WOOFER 6.5”/165 MM MID-WOOFER

Main features include 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.
