{"product_id":"amina-amina-backbox-cv200","title":"Amina Backbox CV200","description":"Application:\u003cbr\u003e\r\nThe BackboxCV200 is an easy to install, sound proofing backbox for the Amina\r\nEvolution Series S200 narrow format speaker models. For use in plasterboard cavity\r\nwalls (drywalls) and ceilings, the BackboxCV200 creates a sealed enclosure around the\r\nback of the speaker utilising a specially designed composite sound proofing layer. The\r\nBackboxCV200 is recommended for multispeaker installations where the cavity loading\r\nthe backbox provides will ensure consistent sound quality from all speaker locations.\u003cbr\u003e\u003cbr\u003e\r\n\r\n\r\nInstallation:\u003cbr\u003e\r\nThe BackboxCV200 is designed to be retrofitted into the plasterboard wall or ceiling.\r\nImportantly it is fixed to the plasterboard only (not surrounding studwork) which\r\nreduces potential energy transfer to the wall\/ceiling joists. Our detailed installation\r\nguide provides information on how to achieve the correct speaker face alignment for\r\ndifferent types of plaster finishes and plasterboard thicknesses. Optional alignment\r\nshims are also available.\u003cbr\u003e\u003cbr\u003e\r\n\r\nSound Proofing Characteristic:\u003cbr\u003e\r\nThe graph below shows the sound pressure level attenuation of an Amina AIW Evolution\r\nSeries speaker’s rearward output when installed in a BackboxCV200. Over the 150Hz\r\n– 5KHz range the rear firing airborne sound pressure is reduced on average by 21dB.\r\nIt is recommended that additional sound proofing steps are taken if your speakers are\r\ninstalled in a wall or ceiling where bedrooms or other occupied rooms are directly\r\nadjacent. The BackboxCV200 cannot stop mechanically induced noise transmission\r\ninherent in certain building structures.\u003cbr\u003e\u003cbr\u003e\r\n\r\nTechnical Specifications:-\u003cbr\u003e\r\nDimensions:500mm x 206mm x 71.5mm\u003cbr\u003e\r\nPlasterboard cut-out required:455mm x 205mm\u003cbr\u003e\r\nProduct weight: 1.2Kg (2.64lbs)\u003cbr\u003e\r\nSpeaker cable entry: Rubber grommet(can be replaced by M20 gland)\u003cbr\u003e\r\nSpeaker fixing: Use 4x self tapping flangehead screws(supplied)\u003cbr\u003e\r\nWall fixing: Use 8x self tapping drywall screws (supplied)\u003cbr\u003e\r\nMinimum cavity: depth 75mm (3”)\u003cbr\u003e\r\nSound pressure reduction: -21dB on average over 150Hz - 5kHz range","brand":"Amina","offers":[{"title":"Amina Backbox CV200","offer_id":57851227504972,"sku":"AMINABACKBOXCV200","price":80.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/amina_back_20Box.jpg?v=1781883117","url":"https:\/\/www.stoneaudio.co.uk\/products\/amina-amina-backbox-cv200","provider":"Stone Audio","version":"1.0","type":"link"}
