The cable carries a 25A maximum current rating, making it suitable for PA systems, live sound installations and powered home audio setups where longer cable runs are needed between amplifiers and passive speakers.\u003c\/p\u003e\n\u003cp\u003eDesigned for installers working on multi-room audio, distributed PA systems in commercial venues, or large outdoor events, the 100m reel length allows continuous runs without mid-cable joins. The figure 8 profile keeps the two conductors parallel and separable, so you can split them apart at termination points without cutting through additional insulation. The black PVC sheath includes a white polarity line running the length of one conductor, giving a visual reference to maintain phase consistency across multiple speaker connections.\u003c\/p\u003e\n\u003cp\u003eCCA construction offers a cost-effective alternative to pure copper for installations where budget constraints apply and cable runs are kept under typical PA lengths (under 30m per run for 8-ohm loads). The 4.0 x 8.0mm cross-section keeps the cable flexible enough to route through conduit, around corners and behind skirting without excessive stiffness. Each reel is supplied as a single continuous length, ready for cutting to the exact distances required on site.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eConductor\u003c\/td\u003e\n\u003ctd\u003eCopper Clad Aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e100m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSA\u003c\/td\u003e\n\u003ctd\u003e2.48mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrands\u003c\/td\u003e\n\u003ctd\u003e2 x (79 x 0.2mmØ)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e4.0 x 8.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSheath\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePolarity\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacked quantity\u003c\/td\u003e\n\u003ctd\u003e2 reels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent\u003c\/td\u003e\n\u003ctd\u003e25.0A max.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is CCA and how does it differ from pure copper cable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCCA (Copper Clad Aluminium) uses an aluminium core with a thin copper coating. It has higher resistance than pure copper, so it's best suited to shorter cable runs (typically under 30m for 8-ohm loads) where the resistance increase doesn't cause audible signal loss. Pure copper offers lower resistance and is preferred for longer runs or critical applications, but CCA provides a cost-effective option for budget-conscious installations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the 25A current rating mean in practice?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 25A rating indicates the maximum continuous current the cable can carry safely without overheating. In audio terms, this supports amplifiers delivering several hundred watts into typical 4-8 ohm speaker loads. Most domestic and small PA systems operate well below this threshold.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the white polarity line for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe white line runs along one of the two conductors to help identify polarity (positive\/negative) at both ends of the cable. Consistent polarity across all speakers in a system prevents phase cancellation and maintains proper sound reproduction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the two cores be separated?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The figure 8 profile allows the two conductors to be pulled apart at termination points without cutting through additional insulation, making it easier to strip and connect to speaker terminals or binding posts.\u003c\/p\u003e","brand":"AVSL","offers":[{"title":"Default Title","offer_id":45313508737291,"sku":"807.056UK","price":44.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/807056UK_LD1_632ebca3-0cbd-4546-99ed-34f695bf282a.jpg?v=1715194770","url":"https:\/\/niori.co.uk\/products\/mercury-economy-figure-8-speaker-cable-2-x-79-strand-cca-black-white-100m-reel","provider":"Niori","version":"1.0","type":"link"}
