ESB - Over Half A Century Of Electroacoustic Brilliance
Electroacoustic maestro ESB was officially founded in 1972. Fast forward over fifty years and it's still regarded as a world leader in loudspeaker design. During it's tenure this audacious Italian company has mastered the art of high-end speaker design, acquiring a wealth of experience and knowledge difficult to find elsewhere. Some of the most important milestones in the history of high fidelity audio have been marked by ESB. Whether it be ideologies, insights, applications of electroacoustic principles or just plain passion for high fidelity audio; achieving these milestones have become the very foundations of the company's history.

9000 Series – Where Aeronautical Engineering And Speaker Development Collide
The new 9000 series components are the zenith of the ESB stable and represent some of the most technologically advanced car audio speakers ever produced. They’re also some of the most aesthetic pleasing too. Incredible technology and impeccable design acumen come together to form the Novemila series, culminating with that peculiar geometry incorporated into the flanges of the tweeters and the baskets of the midrange drivers. For that shape is not employed simply for comeliness, rather it’s expression of upmost innovation and represents an avowed masterclass in airflow manipulation.

Design Ideologies
The 9000 series component speakers represent some of the most technologically advanced car speakers ever produced. The 9.6W is a set of 6.5″ midrange / midbass drivers destined to to leave the competition far in its wake.

Technology and design come together in the 9000 series in a new and unusual aesthetic, thanks primarily to the particular flower shaped flanges around the tweeter dome and in the baskets of the cone speakers. However this unique shape is not simply to achieve an aesthetic form factor, rather it’s the very essence of an innovation that makes these components so brilliant. Meticulously designed; the flower shape seeks to address the acoustic refraction on the edges of the dome speakers and backside of the cones which normally have a large dispersion azimuth. The airflow would be impeded less and move far more fluidly if the vortices were split as it moved outward. A similar design can be found on the back of Rolls Royce Trent 1000 aircraft engines. The saw-tooth cowling at the rear of the engine, where the enormous bypass thrust emanates from; is sliced as it flows out. Instead of titanic turbulence you get wonderfully clean jet streams with very little external noise and chuffing. Using this technology is no coincidence. Whether it be speakers or jet engines the goal is the same; to reduce harmful turbulence and at the edge of the device.

Design Features
During the development stage of the 9000 nothing was left to chance. Literally every detail was scrutinised from beginning to end, from the choice of materials used through to wind tunnel testing to ensure absolutely no stone was left unturned in the manufacture of these drivers.

Bedrock Solid Foundation – The 9.6W Woofers
Last but not least is the larger woofer. It features just as much innovative technology as the smaller drivers. Some of the main features are as follows.

The Aerodynamic Advantage – The Basket
The aluminium alloy basket is designed with very open rear chambers to eliminate back pressure under the cone and too allow copious amounts of air to enter.

The Engine Room – The Motor
The large diameter super light aluminium voice coil uses a high-strength aluminium alloy which allows ESB to reduce its thickness and therefore its weight. The winding is also aluminium with the a skin of pure copper. Within this is a CNC machined low carbon steel pole yoke. The whole motor group has been designed with the help of FEM software to concentrate all the magnetic flux in the working point: in front of the voice coil. Its enormous mass guarantees excellent temperature dissipation. Around the voice coil resides an oversized neodymium magnet with high resistance to high temperatures. The total magnetic force is very high compared to similar products. Below this a CNC machined pole plate featuring a series of nodes channelling the cooling air to increase the performance of the woofer and its longevity.

Suspended Animation – The Suspension
The lower portion of the suspension is formed by a Conex spider, balanced to obtain the same compliance in both movements upper and lower. This guarantees very low distortion. The spider is supported by glass fiber reinforcement to resist at high temperatures. This particular design makes it possible to insert the spider inside the voice coil leaving a passage of cooling air free. Top side an NBL rubber surround has a shape designed to ensure very smooth movement at very low excursion, becoming increasingly controlled as the excursion increases and approaches the limit. Along with the spider this helps to make this speaker extremely dynamic and capable of handling extreme kinetic demands.

True Brute Strength – The Cone
The woofer features a high modulus carbon fibre diaphragm moulded with M+F system which guarantees perfect geometry and perfect adhesion of the carbon fibres to each other. The result is an object 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. Connection between coil and cone is via pressed paper, as it helps to dampen the parasitic vibrations of the carbon cone. The cone also features a carbon fibre dust cap, the function of this part is fundamental on a woofer with a voice coil of this size. It’s shape is so for strength, and it’s the perfect combination of lightness and rigidity to ensure a deep, fast and dynamic bass.

Protection Boasting Looks And Purpose
All 9000 series components have optional matching grilles that are CNC machined from solid aluminum. These can be ordered separately to the speakers. Please contact us if you require either.
