Inquisitive minds will revel in the endless system design possibilities offered by these precision low-frequency transducers.\u003cbr\u003e\u003cbr\u003eOriginally dubbed \"The Beast,\" the 9900 series subwoofers first hit the market in the early 2000s. After a brief hiatus, they are back and more powerful than ever. The latest version was developed in response to the recent explosion of ultra-low frequency music. These subwoofers were designed for long-term power handling, precision, and high excursion. They have been optimized for a power band of 1500 – 2500 W, with the ability to withstand bursts of up to 10,000 W. One look at the 9900 motor shows why we call it a beast. It features a 3-inch magnet stack, over 10″ OD, and weighs 70 pounds (motor only). The traditionally narrow DD magnet gap drives a 4″ flat-wound aluminum voice coil to an X-max exceeding 3 inches, maintaining enough windings in the gap to ensure power and control.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cp\u003e- 21″ subwoofer\u003cbr\u003e- cast frame\u003cbr\u003e- 2 x 1 ohm voicecoil\u003cbr\u003e- magnet weight 31.7 kg\u003cbr\u003e- 4″ voice coil diameter\u003cbr\u003e- driver displacement: 13 liters\u003cbr\u003e- recommended ported enclosure 170-200 liters (NET)\u003cbr\u003e- power handling 2500 W RMS\u003cbr\u003e- peak power handling 10,000 watts\u003cbr\u003e- x-max: +- 22 mm\u003cbr\u003e- xmech: 92 mm\u003cbr\u003e- qts: 0.46\u003cbr\u003e- Fs: 33.65 Hz\u003cbr\u003e- Vas: 161.54 liters.\u003c\/p\u003e","brand":"DD Audio","offers":[{"title":"Default Title","offer_id":53651510657365,"sku":"DD9921-D1","price":2899.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1356\/2245\/files\/DD-Audio-9921-D1.png?v=1776125666","url":"https:\/\/www.autogarsas.lt\/en\/products\/dd-audio-9921-d1","provider":"AUTOGARSAS.LT","version":"1.0","type":"link"}
