BlueRigger 50ft RCA Subwoofer Cable — Dual Shielded

BlueRigger's 50-foot RCA audio subwoofer cable is a dual-shielded, gold-plated connection designed to deliver low-frequency audio from receivers or amplifiers to subwoofers with minimal loss and reliable in-wall installation.

If you need a single long run to link a powered subwoofer or amplifier to a home theater receiver, this BlueRigger cable is built for that job: pure copper-clad center conductor, dual shielding to reduce interference, split-tip gold-plated RCA connectors for secure contact, and CL3 in-wall rating for safe concealed routing. The cable focuses on carrying LFE and low-frequency audio signals cleanly so your bass remains tight and detailed even over long distances.

How does this cable protect bass quality over 50 feet?

The cable uses a 0.64 mm pure copper-clad center conductor and dielectric insulation to reduce signal attenuation on low-frequency channels. Dual shielding (foil plus braid) minimizes hum and radio-frequency interference that can muddy bass. Together these elements keep the low-end response stable across extended runs.

• 0.64 mm copper-clad center for low-loss signal transfer
• Foil and braided shields reduce electromagnetic noise
• Dielectric insulation preserves waveform integrity

Are the connectors reliable for frequent plugging and in-wall use?

BlueRigger fitted each end with split-tip, 24K gold-plated RCA plugs that resist corrosion and maintain a snug fit in RCA jacks. Split center pins increase contact pressure and conductivity, reducing intermittent connections common with cheap cables. Additionally, single RCA runs carry a CL3 rating, making them suitable for concealed in-wall routing when local codes allow.

• 24K gold-plated RCA connectors for corrosion resistance
• Split-tip center pins for improved contact and signal flow
• CL3 in-wall rating for safe concealed installation (single run)

Will this cable reduce hum and interference in multi-device setups?

Yes — the combination of dual shielding and a solid outer PVC jacket helps reduce hum from nearby power cables and components. The braid handles low-frequency noise while the foil layer blocks high-frequency interference, a helpful pairing where A/V equipment racks are crowded. The durable jacket also prevents microphonics and cable deformation that can introduce noise.

• Braid shield tackles low-frequency hum
• Foil shield blocks RF and high-frequency noise
• PVC jacket resists kinking and mechanical noise

What installation scenarios is this cable best suited for?

This 50-foot RCA is ideal when your subwoofer or amplifier sits far from the receiver, such as in basements, large living rooms, or multi-room systems. It's also appropriate for in-wall runs when you need a clean, hidden cable path and comply with CL3 requirements. For short, exposed connections you still get the same shielding benefits and tough exterior.

• Long-distance subwoofer runs up to 50 feet
• Concealed in-wall routing where CL3 single-run is required
• Home theater racks, AV closets, and multi-room audio

Who is this for: Audiophiles, home theater builders, and installers who want a dependable, long-length RCA subwoofer cable that balances low-frequency fidelity with real-world durability. Choose BlueRigger when you need a long run that resists interference, maintains a secure connector fit, and meets in-wall safety standards for tidy, permanent installs.
