The cable is rated to 15A maximum current and supplied on a 100m reel with a clear PVC sheath and red polarity stripe running along one conductor to simplify wiring.\u003c\/p\u003e\n\u003cp\u003eDesigned for medium-power distributed audio in retail, hospitality, small commercial installations and domestic multi-room setups, the cable suits passive speaker runs where conductor cost is a primary concern and audiophile-grade oxygen-free copper is not required. The figure-8 profile measures 3.8mm x 7.6mm overall, making it narrow enough to route through standard cable trunking, under carpets or along skirting board clips. The 100m reel length supports multiple speaker drops from a single spool without joins.\u003c\/p\u003e\n\u003cp\u003eCopper clad aluminium conductors provide lighter weight and lower material cost than solid copper cable, trading some conductivity for economy on longer runs where voltage drop is not critical. The transparent sheath allows visual confirmation of conductor condition during installation and the red polarity line ensures consistent phase across all speakers in a multi-zone system. The cable accepts termination with screw terminals, solder lugs, banana plugs or bare wire connections depending on amplifier and speaker binding post types.\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\u003eSheath\u003c\/td\u003e\n\u003ctd\u003eClear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePolarity\u003c\/td\u003e\n\u003ctd\u003eRed\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\u003e1.5mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrands\u003c\/td\u003e\n\u003ctd\u003e2 x (45 x 0.2mmØ)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e3.8 x 7.6mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacked quantity\u003c\/td\u003e\n\u003ctd\u003e4 reels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent\u003c\/td\u003e\n\u003ctd\u003e15A 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's the difference between copper clad aluminium and pure copper speaker cable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCopper clad aluminium (CCA) uses an aluminium core with a thin copper coating, offering lighter weight and lower cost than pure copper. Pure copper has better conductivity and is preferred for longer runs or higher-power applications, but CCA performs adequately for medium-power distributed audio where budget is a constraint.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat speaker impedance and run length does this cable suit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 1.5mm² CSA suits 8-ohm speakers on runs up to 15-20m from the amplifier without significant voltage drop affecting performance. For 4-ohm speakers or runs exceeding 20m, consider stepping up to a larger CSA cable to maintain efficiency.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the polarity marking used during installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe red stripe runs along one conductor to mark positive polarity. Connect the red-marked conductor to the positive terminal on both the amplifier and speaker ends of each run, ensuring all speakers are wired in phase across the system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this cable be used outdoors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The clear PVC sheath is not UV-stabilised or rated for outdoor exposure. For outdoor speaker runs, use cable specifically rated for external installation with weatherproof jacket construction.\u003c\/p\u003e","brand":"AVSL","offers":[{"title":"Default Title","offer_id":45313506541835,"sku":"807.049UK","price":30.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/807049UK_LD1_076ea212-14ee-444d-b573-ab37f95ac527.jpg?v=1715194762","url":"https:\/\/niori.co.uk\/products\/mercury-economy-transparent-speaker-cable-2-x-45-strand-100m-reel","provider":"Niori","version":"1.0","type":"link"}
