The integrated dampened coupling volume and pure lamb's wool enable a low resonance frequency for deep acoustic coupling. Its sturdy aluminium housing and compact design make it versatile for various installation demands, with flush mount and angle mount pods included. The FlexMount20 system allows for car-specific installation in the original mounting position, while optional WireKits provide plug-and-play connectivity to the original wiring harness.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eType\u003c\/strong\u003e: Tweeter\u003cbr\u003e\u003cstrong\u003eDiameter\u003c\/strong\u003e: 20 mm\u003cbr\u003e\u003cstrong\u003eImpedance\u003c\/strong\u003e: 4 Ohm\u003cbr\u003e\u003cstrong\u003eDC Resistance\u003c\/strong\u003e: 3.4 Ohm\u003cbr\u003e\u003cstrong\u003eFrequency Response\u003c\/strong\u003e: 1,500 Hz - 30,000 Hz\u003cbr\u003e\u003cstrong\u003eResonance Frequency\u003c\/strong\u003e: 950 Hz\u003cbr\u003e\u003cstrong\u003eSensitivity\u003c\/strong\u003e: 91.0 dB @ 2.83V\/1m\u003cbr\u003e\u003cstrong\u003eVoice Coil Diameter\u003c\/strong\u003e: 20 mm\u003cbr\u003e\u003cstrong\u003eCone Material\u003c\/strong\u003e: Silk dome with coupling volume\u003cbr\u003e\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 32 mm\u003cbr\u003e\u003cstrong\u003eInstallation Diameter\u003c\/strong\u003e: 27.2 mm\u003cbr\u003e\u003cstrong\u003eInstallation Depth\u003c\/strong\u003e: 19 mm\u003cbr\u003e\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Aluminium\u003cbr\u003e\u003cstrong\u003eMagnet Type\u003c\/strong\u003e: Neodymium\u003cbr\u003e\u003cstrong\u003eMounting System\u003c\/strong\u003e: FlexMount20\u003cbr\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e: FlexMount20, WireKits\u003cbr\u003e\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Germany\u003cbr\u003e","brand":"HELIX","offers":[{"title":"Default Title","offer_id":53772609618257,"sku":"CI21001","price":349.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/2772\/5905\/files\/HELIX-Ci7-T20FM-SC-Explosion-EISA_47c33c1f-f2a5-46dc-8751-cad319fd739c.jpg?v=1778706665","url":"https:\/\/shoponyxac.co.uk\/products\/helix-ci7-t20fm-sc-silk-dome-tweeter-20mm-4-ohm","provider":"Onyx Auto Care","version":"1.0","type":"link"}
