White LC-2 Subwoofer Cable 40 ft - Double-Shielded Low Capacitance

In this review of the White LC-2 40 ft subwoofer cable, the bottom line is simple: this cable is for people who want a clean, low-noise analog connection between an amp and a powered subwoofer without fuss. The reviewer found the cable's biggest advantage to be its combination of heavy shielding and unusually low capacitance, which together reduce hum and preserve bass clarity over long runs. For anyone battling ground-loop hiss or RF interference in a home theater or studio, this cable consistently improves signal cleanliness.

Key Features

• Double shielding: Two high-coverage bare copper braids laid over one another reject induced noise and protect the audio band.
• Low capacitance: About 12 pF/ft thanks to a foamed dielectric and large spacing, which helps preserve low-frequency detail over long runs.
• Hum prevention: Low shield resistance and robust shielding reduce ground potential differences and the likelihood of ground-loop hum.
• Flexible construction: A soft PVC jacket and foam dielectric keep the thick cable surprisingly flexible for routing under furniture or behind racks.
• Quality connectors: Gold-plated Taversoe RCA plugs with a circular leaf spring give secure contact without over-tightening jack sockets.
• Handbuilt in Seattle: Assemblies are built by American workers, which contributes to consistent build quality.

Who It's For

The White LC-2 40 ft is aimed at home theater owners, audiophile hobbyists, and small studio operators who use unbalanced RCA connections for a subwoofer and need a long run that resists hum and RF contamination. It is particularly useful where ground loops or nearby electrical cabling create audible noise.

This cable is less relevant for people who rely exclusively on balanced XLR or speaker-level connections, or those who need a very thin, minimalist patch cable for short runs under 3 ft. Also, if you need a completely rigid breakaway cable for fixed installation, a thicker but less flexible alternative might be preferred.

Pros & Cons

Pros

• Excellent shielding performance that reduces induced noise and RF intrusion.
• Low capacitance that helps maintain bass definition and timing over long runs.
• Solid build and flexible jacket make routing easier without feeling fragile.
• Gold-plated RCA plugs provide reliable contact and longevity.

Cons

• Thicker cable profile can be more visible and slightly less tidy for some installations.
• Specifically optimized for unbalanced RCA; those using balanced connections should choose a different cable type.

Specifications

Our Verdict

The White LC-2 40 ft is a practical upgrade for anyone needing a long unbalanced subwoofer run with minimal hum and preserved bass clarity. Its combination of heavy shielding, low capacitance, and sturdy connectors makes it good value for installations where noise rejection matters more than an ultra-slim profile.

Frequently Asked Questions

Will this cable reduce subwoofer hum?
Yes. The double shielding and low shield resistance address induced noise and ground potential differences, which commonly cause hum.

Is this suitable for long runs?
Yes. Low capacitance at about 12 pF/ft helps maintain signal integrity over the 40 ft length.

Are the connectors durable?
The gold-plated Taversoe RCA plugs have a circular leaf spring for firm engagement and are built for repeated use.
