The SUPRA story
Prior to 1976 loudspeaker cables had no identity. They were simply cables. 2 x 0.5 sqmm was the most usual size, while for high specifications the only alternative was 2 x 0.75 sqmm.
And then SUPRA changed all that!
It began when we introduced SUPRA 2.5 and shook up the entire market with the new concept of quality specific cables. All this happened in Sweden 1976. Since then the whole world has followed after us. But then the adjustable spanner, the propeller, the safety pin and Dynamite have also come from Sweden, so perhaps it is not so surprising.
Since SUPRA 2.5 was introduced, other original ideas have come from SUPRA. The nylon screen, the Swift connector, the stretch-proof multicore cable and the Ply conductor concept, and the Assurance of Cable Directionality are all examples of our forward thinking technology.
