Rated at 400W RMS with an 800W peak, it delivers controlled low-end reproduction down to 32 Hz through a combination of high-flux ferrite motor design and active thermal management. This is a purpose-built driver for builds that demand reliable, sustained performance in a smaller enclosure footprint.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4-layer high-temperature copper voice coil\u003c\/strong\u003e sustains peak output over extended listening sessions without thermal rolloff.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-flux ferrite motor\u003c\/strong\u003e generates the magnetic force needed for accurate, authoritative bass reproduction across the full 32–600 Hz range.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePolycarbonate spider suspension\u003c\/strong\u003e provides consistent linear excursion and improved responsiveness at all drive levels.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdvanced airflow cooling system\u003c\/strong\u003e actively manages heat buildup, protecting the voice coil during high-demand use.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIMPP cone material\u003c\/strong\u003e balances rigidity and low mass for accurate transient response.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual 4-ohm voice coil\u003c\/strong\u003e allows flexible wiring configurations — 2-ohm parallel or 8-ohm series — to match a range of amplifier outputs.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Recoil Audio USA","offers":[{"title":"Default Title","offer_id":51059598885142,"sku":"PW8D4","price":90.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/7400\/4758\/files\/PW8D4-1.jpg?v=1772086717","url":"https:\/\/www.recoilaudiousa.com\/products\/pw8d4","provider":"Recoil Audio USA","version":"1.0","type":"link"}
