Monoprice 75ft Coaxial Audio/Video RCA CL2 Rated Cable - Reliable

In this review the Monoprice 75ft Coaxial Audio/Video RCA CL2 Rated Cable is evaluated for use with digital coax S/PDIF, subwoofers and composite video. The bottom line: it is a straightforward, well-built RG6/U cable that delivers clean, interference-free audio and video over long runs, making it a strong choice for installers and home theater owners who need a CL2-rated in-wall option. The review focuses on construction, signal quality, and practical use cases based on the cable's design and reported user experience.

Key Features

• RG6/U construction: The thick RG6/U core provides the impedance and physical heft needed for long runs without noticeable signal loss for S/PDIF and composite video.
• Double copper braid shielding: Dual shielding reduces EMI and RFI interference so digital audio and video remain clear even near other electronics.
• Gold plated RCA connectors: Gold plating on the male RCA plugs helps maintain a reliable, corrosion-resistant connection over time.
• 97 percent oxygen-free copper conductor: The high-purity conductor supports consistent signal transfer and helps retain audio fidelity across 75 ft runs.
• CL2 rated jacket: The jacket is treated for fire safety, making the cable suitable for in-wall routing in residential installations.
• Low capacitance: At 22 pF per foot, the cable minimizes high-frequency loss, preserving digital clocking and video detail.

Who It's For

The cable is aimed at home theater enthusiasts, AV installers, and anyone needing a long-run digital coax or composite video connection. It is particularly useful for connecting S/PDIF sources to receivers or for run-to-subwoofer setups where a 75 ohm cable and solid shielding are important.

Those who need extreme flexibility for tight bends or a micro-sized RCA run might prefer a thinner, more pliable interconnect; likewise, if a balanced XLR or Toslink optical connection is required for specific equipment, this coaxial RCA cable is not the correct interface.

Pros & Cons

Pros

• Well-built with solid, gold plated connectors that resist corrosion and maintain contact quality.
• Double copper braid shielding keeps noise and interference out of the signal path for clean audio and video.
• CL2 rated jacket and robust conductor make it suitable for in-wall installations and long runs up to 75 ft.
• Low capacitance and 75 ohm impedance support reliable S/PDIF digital transmission and composite video.

Cons

• Relatively stiff and thick construction can make tight bends or concealed routing more challenging for some installations.

Frequently Asked Questions

Can this cable be run inside walls?
Yes, the CL2 rating means the jacket meets residential fire safety standards for in-wall routing.

Is this suitable for subwoofer connections?
Yes, the 75 ohm impedance and oxygen-free copper conductor provide a clean, low-noise connection suitable for subwoofers like the SVS SB2000.

Will it carry a digital S/PDIF signal reliably?
Yes, the RG6/U construction and double braid shielding are appropriate for S/PDIF digital coax transmission over the 75 ft length.
