Each core comprises 16 strands of 0.2mm diameter wire, giving a combined cross-sectional area of 0.5mm² per conductor. The cable is rated for a maximum current of 2.5A and suits low-power distributed audio installations where copper cost is a limiting factor.\u003c\/p\u003e\n\u003cp\u003eDesigned for budget background music systems, small retail installations and multi-room audio where cable runs exceed 50m and pure copper cost becomes prohibitive, the copper-clad aluminium construction reduces material cost whilst maintaining acceptable conductivity for 8-16 ohm passive speaker loads at moderate power levels. The figure-8 profile (2.2 x 4.4mm) allows the two cores to be separated cleanly at termination points without needing to strip outer sheathing, speeding installation in ceiling voids and under flooring.\u003c\/p\u003e\n\u003cp\u003eThe red and black colour-coding on the outer sheath helps maintain correct polarity across multi-zone installations. Copper-clad aluminium has higher resistance than pure copper, so this cable is not recommended for critical listening applications, subwoofer runs, or high-current amplifier outputs above 50W per channel. For domestic hi-fi or professional sound reinforcement, use pure copper cable instead. The 100m reel suits installers working on commercial projects where multiple rooms or zones need wiring from a single supply point.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\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\u003eRed\/Black\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\u003e0.5mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrands\u003c\/td\u003e\n\u003ctd\u003e2 x (16 x 0.2mmØ)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e2.2 x 4.4mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacked quantity\u003c\/td\u003e\n\u003ctd\u003e10 reels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent\u003c\/td\u003e\n\u003ctd\u003e2.5A max.\u003c\/td\u003e\n\u003c\/tr\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 has a thin copper coating over an aluminium core, which reduces material cost but increases electrical resistance compared to pure copper.
