Description

ESB Audio 5.6K3U (Active) New Speaker Series

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.

The UMA Unit

This special and exclusive component driver is a concept born way back in 70’s, its aim is to concentrate medium and tweeter emissions in a single virtual point. This minimizes phase delays and irregularities at the crossover point. (You can read more in The Phase page). Both components use a very large neodymium motor magnet optimized with computer simulations (FEA) to obtain a great efficiency and improve linearity along all voice coil excursion. Neodymium magnet is an high grade type for eliminate magnetic losses at elevate temperature and concentrate more force in less space.

Great attention was given to the ventilation of the two components, through multiple axial ventilation holes. Residual resonance are killed by the under dome damping material named dB Cloth®. This extends the frequency response to the lower limits and reduces harmonic distortion. The high modul carbon fiber domes with integrated soft cloth (tweeter) and synthetic foam (midrange) suspension offers superb heat resistance, low weight and excellent self damping, with a natural and linear response, and a very low frequency extension. The carbon fiber guarantee an extremely natural and linear reproduction, with an excellent extension at the ends of the band.

Combined together the two component are able to reproduce with perfect linearity all spectrum from 500Hz to 25KHz. Small permanent magnets fix the tweeter and midrange grill in correct position and these are easy to remove for customize.
