6.5”/165 mm Mid-Woofer

– 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.
