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, for connecting passive speakers to amplifiers and sound systems.\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\u003eWith the usual criterion of keeping the cable resistance below 5 % of the speaker impedance, with an 8 ohm speaker \u003cstrong\u003eit is best not to exceed about 19 metres per speaker\u003c\/strong\u003e with this cross-section in CCA; with a 4 ohm one, about 10 metres.
