ESB 8.003UMA

– This special and exclusive component driver is a concept conceived way back in 1970’s. Its aim is to concentrate midrange and tweeter emissions in a virtual single point. This minimizes phase delays and irregularities at the crossover point.
– All the parts that make up this component have been made with the CNC process. This is a very expensive and time consuming manufacturing process, but ensures perfect geometry and impeccable aesthetics. A mix of precious materials such as brass, stainless steel and Avional aluminum are used together for a unique product.
– Each component uses a very large, vented neodymium motor magnet, optimized with computer simulations (FEA) to obtain a greater efficiency and improve linearity all along the voice coil’s excursion. The neodymium magnet is of a high-grade to eliminate magnetic loss at elevated temperatures and concentrate more force in less space.
– The tweeter uses a Torcon® soft dome, an exclusive Polyphenylene Sulfide (PPS) with a high performance fiber that offers superb heat resistance, low weight and excellent self-damping, to obtain a free resonance frequency response outside the audible frequency range.
– The midrange’s non-pressed cellulose pulp exponential cone, with a Vinylester resin coating, ensures a perfect balance between rigidity, weight, and self-damping. The cellulose pulp guarantees an extremely natural and linear reproduction, with an excellent extension at high frequencies.
– Great attention was given to the ventilation of the two components, through a single axial ventilation on the tweeter and multiple on the midrange. To improve control and damping, an acoustic resistance was adopted on both components.
– Combined, the two components are able to reproduce, with perfect linearity, the entire frequency spectrum from 95 Hz to 25 KHz.
