9000

New High-End Speaker Series

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

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.

Tweeter Main Features

 

• Tweeter pole yoke made of ultra-low carbon steel to achieve higher magnetic flux which means higher efficiency and lower distortion. A series of calibrated axial holes connect the internal part of the tweeter with the rear chamber obtained from the coupling of the connector cover. This helps to lower the resonant frequency, improves ventilation and lowers the impedance peak making the response more extended and linear.
• Neodymium magnet.
• Pole plate made of very low carbon steel.
• Tweeter body in ABS.
• Felt damper under the dome to reduce parasitic vibrations and resonances.
• Golden brass terminals.
• Super-light aluminum voice coil. It uses a high-strength aluminum alloy so as to reduce its thickness and therefore weight. The winding is also made of aluminum with the "skin" of pure copper. In this way a perfect combination of resistance and weight of the wire is obtained.
• Silk dome treated with resin.
• Kraft paper seal.
• Sponge dust filter

Midrange Main Features

 

• Low carbon steel pole yoke machined entirely by numerical control. The entire motor unit was designed to be able to concentrate all the magnetic flux in the working point: in front of the voice coil.
• CDT system to regulate and control the air flow generated by the movement of the cone, helps the cooling of the voice coil and controls the damping of the cone.
• Neodymium magnet for an unusual magnetic force for a medium of this diameter.
• Pole plate obtained with a numerically controlled lathe and not by molding, this drastically reduces construction tolerances to the benefit of performance.
• Aluminum alloy basket with very open design to eliminate counter-pressures under the cone.
• Super-light aluminum voice coil. It uses a high-strength aluminum alloy so as to reduce its thickness and therefore weight. The winding is also made of aluminum with the "skin" of pure copper. In this way a perfect combination of resistance and weight is obtained.

TRENT Motor

As said, the particular shape of flanges and baskets was not born for an aesthetic factor. It is an expression of innovation. That requires that the acoustic refraction on the edges of the speakers can be less damaging if the the outer edge is not equidistant from the center. An analogy can be found in the new Rolls Royce aircraft’s engines that have the same shape on the back edge (where the greatest turbulences are). This is not just a random analogy, both are constructive choices: effectively channel the air flow outside. And that's just the inspiration for a series full of tech content.
