series with a silk dome ensuring faithful presentation of high frequencies. Optional matte black steel speaker grilles are also available.

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 20th 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 began 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".
