The FlexMount system lets the driver clear factory grilles and shallow mounting depths that would stop a standard 4-inch speaker, while the aluminium dome tweeter extends response smoothly out to 25kHz for crisp detail. Built on Audiotec Fischer's COMPOSE i3 platform, it drops straight into a factory location without needing a separate crossover or tweeter pod.\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 100mm | 4\" midrange with 20mm aluminium dome tweeter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower handling RMS:\u003c\/strong\u003e 80W (120W max)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 91 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 100 Hz – 25,000 Hz\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e Outer diameter 98.0mm (3.86\"), installation diameter 89.0mm (3.50\"), installation depth 30.0mm (1.18\")\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 C100.2FM-S3 MK2 — official datasheet (PDF)\u003c\/a\u003e\u003c\/p\u003e","brand":"Helix","offers":[{"title":"Default Title","offer_id":49311445942427,"sku":"COMPOSE Ci3 C100.2FM-S3 MK2","price":425.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/0515\/9579\/files\/HELIX_COMPOSE_Ci3-C100-2FM-S3-MK2_EISA.jpg?v=1787025374","url":"https:\/\/www.integratedaudio.co\/products\/helix-ci3-c100-2fm-s3-mk2-4-2-way-coaxial-speaker-pair-flexmount-3%cf%89-integrated-audio","provider":"Integrated Audio","version":"1.0","type":"link"}
