With its four separated wires, where each is made of a perfect mix of Pure Copper Ultra High Drawability (PCUHD), HiFC (High-performance pure copper), and OFC (Oxygen Free Copper), this cable is optimized for either bi-wiring or for combining wire two by two, to double the conductor area. This lowers the impedance of the cable, which responds faster and thereby sounds more clear and neutral in the entire frequency span. All four wires are surrounded by a high-density shield to eliminate environmental noise from other kinds of electrical equipment. 

The SPK Bronze has an astonishingly wide range, clear and neutral sound.
