The Planet Waves Speaker Cable with Compression Spring Plugs, PW-SCS-25 is completely new and innovative. Ordinary plug/jack connections can become unreliable. Planet Waves Custom Series cables with patented compression springs allow the plug to positively lock into the jack, eliminating any annoying static, signal loss, or accidental pull-out. Using the latest in cable manufacturing technology, the Custom Series line features ultra-pure twisted pair, oxygen -free copper conductors with encapsulated soldering points formulated for extremely low capacitance. Additionally, two layers of impenetrable noise-rejecting shielding, coupled with unmatched moulded strain relief, deliver the ultimate high-performance cable.
