A three-layer fibreglass-Mylar honeycomb cone ensures minimal distortion and lightning-fast impulse response, even during demanding passages. The dual 2-ohm voice coil offers flexible wiring options (1 ohm or 4 ohm total) to match almost any amplifier setup, while the die-cast aluminium basket with integrated grille guarantees long-term reliability. Whether you prefer a sealed or bass-reflex enclosure, this 250mm subwoofer adapts beautifully to your vehicle's acoustics.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eType\u003c\/strong\u003e: Single chassis subwoofer\u003cbr\u003e\u003cstrong\u003eSize\u003c\/strong\u003e: 250 mm (10 inch)\u003cbr\u003e\u003cstrong\u003eImpedance\u003c\/strong\u003e: 2 x 2 Ohm\u003cbr\u003e\u003cstrong\u003eRMS Power Handling\u003c\/strong\u003e: 750 Watt\u003cbr\u003e\u003cstrong\u003eMax Power Handling\u003c\/strong\u003e: 1500 Watt\u003cbr\u003e\u003cstrong\u003eRecommended Amplifier Power\u003c\/strong\u003e: From 300 Watt RMS\u003cbr\u003e\u003cstrong\u003eDC Resistance (Re)\u003c\/strong\u003e: 2 x 1.9 Ohm\u003cbr\u003e\u003cstrong\u003eResonance Frequency (Fs)\u003c\/strong\u003e: 38 Hz\u003cbr\u003e\u003cstrong\u003eMechanical Q Factor (Qms)\u003c\/strong\u003e: 6.00\u003cbr\u003e\u003cstrong\u003eElectrical Q Factor (Qes)\u003c\/strong\u003e: 0.46\u003cbr\u003e\u003cstrong\u003eTotal Q Factor (Qts)\u003c\/strong\u003e: 0.43\u003cbr\u003e\u003cstrong\u003eCompliance (Cms)\u003c\/strong\u003e: 115 μm\/N\u003cbr\u003e\u003cstrong\u003eEquivalent Volume (Vas)\u003c\/strong\u003e: 21 L\u003cbr\u003e\u003cstrong\u003eForce Factor (B*l)\u003c\/strong\u003e: 17.8 Tm\u003cbr\u003e\u003cstrong\u003eSensitivity (SPL)\u003c\/strong\u003e: 89 dB @ 2.83V \/ 1m\u003cbr\u003e\u003cstrong\u003eCone Area (Sd)\u003c\/strong\u003e: 363 cm²\u003cbr\u003e\u003cstrong\u003eMoving Mass (Mms)\u003c\/strong\u003e: 158 g\u003cbr\u003e\u003cstrong\u003eCone Material\u003c\/strong\u003e: 3-layer fibreglass-Mylar honeycomb\u003cbr\u003e\u003cstrong\u003eMechanical Resistance (Rms)\u003c\/strong\u003e: 6.2 kg\/s\u003cbr\u003e\u003cstrong\u003eVoice Coil Diameter\u003c\/strong\u003e: 63 mm\u003cbr\u003e\u003cstrong\u003eVoice Coil Winding Width\u003c\/strong\u003e: 32 mm\u003cbr\u003e\u003cstrong\u003eMax Linear Excursion (Xmax)\u003c\/strong\u003e: +\/- 12 mm\u003cbr\u003e\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 275 mm\u003cbr\u003e\u003cstrong\u003eMounting Diameter\u003c\/strong\u003e: 234.6 mm\u003cbr\u003e\u003cstrong\u003eMounting Depth\u003c\/strong\u003e: 134.5 mm\u003cbr\u003e\u003cstrong\u003eRecommended Sealed Enclosure Volume\u003c\/strong\u003e: 13 L\u003cbr\u003e\u003cstrong\u003eRecommended Bass-Reflex Enclosure Volume\u003c\/strong\u003e: 27 L\u003cbr\u003e\u003cstrong\u003eBass-Reflex Port Diameter\u003c\/strong\u003e: 80 mm\u003cbr\u003e\u003cstrong\u003eBass-Reflex Port Area\u003c\/strong\u003e: 50 cm²\u003cbr\u003e\u003cstrong\u003eBass-Reflex Port Length\u003c\/strong\u003e: 40 cm\u003cbr\u003e\u003cstrong\u003eTuneable Mass System (TMS)\u003c\/strong\u003e: Yes, with 3 tuning masses included\u003cbr\u003e\u003cstrong\u003eBasket Material\u003c\/strong\u003e: Die-cast aluminium\u003cbr\u003e\u003cstrong\u003eProtective Grille\u003c\/strong\u003e: Integrated\u003cbr\u003e","brand":"HELIX","offers":[{"title":"Default Title","offer_id":53773395099985,"sku":"Q431003","price":399.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/2772\/5905\/files\/HELIX_IMPACT_IQ-W10-DVC2_Pers_29-01-2025_b96075af-7220-4698-b634-171e1c5511c5.jpg?v=1778715053","url":"https:\/\/shoponyxac.co.uk\/products\/helix-iq-w10-dvc2-high-performance-subwoofer-250mm","provider":"Onyx Auto Care","version":"1.0","type":"link"}
