During a 10-hour testing period, the driver's behavior is studied with numerous measurement results, allowing for the identification of weaknesses and problems that require improvement at an early design stage. The driver is subjected to up to four times its rated power. The 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 effectively.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTechnical specifications:\u003c\/b\u003e\u003cbr\u003eFeatures\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\u003eTechnical data\u003cbr\u003eModel: GZHW 30SPL\u003cbr\u003eDiameter: 300 mm \/ 12″\u003cbr\u003eMounting diameter: 315 mm \/ 12.4“\u003cbr\u003eMounting depth: 198 mm \/ 7.8“\u003cbr\u003eVoice coil: 75 mm \/ 3” copper voice coil\u003cbr\u003eCone: Reinforced paper\u003cbr\u003ePower Handling: 3000 W SPL Power\u003cbr\u003eImpedance: 2 x 2 Ohm\u003cbr\u003eSPL: 85 dB\u003cbr\u003eXmax: 45 mm \/ 1.77″\u003cbr\u003eFs: 35.4 Hz\u003cbr\u003eQts: 0.44\u003cbr\u003eVas: 15.8 L \/ 0.56 cu.ft.\u003cbr\u003e\u003cbr\u003eBox recommendation: See owners manual.\u003c\/p\u003e","brand":"Ground Zero","offers":[{"title":"Default Title","offer_id":56760113037687,"sku":"GZHW 30XSPL-D2","price":399.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/5159\/4359\/files\/GZHW-30XSPL-D2-2.jpg?v=1771443338","url":"https:\/\/hifikaupat.fi\/en\/products\/ground-zero-gzhw-30xspl-d2","provider":"Hifikaupat.fi ","version":"1.0","type":"link"}
