The catenary curvature ensures a wide sound dispersion of the tweeter. The felt damper under the dome improves the acoustic phase by absorbing sounds reflected from the magnetic structure that bounce back through the dome. High-quality neodymium magnets. Not all magnets of the same size are equally strong. This high-quality (N-52), high-energy magnet provides high resistance to demagnetization and is over 25% stronger with the same mass than more common lower-grade magnets. By using a high-quality magnet, efficiency rises to an exceptional level, resulting in a high volume yet controlled speaker. The main body is glass fiber-filled ABS plastic for improved strength. An acoustic resistance component inside the vent hole helps to control and damp the diaphragm's movement, reducing distortion and producing a linear impedance curve for better speaker\/amplifier coupling. CNC-machined ultra-low carbon steel alloy plate. This type of manufacturing process ensures perfect flatness, so it sits perfectly on the magnet without reducing critical magnetic flux. The large aluminum copper-clad ventilated voice coil can handle very high power while reproducing music with extreme realism and high dynamics. The copper-clad aluminum wire voice coil is very lightweight and has excellent heat dissipation\/capacity. A high-quality protective stainless steel grille, with perforations calibrated to act as an acoustic lens, ensures sound radiation on the speaker axis and also curves to the sides, which is very useful in car audio installations where speaker placement often results in off-axis listening. CNC-machined aluminum alloy flange, flush-mounted.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wixui-rich-text\" data-testid=\"richTextElement\"\u003e\n\u003ch3 class=\"font_2 wixui-rich-text__text\"\u003e\u003cspan class=\"color_36 wixui-rich-text__text\"\u003e\u003cspan class=\"wixui-rich-text__text\"\u003eTechnical specifications\u003c\/span\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wixui-rich-text\" data-testid=\"richTextElement\"\u003e\n\u003cul\u003e\n\u003cli class=\"font_9 wixui-rich-text__text\"\u003e\u003cspan class=\"color_36 wixui-rich-text__text\"\u003e\u003cspan class=\"wixui-rich-text__text\"\u003eNominal impedance: 4 Ohm\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"font_9 wixui-rich-text__text\"\u003e\u003cspan class=\"color_36 wixui-rich-text__text\"\u003e\u003cspan class=\"wixui-rich-text__text\"\u003eNominal power handling: 100 W\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"font_9 wixui-rich-text__text\"\u003e\u003cspan class=\"color_36 wixui-rich-text__text\"\u003e\u003cspan class=\"wixui-rich-text__text\"\u003eTransient power: 200 W\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"font_9 wixui-rich-text__text\"\u003e\u003cspan class=\"color_36 wixui-rich-text__text\"\u003e\u003cspan class=\"wixui-rich-text__text\"\u003eFrequency response: 1.5 kHz ~ 22 kHz\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"font_9 wixui-rich-text__text\"\u003e\u003cspan class=\"color_36 wixui-rich-text__text\"\u003e\u003cspan class=\"wixui-rich-text__text\"\u003eSensitivity: 93.5 dB 2.83 V\/1 m\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"ESB Audio","offers":[{"title":"Default Title","offer_id":56763377615223,"sku":"4.28","price":139.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/5159\/4359\/files\/4.28_1.jpg?v=1771502390","url":"https:\/\/hifikaupat.fi\/en\/products\/esb-audio-4-28-1-1-28-mm-dome-tweeter-pair","provider":"Hifikaupat.fi ","version":"1.0","type":"link"}
