About the Big 4

The Straightwire Big-4 speaker cable is a reference-level product from Straight Wire, engineered for those who demand the highest performance from their audio components. It features seven equal diameter TPR hollow tubes in the inner core for enhanced flexibility and reduced mechanical resonance, contrasting with traditional single large PE tubes. The cable uses Oxygen Free High Conductivity (OFHC) copper conductors and polypropylene insulation arranged in a quad twist to ensure accurate midrange and vocal reproduction, controlled bass, and a detailed, lifelike presentation. The design supports internally bi-wireable (IBW) configurations and comes with a matte putty color jacket. This cable is part of Straight Wire's Level 4 series, which is positioned as a top-tier offering for audiophiles seeking unsurpassed musical satisfaction.
