This means better high-frequency response, enabling the speaker to reproduce high-frequency sounds more accurately. Reduced inductance contributes to better handling of rapid transitions of audio signals. This improves the speaker's ability to more accurately reproduce transient sound pulses.\u003cbr\u003e- FCA System: a special structure to control the flow of air moved by the dome. This creates a periodic damping resistance and dictates that the release of the energy accumulated in the movement of the dome occurs in a controlled and fast manner, without creating persistent oscillations. This contributes to a more precise and faithful response to the audio source and accuracy, and the overall quality of the audio experience.\u003cbr\u003e- Super light aluminum voice coil uses a high-strength aluminum alloy to reduce its thickness and its weight. The winding is also aluminum with a pure copper “skin”. This results in a perfect combination of resistance and weight of the wire.\u003cbr\u003e- Pure Japanese silk dome resin impregnated with integrated suspension. This catenary profile dome is made in a single piece that also includes the suspension. This greatly reduces the weight, allowing the tweeter to reproduce very high frequencies. The absence of joints prevents break-up and\/or vibrations.\u003cbr\u003e- Felt ring to eliminate any deleterious vibration.\u003cbr\u003e- Light stainless steel grill for dome protection.\u003cbr\u003e- The faceplate isn’t just cosmetic, but acts as an acoustic lens. Its shape dramatically reduces side refractions an unwanted occurrence in a car installations where windows create harmful refractions.\u003cbr\u003e- Super flexible cables with high silver content to reduce electrical connection losses.\u003cbr\u003e- Aluminum threaded fixing ring.\u003cbr\u003e- Finishing stainless steel ring (optional).\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan\u003e\u003cspan\u003e\u003cspan\u003eTechnical Specifications\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan\u003e\u003cspan\u003e- Nominal Impedance: 4 Ohm\u003cbr\u003e- Nominal Power Handling: 110 Watt\u003cbr\u003e- Transient Power: 220 Watt\u003cbr\u003e- Frequency Response: 1.4 KHz ~ 25 KHz\u003cbr\u003e- Sensitivity: 94.5 dB 2.83v\/1m\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"ESB","offers":[{"title":"Default Title","offer_id":62377562341745,"sku":"ESB-9.1T-28","price":1299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3341\/7329\/files\/c7fdc58d-865901_c41ee1e6cf3247e8afc1ab9ab02907ea_mv2.png?v=1758413225","url":"https:\/\/davillecustoms.com\/uk\/products\/esb-audio-9000-series-9-1t-28-1-1-28-mm-high-end-dome-tweeter","provider":"Daville Customs","version":"1.0","type":"link"}
