ESB car audio 3.90 Serie 3000 Pair of 3.5"/90 mm midrange

Basket in ABS reinforced with fiberglass. The basket has been designed to achieve maximum in terms of torsional rigidity (resistance to bending), but at the same time offers minimum resistance to air passage. Cone in pressed paper with water-repellent treatment. It is widely recognized that paper cones are the ideal combination of lightness, rigidity and the cone's ability to dampen any unwanted vibration.

Surround in symmetrical dual-wave rubber. Perbunan® rubber surround is much more stable to temperature variations compared to standard rubber. The 20 mm voice coil uses an aluminum support with a dual-layer winding technology of copper wires with an aluminum core. High-quality ferrite magnet, a type of magnet with performance significantly superior to "standard" magnets.

3.90 Features

  • Treated paper cone
  • Perbunan rubber suspension
  • Y-35 ferrite magnet
  • Reinforced ABS basket
  • Balanced cotton spider
  • Dual-layer voice coil
