QED Performance Subwoofer


The mutli-award winning Performance category, renowned for extraordinary performance at exceptional value presents Performance Subwoofer. This cable features dual electro-static shielding for enhanced signal integrity and quasi-balanced twisted pair geometry to provide a pure, noise free experience.  QED is so proud of this product that we offer a lifetime guarantee.


  • 99.999% Oxygen Free Copper Conductors. Oxygen free conductors will stand the test of time to provide you with the QED experience for life.

  • Quasi-Balanced twisted pair geometry. Brings superior noise immunity to unbalanced audio connections by using a twisted pair for the signal and return paths thus introducing a level of common mode noise rejection not present in conventional cables.

  • Dual electro-static shielding for enhanced signal integrity. Protects delicate signals against interference from external high voltages over long cable runs. The shield should ideally be connected at the source end, hence the directionality arrows printed on the cable jacket.
  • 24k gold plated RCA connectors. 24k gold plated RCA connectors firm and low resistance connection. Gold is used because it will not tarnish thus providing a long lasting low contact resistance connection
  • Precision engineered plug with integrated grip
  • QED lifetime guarantee
