ESB 3.28

PARPRIS 3.28 The 3000 Series tweeters use a silk-impregnated, thin fabric dome diaphragm for a smooth sound, with an outer suspension covered in a high-loss damping material to eliminate edge vibration and resonance. Aluminum supports with very light copper-coated aluminum wire. The coils are ventilated and damped with iron-fluid oil. Tweeters use high-grade, N-42 neodymium magnets, optimized with computer simulations for better efficiency and improved linearity. The special ventilation design, called SVS (Surround Vented System), provides two benefits: optimal cooling of the voice coil and avoiding compressing air at the back of the dome. - The tweeter uses a Torcon® 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 it provides a smooth, linear and very extended response. - The 28 mm voice coil has an aluminum support and very light copper-coated aluminum wire. The 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. 1.1"/28 mm Dome Tweeter Torcon® soft dome High-loss damping suspension N42 neodymium magnet SVS ventilation design 28 mm voice coil Optimized computer design Nominal Impedance: 4 Ohm Nominal Power Handling: 90 Watt Transient Power: 180 Watt Freq.
