ESB 8.003UMA
TWEETER 2-WAY MID-HIGH UNIT

Main features include 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. Technical Specifications - Nominal Impedance: 4 Ohm; Nominal Power Handling: 120 Watt; Transient Power: 240 Watt; Frequency Response: 95 Hz ~ 25 KHz; Sensitivity: 94 dB 2.83v/1m.
