ESB Audio 4.100 speakers

ESB Audio speakers series 4000

The latest model range 4000 (Quattromila), introduced in 2024, benefits from extensive technical research that enabled the use of new materials previously reserved only for much more expensive speakers. This was achieved also through parallel development with the top 9000 (Novemila) series, with which the Quattromila series shares several common elements. ESB's engineers aimed to create a significantly cheaper product while maintaining high-quality sound and exclusive design. The design is striking at first glance, led by luxury grilles on all speakers with a matte black finish, expressing an aesthetic similarity to the top model range. All speakers in the Quattromila series also feature powerful neodymium magnets that ensure above-standard efficiency and the ability to reach high acoustic pressure levels even with low-power amplifiers. Other noble materials such as aluminum or steel are also used, but the main advantage of the Quattromila speakers is above all the sound. The sound can be defined as "classic", in other words genre-neutral and without coloration. This significantly differentiates it from the higher 5000 series, which is almost competitive in price and whose sound is more suitable for so-called "light music" (often described as easy-listening music), but also for jazz or rock. Emphasis was also placed on easy installation in today’s modern vehicles - all speakers have high sensitivity, are designed for off-axis sound reproduction, and for example the tweeters offer a choice of three design installation variants. The 4000 series includes a total of five individual components for variable assembly of two-way and three-way systems, which, thanks to their sound quality, will impress even very demanding listeners.

ESB 4.100 center speakers

The center speakers of the 4000 series underwent a long and very costly development process to achieve highly faithful sound with an extended frequency response. The speaker features a high-quality neodymium magnet (Y-35), which guarantees surplus energy and easily reproducible excursion peaks during which the voice coil operates very quietly in the magnetic field. The pole plate, made of extremely low-carbon steel, is cold-forged from a single piece and machined on a CNC using FEM technology, achieving perfect geometry. This creates an additional concentration of magnetic force right in front of the voice coil, focusing the magnetic flux where it is needed. This type of manufacturing process ensures perfect flatness so that the plate sits in the same plane as the magnet without reducing the crucial magnetic flux. The speaker basket is made from pressure-cast aluminum alloy. This construction offers perfect stiffness and minimal resistance to airflow movement without changing sound quality. The casting of this aluminum basket follows strict procedures that ensure compliance with regulatory specifications and help maintain consistent casting quality. The aluminum voice coil with a copper cladding can handle very high power while reproducing music with extreme realism and high dynamics. The voice coil made of copper-clad aluminum wire is very light and offers excellent heat dissipation. At the same time it provides maximum sensitivity and extends the speaker's high-frequency response. The cone made of long-fiber pulp with a special outer treatment represents a perfect combination of lightness, stiffness and internal damping. The surround made of soft nitrile rubber is UV-resistant and unaffected by temperature changes, ensuring that the speaker's excellent acoustic properties are maintained over time. The special surround design ensures perfect and free forward and backward movement. The package includes luxury steel grilles with a matte black finish. 

About ESB Audio

The history of ESB Audio goes back to 1972 when this Italian brand was officially founded. ESB Audio is among the most famous loudspeaker manufacturers of the second half of the 20th century and during its rich history they launched many innovative technologies and numerous high-end home audio products that achieved huge worldwide success. Building on this experience, ESB engineers began research in 1984 focused on optimizing sound for the automotive environment and two years later started producing their first car speakers. Due to great success, ESB increasingly focused on the automotive industry and its demanding challenges. Car audio became a phenomenon of the time and in 2005 a school dedicated exclusively to vehicle sound systems was founded in Aprilia, where ESB is based. At that time the decision was made to leave the world of home audio and focus exclusively on vehicle sound systems. Today ESB, together with the American manufacturer of audiophile amplifiers and DSP processors Zapco, is part of the Italian-Apex Group. The range includes several model lines headed by the high-end three-way system Novemila, which represents some of the most acoustically and aesthetically advanced speakers on the market today. This is also ESB Audio's main mission: to manufacture speakers of the highest quality focused on faithful sound, allowing the user to hear reproduction as the performer intended. Exactly according to the company slogan "Just like live".
