Its concentric design creates a true point sound source for precise, time-coherent audio reproduction. The glass bead-reinforced high-tech polymer basket ensures maximum stability with minimal resonance, while the 3-ohm impedance and 92dB sensitivity deliver exceptional efficiency with HELIX and MATCH amplifiers. Made in Germany, it features the ProConnect terminal for secure, reversible connections and is compatible with optional FlexMount165 adapter rings for vehicle-specific installation.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eType\u003c\/strong\u003e: 2-way coaxial coincidence speaker\u003cbr\u003e\u003cstrong\u003eWoofer Size\u003c\/strong\u003e: 165 mm\u003cbr\u003e\u003cstrong\u003eTweeter Size\u003c\/strong\u003e: 20 mm\u003cbr\u003e\u003cstrong\u003eTweeter Type\u003c\/strong\u003e: Silk dome with coupling volume\u003cbr\u003e\u003cstrong\u003eCone Material\u003c\/strong\u003e: UHD (Ultra High Damping) paper\u003cbr\u003e\u003cstrong\u003eBasket Material\u003c\/strong\u003e: High-tech polymer with glass bead reinforcement\u003cbr\u003e\u003cstrong\u003eImpedance\u003c\/strong\u003e: 3 Ω\u003cbr\u003e\u003cstrong\u003eRMS Power Handling\u003c\/strong\u003e: 150 W\u003cbr\u003e\u003cstrong\u003eMax Power Handling\u003c\/strong\u003e: 225 W\u003cbr\u003e\u003cstrong\u003eFrequency Response\u003c\/strong\u003e: 50 Hz - 30,000 Hz\u003cbr\u003e\u003cstrong\u003eSensitivity\u003c\/strong\u003e: 92 dB @ 2.83V\/1m\u003cbr\u003e\u003cstrong\u003eVoice Coil Diameter\u003c\/strong\u003e: 37 mm\u003cbr\u003e\u003cstrong\u003eMounting Diameter\u003c\/strong\u003e: 142 mm\u003cbr\u003e\u003cstrong\u003eMounting Depth\u003c\/strong\u003e: 65.8 mm\u003cbr\u003e\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 165 mm\u003cbr\u003e\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Germany\u003cbr\u003e","brand":"HELIX","offers":[{"title":"Default Title","offer_id":53773305741649,"sku":"CI22620","price":349.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/2772\/5905\/files\/HELIX-COMPOSE-Ci7-C165-2FM-S3_f864f0e0-1ff5-4d68-a407-91908726f821.jpg?v=1778713324","url":"https:\/\/shoponyxac.co.uk\/products\/helix-ci7-c165-2fm-s3-2-way-coaxial-coincidence-speaker-165mm","provider":"Onyx Auto Care","version":"1.0","type":"link"}
