ESB car audio 3.65 Pair of midrange 2.5"/65 mm

This 3.65 widerange speaker is designed to work in a 3-way system, with a woofer and a tweeter, or in a 2-way system where it can replace the tweeter. Conceived and built from scratch specifically, it offers exceptional transient response and extraordinary linearity, which translates into unparalleled clarity and natural reproduction of midrange. Distortion and non-linearities have been minimized through optimization of the motor and suspension dynamic behaviors.

The CNC aluminum center plug allows control, linearization and extension of high frequencies. The sharp edges, properly calculated, determine a refraction that linearizes and extends the spectrum of reproducible frequencies. The 20 mm voice coil offers good power handling and its reduced mass allows this component to be pushed well beyond the 20 KHz threshold. Basket in ABS reinforced with fiberglass. The basket was designed to achieve maximum in terms of torsional rigidity (bending resistance), but at the same time offers minimum resistance to air passage.

Pressed paper cone with waterproof treatment. It is widely recognized that paper cones represent the ideal combination of lightness, rigidity and the cone's ability to dampen any unwanted vibration. High damping single wave Perbunan® rubber. The Perbunan rubber edge is much more stable to temperature variations compared to standard rubber. The 20 mm voice coil uses an aluminum support and a double-layer winding technology of copper wires with aluminum core. N42 neodymium magnet: a type of magnet with performance significantly superior to "standard" magnets.
