AudioQuest Black Lab Subwoofer Cable
Best subwoofer cable for audiophiles seeking cleaner, more precise bass performance.
This AudioQuest Black Lab subwoofer cable, measuring 8 meters, is an open-box A-grade item. It features solid Long-Grain Copper conductors, which offer a smoother and clearer sound compared to standard OFHC copper by minimizing oxides, impurities, and grain boundaries. The cable utilizes air-filled Foamed-Polyethylene Insulation, a low-loss dielectric that absorbs minimal energy and has a benign distortion profile, reducing the "out-of-focus" effect. Additionally, its Noise-Dissipation System effectively prevents RFI from reaching the equipment's ground plane, ensuring a cleaner audio signal.

Know before you buy
Long-Grain Copper contains fewer oxides and impurities than standard copper. This design helps minimize signal distortion, resulting in a cleaner, more focused sound for your subwoofer.
This system prevents radio-frequency interference (RFI) from entering your equipment's ground plane. By blocking this external noise, the cable ensures your subwoofer receives a purer signal, which is essential for tight, accurate bass.
The cable uses air-filled Foamed-Polyethylene insulation, which is a low-loss dielectric material. This design minimizes energy absorption, allowing the signal to remain stable and clear even over an 8-meter run.
The AudioQuest Black Lab uses standard RCA connectors. It is compatible with the vast majority of home theater subwoofers and receivers that feature a dedicated subwoofer output.
An A-grade open-box item is essentially in like-new condition. It has been inspected to ensure it functions perfectly and meets all performance standards, offering you a high-quality cable at a better value.
