ESB 3.25

Main Features

– The tweeter features a silk-impregnated thin fabric dome diaphragm for a smooth sound, with an outer suspension covered with a high-loss damping material to eliminate edge vibration and resonance. The dome is of extremely low mass and is much less susceptible to mechanical deformation than other tweeters, yet provides a smooth, linear and very extended response.
– The 25 mm voice coil has an aluminum support and very light copper-coated aluminum wire. The voice coil is ventilated and damped with iron-fluid oil.
– The special SVS ventilation design provides two benefits: optimal cooling of the voice coil and avoiding compressing the air at the back of the dome.
– The neodymium N42 magnet, a type of magnet with significantly higher performance than “standard” magnets, is optimized with computer simulations to get better efficiency and improve linearity.
