It houses two long excursion neodymium drivers in an integrated cardioid setup: a 15\" driver in a bass-reflex design facing to the front and a 12\" driver in a two chamber bandpass design radiating to the rear. The cardioid dispersion pattern resulting from this approach avoids unwanted energy behind the system that greatly reduces the reverberant field at low frequencies and provides the greatest accuracy of low frequency reproduction. The B4 subwoofer can only be used in a ground stacked setup. The B4-SUB cabinet is constructed from marine plywood, has an impact and weather resistant paint finish and a pair of handles. An M20 threaded flange in the top panel accepts the d\u0026amp;b Loudspeaker stand winder M20. The loudspeaker cabinet is also available in Special Colour (SC) options.\u003c\/p\u003e\n\u003cp\u003eThe cabinet is fitted with NLT4 F\/M connectors. All four pins of both connectors are wired in parallel. It uses the pin assignments 2+\/2–. Pins 1+\/1– are designated to TOP cabinets. Using one as the input, the second connector allows for direct connection to a second cabinet.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eComponents 15\"\/12\"\u003c\/li\u003e\n\u003cli\u003eDispersion Cardioid\u003c\/li\u003e\n\u003cli\u003eSPLmax 131 dB\u003c\/li\u003e\n\u003cli\u003eWeight 44 kg \/ 97 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): 40 - 150 Hz\u003c\/li\u003e\n\u003cli\u003eFrequency response (-5 dB 100 Hz mode): 40 - 100 Hz\u003c\/li\u003e\n\u003cli\u003eMax. sound pressure:\n\u003cul\u003e\n\u003cli\u003ewith 10D: 128 dB\u003c\/li\u003e\n\u003cli\u003ewith D20\/30D: 131 dB\u003c\/li\u003e\n\u003cli\u003ewith D40\/D80\/40D: 131 dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eCabinets per amplifier channel: 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eLoudspeaker data:\n\u003cul\u003e\n\u003cli\u003eConfiguration: Cardioid subwoofer\u003c\/li\u003e\n\u003cli\u003eNominal impedance: 6 Ω\u003c\/li\u003e\n\u003cli\u003ePower handling capacity (RMS\/peak 10 ms): 500\/2000 W\u003c\/li\u003e\n\u003cli\u003eComponents: 15\" \/ 12\" driver\u003c\/li\u003e\n\u003cli\u003eConnections: 2 x NLT4 F\/M\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eDimensions \/ weight:\n\u003cul\u003e\n\u003cli\u003eDimensions (H x W x D): 476 x 580 x 700\/ 800 mm (18.7 x 22.8 x 27.73 \/ 31.6\")\u003c\/li\u003e\n\u003cli\u003eWeight: 44 kg \/ 97 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"d\u0026b audiotechnik","offers":[{"title":"New","offer_id":53458487050605,"sku":"Z0610-002","price":0.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0975\/3224\/8429\/files\/Z0610-002.jpg?v=1781692514","url":"https:\/\/www.corporateav.ae\/products\/d-b-audiotechnik-z0610-002-b4-15-inch-12-inch-nlt4f-m-dual-passive-subwoofer","provider":"Corporate AV","version":"1.0","type":"link"}
