The Mogami W2921 professional speaker cables are originally designed to deliver maximum performance from state-of-the-art Tri-Amp Systems. They offer true audiophile performance for accurate sound transmission with clear transparent response, yet possess a rugged superflexibility for the most demanding professional applications. Each conductor features many strands in rope-lay of famous MOGAMI 'NEGLEX' Oxygen-Free-Copper within color-coded PVC insulation. A tough, low profile matte black superflexible PVC jacket protects the cables.
