The cabinet houses a single long excursion 21\" driver in a bass-reflex design. The large, specially shaped reflex port enables the 21S-SUB to achieve high Sound Pressure Levels from a cabinet with a small footprint. When operated in INFRA mode, the 21S-SUB can be used to complement other d\u0026amp;b subwoofers by extending the frequency response of the system down to 33Hz. The 21S-SUB can be ground stacked or flown in either orientation. It can be flown individually or in a cluster of two cabinets. The enclosure is constructed from marine plywood with an impact resistant black paint finish. The front of the loudspeaker cabinet is protected by a rigid metal grill backed by an acoustically transparent foam. The top, bottom and rear panels each incorporate a pair of M10 threaded inserts for attaching d\u0026amp;b rigging hardware.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eComponents: 2 x 12\"\/1.4\"\u003c\/li\u003e\n\u003cli\u003eDispersion: 110° x 45°\u003c\/li\u003e\n\u003cli\u003eSPLmax: 137 dB\u003c\/li\u003e\n\u003cli\u003eWeight: 33 kg \/ 73 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSystem data:\n\u003cul\u003e\n\u003cli\u003eFrequency response (-5 dB standard): 35Hz – 105Hz\u003c\/li\u003e\n\u003cli\u003eFrequency response (-5 dB INFRA mode): 33Hz – 85Hz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eMax. sound pressure:\n\u003cul\u003e\n\u003cli\u003eD20\/30D amplifier: 134dB\u003c\/li\u003e\n\u003cli\u003eD80 amplifier: 135dB\u003c\/li\u003e\n\u003cli\u003eCabinets per amplifier channel: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eLoudspeaker data:\n\u003cul\u003e\n\u003cli\u003eConfiguration: Installation-specific high-performance subwoofer with a compact footprint\u003c\/li\u003e\n\u003cli\u003eNominal impedance: 4 ohm\u003c\/li\u003e\n\u003cli\u003ePower handling capacity (RMS\/peak 10ms): 650\/2600W\u003c\/li\u003e\n\u003cli\u003eComponents: 21″ driver with neodymium magnet\u003c\/li\u003e\n\u003cli\u003eConnections: Faston connector type 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eDimensions \/ Weight (H x W x D) (Approx.):\n\u003cul\u003e\n\u003cli\u003eHeight: 43-5\/16″\u003c\/li\u003e\n\u003cli\u003eWidth: 22-13\/16″\u003c\/li\u003e\n\u003cli\u003eDepth: 20-11\/16″\u003c\/li\u003e\n\u003cli\u003eWeight: 119 lb. \/ 54 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"d\u0026b audiotechnik","offers":[{"title":"New","offer_id":53458490753389,"sku":"Z1613-000","price":0.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0975\/3224\/8429\/files\/Z1613-000.jpg?v=1781692519","url":"https:\/\/www.corporateav.ae\/products\/d-b-audiotechnik-z1613-000-21s-sub-21-inch-passive-subwoofer","provider":"Corporate AV","version":"1.0","type":"link"}
