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\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","offers":[{"title":"Default Title","offer_id":52595534528795,"sku":"SW12D4","price":300.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/2110\/9531\/files\/image_16a72577-70ba-4caf-af16-8aa2c400ccf8.jpg?v=1784219000","url":"https:\/\/true49.com\/products\/echo-max-series-12-dual-4-ohm-subwoofer-1-200-watts-rms-power-handling-sw12d4","provider":"True49 Technologies Ltd.","version":"1.0","type":"link"}
