{"product_id":"helix-ik-es10-1-dvc2-mk2-downfire-subwoofer-250mm-1","title":"HELIX IK ES10.1-DVC2 MK2 Downfire Subwoofer 250mm","description":"The HELIX IK ES10.1-DVC2 MK2 is a downfire subwoofer that delivers powerful bass from an ultra-slim bass reflex enclosure, perfect for tight spaces like a double boot floor. Its clever downfire design uses the vehicle floor as an acoustic reflector for even bass distribution, while the 250mm chassis with a stiff sandwich paper cone ensures deep, dynamic sound. The pluggable terminal offers both screw and MOLEX connections for flexible installation, and the dual voice coil allows impedance switching between 1 x 1 ohm, 1 x 4 ohm, or 2 x 2 ohm. This MK2 version is ISM-ready, meaning you can swap the passive terminal for an optional IMPACT Subwoofer Module to turn it into an active subwoofer. The robust needle-felt casing with an embroidered HELIX logo and Velcro feet keeps it securely in place, even during intense bass playback.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eType\u003c\/strong\u003e: Downfire enclosure subwoofer\u003cbr\u003e\u003cstrong\u003eChassis Diameter\u003c\/strong\u003e: 250 mm\u003cbr\u003e\u003cstrong\u003eImpedance\u003c\/strong\u003e: 2 x 2 ohm \/ 1 x 4 ohm \/ 1 x 1 ohm (selectable)\u003cbr\u003e\u003cstrong\u003eRMS Power Handling\u003c\/strong\u003e: 300 W\u003cbr\u003e\u003cstrong\u003eRecommended Amplifier Power (RMS)\u003c\/strong\u003e: 150 - 300 W\u003cbr\u003e\u003cstrong\u003eMax Linear Cone Excursion (Xlin)\u003c\/strong\u003e: +\/- 6 mm\u003cbr\u003e\u003cstrong\u003eMax Mechanical Cone Excursion (Xmax)\u003c\/strong\u003e: +\/- 15 mm\u003cbr\u003e\u003cstrong\u003eTuning Frequency (Fb)\u003c\/strong\u003e: 37 Hz\u003cbr\u003e\u003cstrong\u003eSensitivity (1W\/1m)\u003c\/strong\u003e: 88 dB\u003cbr\u003e\u003cstrong\u003eEnclosure Material\u003c\/strong\u003e: MDF with needle-felt covering\u003cbr\u003e\u003cstrong\u003eDimensions (H x W x D)\u003c\/strong\u003e: 135 x 725 x 350 mm\u003cbr\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e: Approx. 12 kg\u003cbr\u003e\u003cstrong\u003eCompatible Amplifier Module\u003c\/strong\u003e: HELIX IMPACT ISM 400.2DSP\u003cbr\u003e","brand":"HELIX","offers":[{"title":"Default Title","offer_id":53773359841617,"sku":"K331021","price":249.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/2772\/5905\/files\/HELIX-IMPACT-IK-ES10-1-DVC2-MK2_1204f904-4533-453b-bb2b-75a0c8545930.jpg?v=1778714560","url":"https:\/\/shoponyxac.co.uk\/products\/helix-ik-es10-1-dvc2-mk2-downfire-subwoofer-250mm-1","provider":"Onyx Auto Care","version":"1.0","type":"link"}
