Delivering powerful bass and neutral midrange, it pairs perfectly with the S 1T tweeter for a complete sound system. The specially shaped rubber surround increases effective cone area and maximum excursion, while the basket's ventilation openings optimise voice coil cooling. Gold-plated terminals ensure a reliable connection, and the rubber magnet cover with HELIX branding adds a polished finish.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePower Handling RMS \/ Max\u003c\/strong\u003e: 100 \/ 200 W\u003cbr\u003e\u003cstrong\u003eImpedance\u003c\/strong\u003e: 4 Ohm\u003cbr\u003e\u003cstrong\u003eDC Resistance (Re)\u003c\/strong\u003e: 3.4 Ohm\u003cbr\u003e\u003cstrong\u003eFrequency Range\u003c\/strong\u003e: 45 Hz - 4,000 Hz\u003cbr\u003e\u003cstrong\u003eResonant Frequency (Fs)\u003c\/strong\u003e: 67 Hz\u003cbr\u003e\u003cstrong\u003eMechanical Q (Qms)\u003c\/strong\u003e: 3.87\u003cbr\u003e\u003cstrong\u003eElectrical Q (Qes)\u003c\/strong\u003e: 0.96\u003cbr\u003e\u003cstrong\u003eTotal Q (Qts)\u003c\/strong\u003e: 0.77\u003cbr\u003e\u003cstrong\u003eSensitivity (1W\/1m)\u003c\/strong\u003e: 90 dB\u003cbr\u003e\u003cstrong\u003eVoice Coil Diameter\u003c\/strong\u003e: 25 mm\u003cbr\u003e\u003cstrong\u003eMax Linear Excursion (Xmax)\u003c\/strong\u003e: +\/- 3 mm\u003cbr\u003e\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 165 mm\u003cbr\u003e\u003cstrong\u003eMounting Diameter\u003c\/strong\u003e: 143 mm\u003cbr\u003e\u003cstrong\u003eMounting Depth\u003c\/strong\u003e: 65 mm\u003cbr\u003e\u003cstrong\u003eCone Material\u003c\/strong\u003e: Basalt Fibre-Paper Compound\u003cbr\u003e\u003cstrong\u003eRecommended Sealed Enclosure Volume\u003c\/strong\u003e: 9 L\u003cbr\u003e\u003cstrong\u003eLower Cut-off Frequency (-3dB) Sealed\u003c\/strong\u003e: 75 Hz\u003cbr\u003e","brand":"HELIX","offers":[{"title":"Default Title","offer_id":53773133480273,"sku":"S721600","price":129.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/2772\/5905\/files\/HELIX_S-6B_Pers_1280x1280px_14-01-2021_b33bc2b9-6a78-4bea-89c4-96c6e7ba39f5.jpg?v=1778711332","url":"https:\/\/shoponyxac.co.uk\/products\/helix-s-6b-165mm-mid-bass-speaker-100w-rms-4-ohm","provider":"Onyx Auto Care","version":"1.0","type":"link"}
