The QED Performance Speaker Cable is well suited to stereo and home cinema systems requiring a reliable connection between an integrated amplifier or power amplifier and loudspeakers. Its 2.5 mm² conductor cross-section makes it suitable for a wide variety of hi-fi systems, while X-Tube Plus™ technology is designed to maintain more consistent current distribution across the frequency range. Choose a length that allows the cable to be installed without tension or sharp bends and, where practical, use similar cable lengths for the left and right channels.
