The updated MK2 cone and voice coil deliver 92dB sensitivity and reach down to 60Hz, giving genuinely useful bass extension for a coaxial driver. It's a practical way to lift factory sound quality without cutting into doors for a full component set.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct specifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Helix COMPOSE Ci3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker type:\u003c\/strong\u003e Coaxial | 2-Way\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 165mm | 6.5\" midbass with 20mm tweeter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower handling RMS:\u003c\/strong\u003e 100W (150W max)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 92 dB @ 2.83V\/1m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoice coil x impedance:\u003c\/strong\u003e 1 x 3Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 60 Hz – 25,000 Hz\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e Outer diameter 165.0mm (6.50\"), installation diameter 142.0mm (5.59\"), installation depth 60.7mm (2.39\")\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDownloads:\u003c\/strong\u003e \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/0515\/9579\/files\/HELIX_COMPOSE_i3_MK2_Speaker-Systems_22-04-2025_054030c0-f3fa-47eb-9814-c5ba4f39ea0c.pdf?v=1787749173\"\u003eHELIX Ci3 C165.2FM-S3 MK2 — official datasheet (PDF)\u003c\/a\u003e\u003c\/p\u003e","brand":"Helix","offers":[{"title":"Default Title","offer_id":49311445418139,"sku":"COMPOSE Ci3 C165.2FM-S3 MK2","price":395.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/0515\/9579\/files\/HELIX_COMPOSE_Ci3-C165-2FM-S3-MK2.jpg?v=1787025363","url":"https:\/\/www.integratedaudio.co\/products\/helix-ci3-c165-2fm-s3-mk2-6-5-2-way-coaxial-speaker-pair-flexmount-3%cf%89-integrated-audio","provider":"Integrated Audio","version":"1.0","type":"link"}
