ESB Audio 5000 Series 2-Way Speaker System
5000 Speaker Series
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.
5.028
1.1"/28 mm Dome Tweeter
Main Features
- The carbon fiber reinforced, polymer matrix, composite dome, ensures extraordinary rigidity combined with very low weight.
- The 28 mm 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 improved linearity all along the voice coil’s excursion. The neodymium magnet is of a high-grade to reduce magnetic loss at elevated temperatures and concentrates 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 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 tweeter 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 by clips and replaced with an adapter for back side installation.
- For tweeter flush mounting, use the included 4 chrome front screws, or for surface mounting, use the supplied mounting cup.

5.165
6.5"/165 mm Mid-Woofer
Main Features
- The magnet motor is optimized with FEA simulation to ensure a perfectly symmetrical magnetic flux in both directions of movement of the cone.
- 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 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 is inserted into the magnetic field to reduce harmonic distortion.
- A 25 mm CCAW (Copper Clad Aluminum Wire) double layer voice coil is wound on an aluminum former for 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. This frame design assures high structural and torsional rigidity. This is necessary for perfect parts alignment and very tight construction tolerances.
- The exclusive ESB designed 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 volume.
- The 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.
