In a 10-hour test, the driver's behavior is examined using numerous measurement results, and thus weak points and problems that require improvement are identified early in the design process. The driver is subjected to up to four times the power it can handle. The end result is a driver with a very flat impedance response, meaning it accepts power well at all frequencies, has good sensitivity, and can handle power well.\u003cbr\u003e\u003cbr\u003e \u003cb\u003eSpecifications:\u003c\/b\u003e\u003cbr\u003e Features\u003cbr\u003e - High power 12\" SPL subwoofer \u003cbr\u003e- Klippel® optimized\u003cbr\u003e - Efficient triple magnet\u003cbr\u003e - Massive aluminum cast basket\u003cbr\u003e - Reinforced paper cone\u003cbr\u003e - 3” copper voice coil\u003cbr\u003e - High-Roll sandwich surround\u003cbr\u003e - Double spider\u003cbr\u003e\u003cbr\u003e Technical data\u003cbr\u003e Model: GZHW 30SPL\u003cbr\u003e Diameter: 300 mm \/ 12″\u003cbr\u003e Mounting diameter: 315 mm \/ 12.4“\u003cbr\u003e Mounting depth: 198 mm \/ 7.8“\u003cbr\u003e Voice coil: 75 mm \/ 3” copper voice coil\u003cbr\u003e Cone: Reinforced paper\u003cbr\u003e Power Handling: 3000 W SPL Power\u003cbr\u003e Impedance: 2 x 1 Ohm\u003cbr\u003e SPL: 85 dB\u003cbr\u003e Xmax: 45 mm \/ 1.77″\u003cbr\u003e Fs: 35.4 Hz\u003cbr\u003e Qts: 0.44\u003cbr\u003e Left: 15.8 L \/ 0.56 cu.ft.\u003cbr\u003e\u003cbr\u003e Box recommendations: See owners manual.\u003c\/b\u003e","brand":"Ground Zero","offers":[{"title":"Default Title","offer_id":56760106090871,"sku":"GZHW 30XSPL-D1","price":399.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/5159\/4359\/files\/GZHW-30XSPL-D1-2_b365799b-604f-48b4-bbf4-1d4d3040761b.jpg?v=1771443304","url":"https:\/\/hifikaupat.fi\/en\/products\/ground-zero-gzhw-30xspl-d1","provider":"Hifikaupat.fi ","version":"1.0","type":"link"}
