The ESB 3.25 high-frequency speakers from the 3000 series are designed to bring clarity and precision to high-quality car audio systems. These tweeters feature a silk-impregnated thin fabric dome that ensures a linear response, while the 25 mm voice coil, made of copper-coated aluminum wire with aluminum support, is kept cool and damped using ferrofluid oil. To maintain performance and prevent air compression, the speakers utilize a Neodymium N42 magnet paired with an SVS ventilation system. With a nominal power handling of 90 Watt and a transient peak of 180 Watt, these 4 Ohm speakers deliver a frequency response ranging from 900 Hz up to 25 KHz. Their sensitivity of 92 dB allows for efficient sound reproduction, while high-loss damping material on the outer suspension eliminates edge vibration and resonance. Engineered in Italy, this pair provides a refined listening experience for those who value technical accuracy in their vehicle's soundstage.
