Inquisitive minds will revel in the endless system design possibilities these precision bass drivers afford.\u003cbr\u003e\u003cbr\u003eOriginally dubbed The Beast, 9900 series subwoofers first hit the market in the early 2000s. After a brief hiatus, they are back and now more powerful than ever. The latest version was developed in response to the recent explosion of ultra-low frequency music. These subwoofers were engineered for long-term power handling, precision, and high excursion. They have been optimized for the 1500 – 2500W power band, with the ability to handle bursts up to 10,000W. One glance at the 9900 motor tells you why we call it the beast. It features a 3-inch magnet slug, over 10″ OD, and weighs 70 pounds (motor only). A traditionally narrow DD magnet gap drives the 4″ flat wound aluminum voice coil to a top-end excursion of over 3 inches while keeping enough windings in the gap for 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 0.5 ohm voice coil\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":53651510624597,"sku":"DD9921-D0.5","price":2946.52,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1356\/2245\/files\/DD-Audio-9921-D0_5.png?v=1776125647","url":"https:\/\/www.autogarsas.lt\/en\/products\/dd-audio-9921-d0-5","provider":"AUTOGARSAS.LT","version":"1.0","type":"link"}
