ESB 5.6K3U

The mission of this project was to create a loudspeaker system with an extremely high transient response (dynamic) in order to obtain 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 lighter and faster in its movements, favoring the sudden variations of movement transmitted by the music from the amplifier.

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. 5000 Series - Speaker Systems Woofer ​ • Great attention was paid to the axial and radial ventilation of the moving coil to ensure high power handling, reduced distortion, and increased durability. The stepped back allows a very long cone excursion. • Metal parts machined from solid and refined material are CNC machined for maximum magnetic flux linearity, and minimum magnetic loss. This reduces distortion at high power levels. • A pure copper ring was inserted into the magnetic field reduces harmonic distortion. • 25 mm CCAW (Copper Clad Aluminum Wire) double layer voice coil wound on an aluminum former provides exceptional power handling and compression-free reproduction to handle the most demanding musical passages. • The carbon fiber reinforced, polymer matrix composite exponential cone ensures an extraordinary rigidity combined with very low weight. • The eight twin-spoke, anti-resonant and self-extinguishing carbon fiber reinforced ABS frame ensures a drastic reduction of the cone's back reflections. The frame design assures high structural and torsional rigidity. This provides for perfect parts alignment and very tight construction tolerances. • The exclusive ESB design of the TSW (Twin Symmetrical Wave) double-wave rubber suspension allows an excursion with perfect progression and linearity. This feature ensures natural low-frequency reproduction at low as well as at high volumes. • Large Conex® spider allows a smooth and gentle run at low excursions and gently holds the cone at high excursions, thus increasing the useful frequency range. The UMA Unit ​ This special and exclusive component driver is a concept born way back in the 70’s. Its aim is to concentrate midrange 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 greater efficiency and improve linearity all along the voice coil’s excursion. The neodymium magnet is high grade type to eliminate magnetic losses at elevated temperatures and concentrating more force in less space. Great attention was given to the ventilation of the two components through multiple axial ventilation holes. Residual resonance is neutralized by the dB Cloth® under dome damping material. This extends the frequency response to the lower limits and reduces harmonic distortion. The high module carbon fiber domes with integrated soft cloth (tweeter) and synthetic foam (midrange) suspension offer superb heat resistance, low weight and excellent self-damping, with a natural and linear response and a very low frequency extension. The carbon fiber guarantees an extremely natural and linear reproduction with an excellent extension at the ends of the band. Combined together, the two components are able to reproduce, with perfect linearity, the entire spectrum from 500Hz to 25KHz. Small permanent magnets fix the tweeter and midrange grill in the correct position and permit easy removal for customization. 6.5"/165 mm Mid-Woofer Carbon fiber cone TWS® rubber surround 25 mm Copper and aluminum VC Y35 oversized magnet Aluminum former ABS housing Conex® progressive spider Motor metal part CNC machined Computer optimized design Nominal Impedance: 4 Ohm Nominal Power: 160 Watt Transient Power: 320 Watt Freq.
