Its construction features a Kevlar-reinforced pulp cone, known for its rigidity and lightness, paired with a durable HAMRS Santoprene rubber surround. This combination allows for extensive excursion and contributes to the subwoofer's ability to produce deep, impactful low frequencies.\n\nWith a substantial power handling capacity of 300-1,000 watts RMS (with 500 watts per coil) and a peak power rating of 3,000 watts, the SWR-12D2 is designed to be driven by powerful amplifiers. The dual 2-ohm voice coils offer versatile wiring options, enabling users to configure the subwoofer for optimal impedance matching with their amplifier, whether wired in series or parallel. This flexibility ensures that users can extract maximum performance as their audio systems evolve.\n\nThe subwoofer's performance characteristics include a wide frequency response of 24-200 Hz, capturing everything from deep sub-bass to mid-bass punch. Its sensitivity rating is 84.7 dB, indicating its efficiency in converting power into sound. The SWR-12D2 is designed to perform well in both sealed and ported enclosures, providing distinct sonic characteristics depending on the enclosure type and tuning. Specific enclosure volume recommendations are 0.75-1.00 cubic feet for sealed boxes and 1.25-1.50 cubic feet for ported boxes.","brand":"Alpine","offers":[{"title":"Default Title","offer_id":52686866743608,"sku":"SWR-12D2","price":319.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660673780.jpg?v=1784877706","url":"https:\/\/store.motormia.co\/products\/12-inch-dual-2-ohm-voice-coil-subwoofer-1","provider":"MOTORMIA","version":"1.0","type":"link"}
