Not surprisingly, as it had excellent sound quality for its price range.\u003cbr\u003e\n\u003cbr\u003e\nThis new model features a new subwoofer that has been optimized using a Klippel device. The speaker has a smooth impedance response, good sensitivity, and good power handling. These characteristics provide good sound quality and plenty of bass with very modest amplifier power. \u003cbr\u003e\n\u003cbr\u003e\nA new, better speaker also deserves a better enclosure. The previous enclosure was so good that it was difficult to improve it. The solution was to invent a new type of port. This enclosure uses an EFP (Enhanced Flow Port) port. It has a cross-section like an aero port. This provides significantly better airflow without side effects. More air through the port = more bass! Despite the improved airflow in the same size enclosure, the tuning frequency remains the same as before. And it provides a very smooth bass response across the 20-60 Hz frequency band. The port size corresponds to a 3.5″ aero port. So it is more than sufficient for the required amplifier power for this subwoofer. \u003cbr\u003e\n\u003cbr\u003e\nIf you are looking for a box that provides good sound quality and plenty of bass with medium-sized amplifiers, it's here.\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n- 12″ subwoofer\u003cbr\u003e\n- EFP ( Enhanced Flow Port ) ported box\u003cbr\u003e\n- 350 W RMS\u003cbr\u003e\n- enclosure volume 37 liters\u003cbr\u003e\n- very smooth response 20-60 Hz\u003cbr\u003e\n- measurements WxHxD: 46x37x31\/40.","brand":"Ground Zero","offers":[{"title":"Default Title","offer_id":53651542901077,"sku":"GZIB 300XBR","price":174.63,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1356\/2245\/files\/Ground-Zero-GZIB-300XBR.jpg?v=1776128427","url":"https:\/\/www.autogarsas.lt\/en\/products\/ground-zero-gzib-300xbr","provider":"AUTOGARSAS.LT","version":"1.0","type":"link"}
