ESB 8.003UMA

8.003UMA Parpris 2-Way Mid-High Unit This special and exclusive component driver is a concept born way back in 70'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 (you can read more in The Phase). All the parts that make up this component have been made with the CNC process. This is very expensive and time consuming, 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 a high-grade type 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 fibers that offers superb heat resistance, low weight and excellent self-damping, resulting in a resonance-free 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. 28 mm aluminum VC (tweeter) Torcon® soft dome (tweeter) High-grade neodymium magnet Ferrofluid cooling and damping NPPV exponential cone (mid) Conex progressive spider (mid) Motor metal parts CNC machined Under-dome dB Cloth® damping material Nominal Impedance: 4 Ohm Nominal Power Handling: 120 Watt Transient Power: 240 Watt Freq.
