ESB Audio 5000 series – 5.6K3

ESB 5000 series 5.6K3 is the new series is the philosophy of this project is to create a loudspeaker system with an extremely high transient response (dynamic), in order to obtain a music reproduction with a more realistic impact and involvement. To achieve this, the main goal was to reduce the moving masses in order to make the mobile part of the loudspeaker light and fast in its movements, favoring the sudden variations of movement transmitted by the piece of music through the amplifier. Elegance and Technology, all Italian

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 allows the use of very high power for this kind of component. The tweeter uses a very large, vented neodymium motor magnet optimized with computer simulations (FEA) to obtain a greater efficiency and improve linearity along all the voice coil’s excursion. Neodymium magnet is a high-grade type to reduce magnetic loss at elevated temperature and concentrate more energy in a small space. All motor parts are made by CNC process. This gives tighter tolerances and improved performance. Great attention was paid to the axial and radial ventilation of the moving coil, this 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 with greatly reduced distortion and extended response into lower frequencies. A special acoustic resistance helps to control the Qts. Residual resonances are killed by the under-dome, dB Cloth® damping material, this extends the frequency response to the lower limits and reduces harmonic distortion.
