AudioQuest Black Lab RCA Subwoofer Interconnect Cable

Premium subwoofer interconnect cable engineered for clean, low-noise signal transmission and deep bass performance in home theater systems.

The AudioQuest Black Lab subwoofer interconnect is designed for connecting your subwoofer to receivers or amplifiers with superior signal clarity and minimal distortion. Featuring **solid Long-Grain Copper (LGC) conductors** and **asymmetrical double-balanced geometry**, Black Lab helps preserve dynamic contrast and low-frequency detail for powerful, accurate bass. Its robust design and **high-density shielding** reduce RF/EMI interference, resulting in a cleaner signal path and improved low-end extension compared to generic interconnects.

The cable’s **cold-welded, gold-plated RCA connectors** ensure long-term reliability and excellent contact with your audio components, while the flexible jacket makes routing simple in complex home theater installations. Available in multiple lengths, Black Lab is a versatile choice for systems requiring high-performance subwoofer cabling. 

Key Features

• Solid Long-Grain Copper (LGC) conductors: Reduces distortion caused by grain boundaries to deliver cleaner, more musical bass. 
• Asymmetrical double-balanced geometry: Optimizes signal and ground separation for improved dynamics and clarity.
• High-density shielding: Helps block RF/EMI interference that can muddy low-frequency signals. 
• Gold-plated, cold-welded RCA connectors: Provide corrosion-resistant contact and low-distortion connection without solder. 
• Flexible yet durable jacket: Makes installation and cable routing easier in tight spaces. 
• Multiple length options: Choose from various lengths to match your home theater layout.
