ESB Audio 9.1T-28 speakers

ESB Audio 9000 series speakers

The ESB 9000 series speakers (Novemila) proudly belong to the high-end segment and belong to the most technologically advanced car speakers ever made. And also to the most elegant ones! Technology and design come together in a new and unusual aesthetic, thanks to the exceptional flower shape around the tweeter membrane and also on the bass and center speaker baskets. However, this luxurious design was not only created from an aesthetic point of view. It is an expression of innovation that will allow the acoustic refraction at the edges of the tweeters to be less pronounced and adapt to the design of the speakers. An analogy can be found in the new Rolls-Royce engines for state-of-the-art aircraft, which have the same shape on the trailing edge. Exactly where the air comes out and the main turbulence is created. With the new design, these engines have achieved great benefits such as a 10 dB reduction in cabin noise and at the same time a 10% reduction in fuel consumption. However, this is not just a coincidence. The designs of high-end ESB speakers and Rolls-Royce engines are based on the same assumption, namely to reduce undesirable sound characteristics at the edge of the speakers and engines respectively, and to effectively direct the air flow outwards. However, this is only one of the many exclusive technologies that you will find in the 9000 model series. It includes a total of six high-end separate components, two 2-band component systems and three 3-band systems, which will amaze you not only with their sound, but also with their unconventional luxury design and exceptional materials.

ESB Audio 9.1T-28 tweeters

ESB Audio 9.1T-28 represent more advanced tweeters from the two options of the 9000 series. Individual models differ in the diameter of the dome and several other parameters and technologies, on the other hand, they have many technological and design solutions in common. The first thing you'll probably notice is the tweeter's beautiful design. However, it is not only an expression of Italian aesthetics, but it has its own justification. This design allows for perfect dimensional stability and ensures perfect connection of all parts with very tight tolerances, reducing distortion and improving performance. The special shape of the front part of the tweeter improves lateral reproduction, reduces reflection from car windows and creates ideal conditions for a wider listening angle. The diaphragm is made of lightweight semi-transparent silk, which is the perfect combination of lightness and strength and is probably the most suitable material for extremely realistic musical reproduction today. The shell is impregnated with resin with integrated suspension and is made in one piece, which also includes suspension. This significantly reduces weight and allows the tweeter to reach very high frequencies. The absence of joints prevents decay and various vibration phenomena. The exclusive technologies of the ESB Audio 9.1T-28 loudspeakers include the FCA and TCA system. The first-mentioned system represents a special design for controlling the air flow, ensuring a controllable and rapid release of the energy accumulated during the movement of the dome, without permanent oscillations occurring. This contributes to a more accurate and faithful response to the sound source and to the accuracy and overall quality of the audio experience. The TCA reverse airflow control system reduces turbulence and noise and controls the damping of the dome by metering the airflow. A copper Faraday ring helps reduce the inductance of the voice coil for minimal resistance at high frequencies. This provides a better high-frequency response that allows the speaker to better reproduce high-frequency sound more accurately. The reduction in inductance also contributes to better handling of fast transitions in audio signals. This can improve the speaker's ability to more accurately reproduce transient sound impulses. The tweeter's high-quality neodymium magnet ensures tremendous magnetic force even after hours of use when the tweeter will be hot. The tweeter also contains a secondary or superior magnet that serves to stabilize and regulate the magnetic flux and concentrate it just in front of the coil, increasing efficiency, manageable power, distortion and bandwidth. The special design of this magnetic assembly ensures that the lines of force are concentrated exactly where they are needed without leakage. Great attention has also been paid to the body, which is created using very precise CNC machines to very small tolerances to increase efficiency and performance. The large surface area helps to reduce the temperature so that the tweeter can operate safely. All magnet groups have been designed using sophisticated FEM software to optimize performance and reduce distortion. The voice coil is very light and can operate easily above 20kHz and guarantees a fast transient response and a very natural sound. Everything has been thought of during production, and it is worth noting the all-natural felt ring located just above the dome frame, which helps dampen reflections for a better focus of the soundstage. Included in the package are designer installation rings with a diameter of 95 mm, which ensure an optically coordinated installation in combination with the ESB Audio 9000 series center speakers.

Main features of ESB Audio 9.1T-28 tweeters

• 28mm diameter sz pure Japanese resin-impregnated silk.
• A light steel grille with a floral design and a second cover grille with the ESB logo.
• The front grill does not only have a cosmetic function, but acts as an acoustic lens, the shape of which significantly reduces side noise and reduces reflection from the car's windows.
• Felt ring to eliminate any parasitic vibrations.
• The super light aluminum voice coil uses a high-strength aluminum alloy to reduce its thickness and weight. The winding is also aluminum with a "cover" made of pure copper. In this way, the perfect combination of resistance and weight of the wire is achieved.
• The FCA airflow control system ensures a controllable and rapid release of the energy accumulated during the movement of the dome, without permanent oscillations.
• The TCA reverse airflow control system reduces turbulence and noise and controls the damping of the dome by metering the airflow.
• A copper Faraday ring drastically reduces voice coil inductance for minimal resistance at high frequencies well above 25kHz.
• The body is machined from a single piece of very low carbon steel to achieve higher magnetic flux, which means higher efficiency and lower distortion. The heavy weight ensures excellent cooling.
• The F52H neodymium main magnet represents the most suitable solution both for magnetic strength in relation to weight and for supporting high temperatures (120°C versus 80°C for a "classic" neodymium magnet).
• A secondary or superior magnet is used to stabilize and regulate the magnetic flux and concentrate it just ahead of the voice coil, increasing efficiency, manageable power, distortion and bandwidth.
• The pole plate is manufactured using a numerically controlled machine, not by stamping, which greatly reduces design tolerances in favor of performance.
• Magnetic plate made of extremely low carbon steel.
• Gold-plated copper terminals and extremely flexible connection cables with a high silver content to reduce electrical connection losses.
• The package includes mounting design rings with a diameter of 95 mm for an original appearance of the installation.

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 becoming a phenomenon of the time, and in 2005 a school dedicated exclusively to 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".
