Its extended response out to 25kHz means it can be safely crossed as low as 3,000Hz with a steep 24dB slope, giving it real flexibility across passive component sets and active setups alike.\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 Tweeter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 20mm | 0.75\"\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 4Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 2,000 Hz – 25,000 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended high-pass:\u003c\/strong\u003e 6dB\/oct above 5,000Hz | 12dB\/oct above 3,500Hz | 24dB\/oct above 3,000Hz\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e Outer diameter 32mm (1.26\"), installation diameter 28mm (1.10\"), installation depth 9.8mm (0.39\")\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_Tweeter_22-04-2025_cd405217-2017-4c45-ab6f-848c0d639d7c.pdf?v=1787749173\"\u003eHELIX Ci3 T20FM-AL MK2 — official datasheet (PDF)\u003c\/a\u003e\u003c\/p\u003e","brand":"Helix","offers":[{"title":"Default Title","offer_id":49311448465563,"sku":"COMPOSE Ci3 T20FM-AL MK2","price":215.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/0515\/9579\/files\/HELIX_COMPOSE_Ci3-T20FM-AL-MK2_EISA.jpg?v=1787025405","url":"https:\/\/www.integratedaudio.co\/products\/helix-ci3-t20fm-al-mk2-0-75-tweeter-pair-flexmount-4%cf%89-integrated-audio","provider":"Integrated Audio","version":"1.0","type":"link"}
