AudioQuest Sub-3 Subwoofer Cable

The Dielectric-Bias System (DBS) creates a constant electrostatic field that polarizes the cable's insulation. This minimizes time-smear and signal distortion, resulting in cleaner, more defined bass performance.

The triple-balanced geometry uses separate conductors for the positive and negative signals, while the shield is used only for grounding. This configuration effectively isolates the signal path from interference, which is critical for the low-frequency signals handled by subwoofers.

Yes, this cable features an integrated ground wire with spade lugs. It is designed to help eliminate ground loop hum, which can sometimes occur in complex home theater systems where multiple components are connected.

A 7/10 rating indicates the cable is fully functional but shows minor cosmetic wear, specifically on the connectors and the DBS pack housing. The cable sleeve itself remains in excellent condition, so the performance is unaffected.

Yes, this cable uses standard RCA male-to-RCA male connectors, making it compatible with the vast majority of powered subwoofers and AV receivers on the market.
