The ALS Series cables are parallel designed loudspeaker cables, based on CCA (Copper Clad Aluminium). This is a technology where an outer sleeve of copper is bonded to a solid aluminum core.
The result is a cable with characteristics lying between those of copper cables and bare aluminum cables. It combines the advantages from two sides, such as solderability, lower weight and lower material cost than bare copper with the higher conductivity and higher strength than pure aluminum.
The cable composition is made of 85% aluminum with 15% copper, this is combined with a highly flexible jacket made of PVC
