20 ft Black LC-2 Subwoofer Cable - Low Capacitance, Double Shielded

In this review of the 20 ft Black LC-2 subwoofer cable the bottom line is simple: buyers who need a reliable RCA connection for a powered subwoofer will appreciate its low capacitance and heavy shielding. The reviewer found it especially useful in setups where hum, RF noise, or muddy low-frequency response had been a problem. Built with a coaxial but low-capacitance geometry and two braid shields, this cable is aimed at people who want cleaner bass transfer and fewer grounding headaches without changing electronics or adding noise filters.

Key Features

• Purpose-built design: The LC-2 is engineered specifically for unbalanced RCA audio to improve subwoofer signal integrity compared with ordinary coax.
• Double shielding: Two high-coverage bare copper braids laid one over the other provide strong protection against induced noise at audio frequencies.
• Hum prevention: Low shield resistance and heavy coverage reduce ground potential differences and help prevent ground-loop hum in mixed-equipment systems.
• Low capacitance: A foamed dielectric and generous spacing keep capacitance near 12 pF/ft, preserving bass transients and clarity over the 20 ft run.
• Flexible construction: Despite its thick cross-section the soft PVC jacket and foam core make the cable easy to route behind furniture or along baseboards.
• Quality connectors: Gold-plated Taversoe RCA plugs with a circular leaf spring deliver firm contact without excess tightness that can stress jacks.

Who It's For

This cable is for home theater and music enthusiasts who use a powered subwoofer connected by RCA leads and want to reduce hum, RF intrusion, and tonal smearing in the bass. Installers who need a 20 ft run will value the low capacitance that helps retain tight, defined low frequencies across the distance.

It is less suited to those who require balanced XLR connections, digital subwoofer links, or runs far longer than 20 ft where different cable types or line-level converters would be more appropriate.

Pros & Cons

Pros

• Excellent shielding and low shield resistance noticeably cut induced noise and reduce hum risk.
• Low capacitance construction helps maintain bass definition over the 20 ft length.
• Solid build and flexible jacket make routing and long-term use straightforward.
• Gold-plated RCA plugs provide reliable, low-resistance contact without excessive tightness.

Cons

• Being a purpose-built unbalanced RCA cable, it does not replace balanced cable needs; those requiring XLR should look elsewhere.
• The thicker construction is more robust but can be slightly more conspicuous when run in visible areas.

Our Verdict

The 20 ft Black LC-2 is a practical, well-made RCA subwoofer cable for anyone battling hum or loss of bass clarity over typical home runs. Its combination of low capacitance, heavy shielding, and reliable connectors delivers measurable benefits in real-world setups, making it good value for those focused on clean low-frequency performance.

Frequently Asked Questions

Will this cable reduce subwoofer hum?
Yes; the heavy double braid shielding and low shield resistance are designed to cut induced noise and reduce ground potential differences, which often reduces hum.

Is this suitable for long runs in a home theater?
For typical home runs up to 20 ft this cable preserves bass detail thanks to low capacitance; runs much longer than 20 ft may benefit from alternative solutions.

Are the connectors safe for delicate receiver jacks?
The gold-plated Taversoe RCA plugs use a circular leaf spring for firm contact without the excessive tightness that can damage jacks.
