9000

New High-End Speaker Series

 

The new 9000 series are one of the most technologically advanced car audio speakers ever produced, and also one of the most elegant. Technology and design come together in a new and unusual aesthetic, thanks to the particular flower shape of the flanges around the speaker dome, then also in the baskets of the cone speaker. But the particular shape was not born only for an aesthetic factor.

It is an expression of  innovation.

Most advanced aircraft engine and speakers technology

9000 Series

 

The new 9000 Series is an expression of an innovation, that requires that the acoustic refraction on the edges of the dome speakers (which have normally large dispersion) may be less damaging if the board is not equidistant from the dome's center, but varies discontinuously according to the new design of the 9000 series speakers. An analogy can be found in the new Rolls Royce engines for the last aircraft that reproduce the same form on the back edge (precisely where the air comes out and where they form the major turbulence). With the new design these engines have achieved great advantages such as reducing the noise in the cabin (about 10dB) and the reduction of fuel consumption (about 10%). this is not just a random analogy, both are constructive choices and both came from the same premise: Reduce the harmful turmoil in the edge of the speakers.

ESB 9000 Series Woofers

Woofer - Main Features

 

• Entirely numerically controlled low carbon steel pole yoke. The whole motor group has been designed with the help of FEM software in order to concentrate all the magnetic flux in the working point: in front of the voice coil. Its enormous mass guarantees excellent temperature dissipation.
• Oversized neodymium magnet with high resistance to high temperatures. The total magnetic force is very high compared to similar products
• Pole plate obtained with a numerically controlled machine and not by stamping, this drastically reduces construction tolerances to the advantage of performance. A series of channels conveys the cooling air to increase the performance of the woofer and its longevity.
• Aluminum alloy basket with very open design to eliminate back pressure under the cone.
• Large diameter (76 mm) super light aluminum voice coil. It uses a high-strength aluminum alloy so as to be able to reduce its thickness and therefore its weight. The winding is also aluminum with the "skin" in pure copper.
• Spider support in glass fiber reinforced with resin to resist at high temperatures. This particular design makes it possible to insert the spider inside the voice coil, and leaves the passage of cooling air free.
• Conex spider, balanced to obtain the same compliance in both movements: upper and lower, this guarantees very low distortion.
• Connection between coil and cone with pressed paper, it helps to dampen the parasitic vibrations of the carbon cone.
• High modulus carbon fiber cone molded with M+F system which guarantees perfect geometry and perfect adhesion of the carbon fibers to each other, obtaining a product of extreme rigidity, with a very high sound transmission capacity but also excellent internal damping, all for a very low weight and constant performance as it is insensitive to changes in humidity and temperature.
• Butyl rubber rim designed to obtain an exponential resistance progression in order to control the cone at large displacements but at the same time not affect the movements at very low volume.
• Carbon fiber dust cap like the cone, the function of this part is fundamental on a woofer with a voice coil of this size, its shape and rigidity are the perfect combination of lightness and rigidity to ensure a deep, fast and dynamic bass.

Tweeter - Main Features

 

TCA System for back air flow control: reduces turbulence, noise, and controls the damping of the dome by dosing the passage of the air.

Body machined from a single piece of ultra-low carbon steel to achieve higher magnetic flux, which means higher efficiency and lower distortion. The large mass ensures excellent cooling.

Main magnet in F52H neodymium, the best both for the magnetic force in relation to the mass, and for the high temperatures support (of 120° against the 80° of a "classic" neodymium magnet).

Pole plate obtained with a numerically controlled machine and not by stamping, this drastically reduces construction tolerances to the advantage of performance

Secondary or superior magnet, used to stabilize and regulate the magnetic flux and concentrate it only in front of the voice coil, increasing efficiency, manageable power, distortion and bandwidth.

Faraday ring: this copper ring drastically reduces the inductance of the voice coil, in this way the bandwidth of the tweeter can extend well above 25KHz.

Super light aluminum voice coil. It uses a high-strength aluminum alloy so as to be able to reduce its thickness and therefore its weight. The winding is also aluminum with the "skin" in pure copper. In this way a perfect combination of resistance and weight of the wire is obtained.

Dome in silk treated with resin.

Felt ring to eliminate any parasitic vibration.

Acoustic lens designed to regulate and optimize tweeter dispersion.
