ESB 8.6K3U LE 3-Way Speaker System with UMA Limited Edition

The 8000 series can be considered the direct heir of the legendary 7000 series, which scored many successes in the world of Italian car stereo and beyond. We renewed a range of speakers already in itself exceptional, with the aid of the best technologies now available. The goal was to renew a variety of speakers in itself exceptional, with the help of the latest technologies and the use of the best materials available today; always with an eye to the versatility of installation. Key to the development of this type of system in the car was so take full advantage of their exceptional musicality. In the 8000 series every detail was taken care of with the utmost care, from the choice of materials to the forms, from the construction and finishing of the baskets to the ventilation systems of magnets and coils. It has improved what was thought to be difficult to improve and we strongly believe that it has laid the foundation for another decade of success. Tweeter: The large diameter 28 mm voice coil is the right compromise between the lightness of the classic 25 mm coil and the great power management of 32 mm coils. Body made of 7000 aluminum alloy and brass, entirely worked by numerical control (CNC). This makes the structure very rigid and with practically zero tolerances to the benefit of consistency of performance and maximum linearity. Torcon® soft dome, an exclusive Polyphenylene Sulfide (PPS) with a high performance fiber that offers superb heat resistance, low weight and excellent self damping., get a free resonance frequency response until over audible frequency. O52 oversized high quality neodymium magnet. This "engine" guarantees a perfectly linear and constant magnetic flux over the entire working range of the tweeter, guaranteeing an extremely linear and neutral response both at low and high volume. Furthermore, a pure copper ring was added to reduce the harmonic distortions. Woofer: Basket made of 7000 aluminum alloy entirely worked by the numerical control (CNC). Cone in non-pressed paper, as well as the dust cover. The best compromise between damping and rigidity for an extremely natural sound without colorations or alterations. A water repellent treatment also makes it suitable for applications in harsh environments. A careful study supported by FEM analysis has allowed us to design the metal parts of the magnet in order to maximize the flow exactly around the moving coil, and make it linear throughout the entire excursion. Ventilation is ensured by a large opening at the bottom where its conformation reduces the noise of possible turbulence to inaudible levels. The large diameter voice coil uses an aluminum support to better disperse the temperature. Furthermore, the entire voice coil is exposed to the outside air through large slits in the basket (protected by a dust sponge).The speaker terminal, our exclusive design, accepts large section cables.
