ESB 5.UMA

5.UMA Parpris 2-Way Mid-High Unit • The carbon fiber reinforced, polymer matrix composite dome ensures extraordinary rigidity combined with a very low weight. • The 28 mm (tweeter) and 50 mm (midrange) aluminum voice coil allow the use of very high power for this kind of component. • The components use 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 magnet is a high-grade type to reduce magnetic loss at elevated temperatures and concentrate more energy in a small space. • All motor parts are made by the CNC process. This provides tighter tolerances and improved performance. • Great attention was paid to the axial and radial ventilation of the moving coil to ensure high power handling, with reduced distortion, and increased durability. The axial ventilation holes reduce the compression of the air at the back of the dome resulting in much reduced distortion and extended response into lower frequencies. • A special acoustic resistance helps to control the Ots. • Residual resonances are neutralized by the under-dome, dB Cloth® damping material. This extends the frequency response to the lower limits and reduces harmonic distortion. 1.1"/28 mm dome tweeter 2"/50 mm dome midrange High-grade neodymium magnet Carbon fiber dome Ferrofluid cooling and damping Acoustic resistance Qts control Motor metal parts CNC machined Under-dome dB Cloth® damping material Nominal Impedance: 4 Ohm Nominal Power Handling: 110 Watt Transient Power: 220 Watt Freq.
