ESB Audio 9.1T-25 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-25 tweeters

ESB Audio 9.1T-25 represent one of the two tweeter 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 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 tweeter's high-quality neodymium magnet ensures tremendous magnetic force even after hours of use when the tweeter will be hot. The voice coil is very light and can operate easily above 20kHz and guarantees a fast transient response and a very natural sound. Also worth mentioning is the series of calibrated axial holes that connect the interior of the tweeter to the rear chamber obtained by joining the connector cover. This helps lower the resonant frequency, improves ventilation and reduces the impedance peak, making the response longer and more linear.

Main features of ESB Audio 9.1T-25 tweeters

• Calota with a diameter of 28 mm made of resin-impregnated silk.
• Lightweight removable steel grille with floral design and ESB logo.
• Felt damper under the hood made of pure wool with long fibers, which is the most effective material for absorbing and damping medium and high frequencies.
• The super-light 25mm aluminum voice coil with aluminum copper winding contributes significantly to the wide frequency range of this tweeter.
• The body of the tweeter is made of durable ABS plastic with excellent self-damping.
• Magnetic plate made of extremely low carbon steel.
• 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).
• The pole plate is manufactured using a numerically controlled machine, not by stamping, which greatly reduces design tolerances in favor of performance.
• The plate has twelve axial holes in the lower part created to eliminate the air back pressure caused by the movement of the dome. This makes it possible to reduce the distortions that would inevitably occur due to the deformation of the fine silk and also helps to reduce the frequency resonance of the tweeter.
• Gold-plated copper terminals and extremely flexible connection cables with a high silver content to reduce electrical connection losses.
• In the package you will find 8 parts of mounting accessories for variable installation.
• The rear side of the tweeter is equipped with a threaded hole, which significantly increases the possibilities of fixing it in non-traditional conditions inside cars.

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 is part of the Italian company Apex Group, together with the American manufacturer of audiophile amplifiers and DSP processors Zapco. The offer includes several model lines of speakers, led by the super high-end three-way Diecimila system, which represents probably the highest 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".
