{"product_id":"cable-altavoz-rojo-negro-2x1-5mm-cca","title":"Red and Black Speaker Cable 2 x 1.5 mm² CCA, from 10 to 100 m","description":"\u003cp\u003eTwo-conductor speaker cable of 1.5 mm² each, one red and one black so you do not lose the polarity when connecting them. The conductor is \u003cstrong\u003eCCA\u003c\/strong\u003e, copper-clad aluminium, and the sheath is PVC. It is sold on reels of \u003cstrong\u003e10, 25, 50 and 100 metres\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt is worth knowing what CCA implies, because it is what sets this cable apart from a pure copper one. Aluminium is a poorer conductor: \u003cstrong\u003ethe resistance per metre is around 50 % higher\u003c\/strong\u003e than that of OFC copper of the same cross-section. In practice this means slightly less level and, above all, a lower damping factor, which is what controls the bass.\u003c\/p\u003e\n\u003cp\u003eFrom this comes a useful rule. To keep the cable resistance from exceeding 5 % of the speaker impedance, which is the usual criterion, with an 8 ohm speaker \u003cstrong\u003eit is best not to exceed about 11 metres per speaker\u003c\/strong\u003e with this cross-section in CCA. With a 4 ohm one, about 5 or 6 metres. The long reels make sense for splitting the cable between several speakers, not for a single 50 metre run.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis product is not approved for permanent installation in buildings\u003c\/strong\u003e: it has no reaction-to-fire classification under the EN 50575 standard of the Construction Products Regulation, so it is intended for portable speakers, temporary installations and wiring inside furniture or enclosures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTwo 1.5 mm² conductors, in red and black to mark the polarity\u003c\/li\u003e\n\u003cli\u003eCCA conductor: copper-clad aluminium, 2 × 30 strands of 0.25 mm\u003c\/li\u003e\n\u003cli\u003eAround 50 % more resistance per metre than OFC copper\u003c\/li\u003e\n\u003cli\u003eRecommended up to about 11 m per speaker at 8 ohms\u003c\/li\u003e\n\u003cli\u003ePVC sheath\u003c\/li\u003e\n\u003cli\u003eReels of 10, 25, 50 and 100 m\u003c\/li\u003e\n\u003cli\u003eNot suitable for permanent installation in buildings (no EN 50575 classification)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable class=\"specs\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"table-data\"\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eTwo-conductor speaker cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"table-data\"\u003e\n\u003ctd\u003eCross-section\u003c\/td\u003e\n\u003ctd\u003e2 × 1.5 mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"table-data\"\u003e\n\u003ctd\u003eConductor\u003c\/td\u003e\n\u003ctd\u003eCCA (copper-clad aluminium)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"table-data\"\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003e2 × 30 strands of 0.25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"table-data\"\u003e\n\u003ctd\u003ePolarity\u003c\/td\u003e\n\u003ctd\u003eRed and black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"table-data\"\u003e\n\u003ctd\u003eOuter material\u003c\/td\u003e\n\u003ctd\u003ePVC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"table-data\"\u003e\n\u003ctd\u003eRecommended length\u003c\/td\u003e\n\u003ctd\u003eUp to about 11 m per speaker at 8 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"table-data\"\u003e\n\u003ctd\u003eFire classification\u003c\/td\u003e\n\u003ctd\u003eNo EN 50575 classification; not suitable for fixed installation in buildings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"table-data\"\u003e\n\u003ctd\u003eLengths\u003c\/td\u003e\n\u003ctd\u003eReels of 10, 25, 50 and 100 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"TiendaCables","offers":[{"title":"Default Title","offer_id":49988846813450,"sku":"TCALT1010","price":3.76,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/1692\/1866\/files\/2_b165ce7d-f08e-4ef5-bb7b-cb40e0031cbd.png?v=1733138270","url":"https:\/\/www.tiendacables.com\/en\/products\/cable-altavoz-rojo-negro-2x1-5mm-cca","provider":"TiendaCables","version":"1.0","type":"link"}
