The Supra Classic 4.0 Blue Speaker Cable 6m w/ QED Metal Airloc is ideal for wiring up hi-fi and home cinema setups. The Supra Classic is a tried and tested performance speaker cable that has been the staple of Supra Cables success almost since they were started in 1976. The Classic 4.0 features large tin-plated OFC conductors making it best suited with large performance-demanding loudspeakers. The anti-corrosive qualities of plating in tin further enhance audio reproduction by reducing the skin-effect which often blights cheaper cables. The cable comes fitted with QED Plastic Airloc banana plugs ensuring optimal signal integrity. Please Note: This cable comes pre-built images are for reference only.
