To maximize the performance of this subwoofer we highly recommend using a dedicated enclosure. Inside the included datasheet are specifications and two recommended enclosures: one is a sealed enclosure; the other is a ported design. Both types of enclosures will give excellent sound quality and low-frequency extension. The sealed enclosure is a better choice if space is extremely tight, while the ported enclosure will produce 3dB more output with the same power if there is extra space to work with.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003e- Non-pressed paper cone with long throw foam surround.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Dual 44.7 Oz ferrite magnet, 2”\/50 mm voice coil.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Steel basket with anti-resonant painting.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003e- Nominal Impedance: 4+4 Ohm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Nominal Power Handling: 300 W\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Peak Power: 600 W\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Frequency Response: 33 Hz ~ 400 Hz\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e- Sensitivity: 87.4 dB 2.83v\/1m\u003c\/span\u003e\u003c\/p\u003e","brand":"ESB Audio","offers":[{"title":"Default Title","offer_id":53513722659105,"sku":"310D4","price":239.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/1145\/9873\/files\/310D_1_c35bae37-f9c5-479c-ab12-d16b04b16028.jpg?v=1789621062","url":"https:\/\/www.shopalumapro.com\/products\/esb-3-10d4","provider":"ShopAlumapro.com","version":"1.0","type":"link"}
