The Black Lab Rca subwoofer cable is engineered to elevate low frequency performance by delivering clean powerful bass with exceptional detail for home theater and music systems. Solid long grain copper conductors reduce distortion for smoother more accurate signal transfer while foamed polyethylene insulation preserves delicate dynamics by minimizing energy loss. A metal layer noise dissipation system shields against interference for a quieter background. Cold welded gold plated plugs ensure a secure long lasting connection and symmetrical coaxial geometry keeps signal paths balanced so your subwoofer sounds tight deep and controlled.
