Woofer Esotar² 650

The 17 cm (6.5") diameter Esotar midrange/bass driver relies on the rigid, die-cast solid aluminum frame and Dynaudios characteristic MSP (Magnesium Silicate Polymer) diaphragm.

The MSP cone is a proprietary Dynaudio innovation, made in-house and featuring precisely-shaped, geometrically-optimized form to enable the smooth, optimized sound dispersion.

The voice coil diameter is exceptionally large at 75 mm, but by using extremely light aluminum wire wound on a Kapton former, the coil remains extremely lightweight. In conjunction with the powerful neodymium magnet, this low-mass driver construction provides excellent transient response, speed and precision.

Key features:
  • Diaphragm and dust cap moulded as one piece
  • Large 75 mm voice coil ensures high power handling
  • Internal double magnet system with vented pole piece
  • Internal double magnetsystem with neodymium magnet and vented pole piece
  • Aluminium voice coil wire provides for a low moving mass, wound on kapton former in a car
  • Rigid die-cast chassis with aerodynamically shaped ribs
  • Materials and parameters are optimized for the harsh environmental conditions in a car
  • Smooth high-frequency roll-off
  • Natural midrange reproduction
When used as part of a two-way speaker system, the midrange resolution of the Esotar² 650 is simply beyond reproach; mid-bass remains taught and accurate while always exhibiting perfect control at all volume levels. The Esotar² 650 perfectly reflects the innovation and performance that have established the Dynaudio Esotar drivers as the most advanced
high-performance transducers available.
