{"product_id":"helix-iq-w8-dvc2-high-performance-subwoofer-200mm","title":"HELIX IQ W8-DVC2 High-Performance Subwoofer 200mm","description":"This 200mm subwoofer delivers audiophile-grade bass with impressive depth and precision, thanks to its innovative Tuneable Mass System (TMS) for fine-tuning Thiele-Small parameters. A three-layer glass fibre, Mylar and honeycomb cone keeps distortion low and dynamics punchy, while the dual 2-ohm voice coils offer flexible wiring options for 1-ohm or 4-ohm setups. The high-power handling range of 300–750 watts RMS suits demanding amplifier configurations, and the aluminium die-cast frame with integrated protective grille ensures long-lasting stability. It works beautifully in both sealed and bass-reflex enclosures, making it a versatile choice for compact installations.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eType\u003c\/strong\u003e: Single chassis subwoofer\u003cbr\u003e\u003cstrong\u003eDiameter\u003c\/strong\u003e: 200 mm\u003cbr\u003e\u003cstrong\u003eImpedance\u003c\/strong\u003e: 2 x 2 Ohm\u003cbr\u003e\u003cstrong\u003ePower Handling RMS\u003c\/strong\u003e: 750 Watt\u003cbr\u003e\u003cstrong\u003ePower Handling Max\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: 43 Hz\u003cbr\u003e\u003cstrong\u003eMechanical Q Factor (Qms)\u003c\/strong\u003e: 5.30\u003cbr\u003e\u003cstrong\u003eElectrical Q Factor (Qes)\u003c\/strong\u003e: 0.49\u003cbr\u003e\u003cstrong\u003eTotal Q Factor (Qts)\u003c\/strong\u003e: 0.45\u003cbr\u003e\u003cstrong\u003eCompliance (Cms)\u003c\/strong\u003e: 123 μm\/N\u003cbr\u003e\u003cstrong\u003eEquivalent Volume (Vas)\u003c\/strong\u003e: 8.5 L\u003cbr\u003e\u003cstrong\u003eForce Factor (B*I)\u003c\/strong\u003e: 15.5 Tm\u003cbr\u003e\u003cstrong\u003eSensitivity (SPL)\u003c\/strong\u003e: 86 dB @ 2.83V\/1m\u003cbr\u003e\u003cstrong\u003eCone Area (Sd)\u003c\/strong\u003e: 222 cm²\u003cbr\u003e\u003cstrong\u003eMoving Mass (Mms)\u003c\/strong\u003e: 115 g\u003cbr\u003e\u003cstrong\u003eCone Material\u003c\/strong\u003e: Glass fibre, Mylar, honeycomb\u003cbr\u003e\u003cstrong\u003eMechanical Resistance (Rms)\u003c\/strong\u003e: 5.8 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: 226 mm\u003cbr\u003e\u003cstrong\u003eMounting Diameter\u003c\/strong\u003e: 183 mm\u003cbr\u003e\u003cstrong\u003eMounting Depth\u003c\/strong\u003e: 114.5 mm\u003cbr\u003e\u003cstrong\u003eFrame Material\u003c\/strong\u003e: Aluminium die-cast\u003cbr\u003e\u003cstrong\u003eProtective Grille\u003c\/strong\u003e: Integrated\u003cbr\u003e\u003cstrong\u003eTuneable Mass System (TMS)\u003c\/strong\u003e: Yes, configurable with included weights\u003cbr\u003e\u003cstrong\u003eRecommended Sealed Enclosure Volume\u003c\/strong\u003e: 6–35 L\u003cbr\u003e\u003cstrong\u003eRecommended Bass-Reflex Enclosure Volume\u003c\/strong\u003e: 13–38 L\u003cbr\u003e","brand":"HELIX","offers":[{"title":"Default Title","offer_id":53773394772305,"sku":"Q430802","price":349.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/2772\/5905\/files\/HELIX_IMPACT_IQ-W8-DVC2_Pers_29-01-2025_ad1ae26d-d3f7-4f46-b48c-3c7c67e535d4.jpg?v=1778715039","url":"https:\/\/shoponyxac.co.uk\/products\/helix-iq-w8-dvc2-high-performance-subwoofer-200mm","provider":"Onyx Auto Care","version":"1.0","type":"link"}
