40 ft Subwoofer RCA Cable LC-2 (Black) - Double Shielded Low

In this review the focus is on whether the LC-2 40 ft subwoofer cable is the practical choice for anyone battling hum, interference, or muddy low-end from long unbalanced runs. The bottom line: the cable is aimed at homeowners and installers who need a long RCA lead that keeps noise out while preserving bass detail. Its combination of double bare-copper braids and a foamed dielectric produces low capacitance and low shield resistance, which directly addresses common subwoofer issues without forcing a move to balanced wiring.

Key Features

• Custom coaxial geometry: Designed specifically for unbalanced RCA audio so it lowers capacitance compared with ordinary coax, preserving signal clarity over long runs.
• Double bare-copper braids: Two high-coverage braids laid over each other provide heavy shielding that reduces induced noise at audio frequencies.
• Hum prevention: Low shield resistance and excellent coverage work together to reduce ground potential differences and the likelihood of ground loop hum.
• Low capacitance: A foamed dielectric and large spacing keep capacitance around 12 pF/ft, which helps maintain transient detail and bass definition.
• High flexibility: Despite its thickness, a soft PVC jacket and foam dielectric make the cable easy to route around furniture and through racks.
• Quality connectors: Gold-plated Taversoe RCA plugs with a circular leaf spring provide secure contact without damaging jacks.

Who It's For

The LC-2 40 ft is best for home theater owners, AV installers, and audiophiles who must run long unbalanced RCA cables to a powered subwoofer and want reliable hum rejection and low signal loss. It suits situations where balanced lines are not available or practical and the priority is cleaner bass and lower noise on long runs.

Those who already use balanced XLR or dedicated low-noise subwoofer outputs may not see as big a benefit from this cable, and compact systems that need under 6 ft of cabling could choose lighter, simpler leads instead.

Pros & Cons

Pros

• Heavy dual-braid shielding effectively blocks RF and induced noise, improving noise floor.
• Low capacitance maintains bass clarity and transient response on long runs.
• Flexible construction and gold-plated Taversoe RCA plugs make installation simple and reliable.
• Made in Seattle, Washington, with attention to build quality and connectors.

Cons

• Thicker construction is less discreet in tight cable management situations compared with slim patch cords.
• Only designed for unbalanced RCA use, so systems needing balanced connections will require different cabling.

Frequently Asked Questions

Will this cable eliminate subwoofer hum?
The cable reduces common causes of hum by excluding induced noise and lowering shield resistance, which often noticeably reduces ground loop hum, though complete elimination depends on the system grounding.

Is it flexible enough to route behind furniture?
Yes, the LC-2 uses a soft PVC jacket and a foamed dielectric that make it more flexible than typical thick coax cables, easing routing in tight spaces.

Is this suitable for balanced connections?
No, this cable is optimized for unbalanced RCA analog audio; balanced XLR lines require different cabling.
