{"product_id":"sw12d4","title":"SW12D4 - 12-inch Dual 4-ohm Subwoofer","description":"\u003cp\u003eThe SW12D4 is a dual 4-ohm, 12-inch subwoofer built around a 1200W RMS power rating and a 3-inch high-temperature voice coil, making it a strong candidate for high-demand single or multi-amplifier setups. Its composite glass fiber cone, double-stacked ferrite magnets, and vented backplate work together to sustain clean output under sustained load. This is a woofer designed for systems where consistent performance matters as much as peak power.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1200W RMS \/ 2400W Peak\u003c\/strong\u003e — 135 oz double-stacked ferrite magnet assembly drives a 3-inch (76.5mm) black-coated high-temperature voice coil for sustained high-output performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposite glass fiber cone\u003c\/strong\u003e — 3K glass fiber and semi-pressed pulped construction balances rigidity and controlled flex for accurate low-frequency reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended pole piece with bumped backplate ventilation\u003c\/strong\u003e — channels heat away from the voice coil rapidly, reducing thermal compression during extended use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminum die-cast basket\u003c\/strong\u003e — eliminates structural resonance and maintains precise driver geometry under high excursion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMassive ridge-strengthened surround\u003c\/strong\u003e — supports extensive linear displacement across the 30–400 Hz frequency range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom copper terminals\u003c\/strong\u003e — accept wire up to 4 AWG for low-resistance connections in high-current applications.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Recoil Audio USA","offers":[{"title":"Default Title","offer_id":51059650953494,"sku":"SW12D4","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/7400\/4758\/files\/3-3_c08cffa1-275d-4925-a83b-6a40407f6dff.jpg?v=1772090051","url":"https:\/\/www.recoilaudiousa.com\/products\/sw12d4","provider":"Recoil Audio USA","version":"1.0","type":"link"}
