When you look closer, you will see other details that help make this driver an excellent performer. The reinforced paper cone with a super strong dust cap is double stitched to the surround. The coil cooling takes place through a large tunnel in the pole piece and with cooling vents in the frame. The coil is 3″ in diameter and wrapped with OFC wire. Push-type terminals hold the cables securely, and the Polycot spider can handle a large X-max.\u003cbr\u003e\u003cbr\u003eYou cannot see all the things that are important, and the most important of the unseen are Klippel optimizations. Using the Klippel device, all parts of the subwoofer can be monitored during a 10+ hour torture test. During the test, the speaker's power handling capability is truly tested, delivering up to 4 times more than the driver was designed to handle. The purpose of this torture is to identify the weakest points of the prototypes and strengthen them for the final product.\u003c\/p\u003e\n\u003ch3\u003eTechnical data\u003c\/h3\u003e\n\u003cp\u003e- 12″ subwoofer\u003cbr\u003e - 3″ copper voice coil\u003cbr\u003e- Klippel optimized\u003cbr\u003e- Aluminium cast basket\u003cbr\u003e- Reinforced paper cone\u003cbr\u003e- High-roll sandwich surround\u003cbr\u003e- 2x 2 ohm voice coils\u003cbr\u003e- Power handling 1000 W RMS, 1500 W Peak\u003cbr\u003e- Sealed enclosure 19-40 liters\u003cbr\u003e- Ported enclosure 35-50 liters tuned to 32-37 Hz\u003cbr\u003e- Recommended amplifier power 800-1500 W RMS\u003cbr\u003e- Mounting depth: 150 mm\u003cbr\u003e- Mounting hole diameter: 281 mm\u003cbr\u003e- Motor diameter: 175 mm\u003cbr\u003e\u003cbr\u003eThiele-Small parameters:\u003cbr\u003e\u003cbr\u003eRe: 3.84 ohm\u003cbr\u003eFs: 40.5 Hz\u003cbr\u003eQms: 4.984\u003cbr\u003eQes 0.593\u003cbr\u003eQts: 0.530\u003cbr\u003eVas: 17.7 liters\u003cbr\u003eLe: 3.112 mH\u003cbr\u003eMms: 256.8 gr\u003cbr\u003eX-max: 50 mm\u003cbr\u003eSPL: 86\u003cbr\u003eBl: 20.62 TeslaM.\u003c\/p\u003e","brand":"Ground Zero","offers":[{"title":"Default Title","offer_id":53651551191381,"sku":"GZRW 300SPL","price":202.26,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1356\/2245\/files\/Ground-Zero-GZRW-300SPL.jpg?v=1776128885","url":"https:\/\/www.autogarsas.lt\/en\/products\/ground-zero-gzrw-300spl","provider":"AUTOGARSAS.LT","version":"1.0","type":"link"}
