QED Performance Y-SW Adapter


The Performance Subwoofer Y adapter is designed for use with active subwoofers that require both left and right channels to be connected for best performance. It can also be used wherever a signal needs to be split between two pieces of equipment such as when bi-amping. Includes Oxygen Free Copper conductors and dual magnetic shielding for enhanced signal integrity to ensure that you get the best from your subwoofer.

  • 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 electrostatic shielding for enhanced signal integrity. 

  • 24k gold plated RCA connectors. Gold is used because it will not tarnish thus providing a long lasting low contact resistance connection

  • Precision engineered plug with Integrated grip
