ESB 5.050

5.050 PARPRIS 2"/50 mm Dome Midrange - The carbon fiber reinforced, polymer matrix, composite dome ensures extraordinary rigidity combined with very low weight. - The large (50 mm) aluminum voice coil allows the use of much higher power for this kind of component. - This midrange uses a very large, vented, neodymium motor magnet, optimized with computer simulations (FEA) to obtain a greater efficiency and improved linearity all along the voice coil’s excursion. The neodymium magnet is of a high-grade to reduce magnetic loss at elevated temperature and concentrate more energy in a small space. - All motor parts are made by CNC process for tighter tolerances and improved performance. - Great attention was paid to the axial and radial ventilation of the moving coil to ensure high power handling, reduced distortion, and high durability. The axial ventilation holes reduce the compression of the air at the back of the dome for a great reduction in distortion and an extended response into lower frequencies. - A special acoustic resistance helps to control the midrange 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. - The faceplate can be removed and replaced with an adapter for rear mount installation. 50 mm aluminum voice coil High-grade neodymium magnet Carbon fiber dome Ferrofluid cooling and damping Acoustic resistance Qts control Computer optimized design 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.
