Monoprice Speaker Wire CL2 Rated 16AWG 100ft - In-Wall Ready

Our review of the Monoprice Speaker Wire CL2 Rated 16AWG 100ft finds it to be a straightforward, dependable choice for homeowners and hobbyists who need in-wall safe wiring for audio systems. The single biggest reason to buy is the combination of high-purity, oxygen-free copper conductors and a CL2-rated outer jacket, which together deliver reliable signal transfer and meet common residential fire-safety requirements for concealed runs. This cable is best when you want neat, color-coded polarity identification and enough length on a spool to reach typical room-to-room speaker placements.

Key Features

• Oxygen-free copper: The conductors are made from greater than 99.95% pure copper to reduce resistance and preserve signal clarity for speakers.
• CL2-rated outer jacket: The white PVC jacket is CL2 rated so the cable is suitable for in-wall use in residential class buildings and complies with common safety requirements.
• Two-conductor design: The 2-conductor construction provides a simple, standard hookup for most home and surround sound speaker installs.
• Color-coded conductors: Each conductor has an individual color-coded jacket inside the outer jacket to make polarity identification and termination easier and faster.
• 100 ft spool: The full 100 continuous ft on a spool gives plenty of length for multiple speaker runs without splicing.

Who It's For

This cable is aimed at homeowners, DIY installers, and installers of modest home theater or multiroom audio systems who need an in-wall rated speaker cable that balances cost and performance. It is particularly useful for running front, rear, or surround speakers where a clean, concealed installation is preferred.

Customers who require specialty high-power, ultra-long-distance commercial runs, or exotic audiophile cable constructions looking for visual or bundle shielding beyond standard PVC jackets should look elsewhere. For typical residential speaker wiring, however, this cable covers the common requirements without unnecessary complexity.

Pros & Cons

Pros

• Good conductor quality from oxygen-free, high-purity copper that supports clean signal transmission.
• CL2-rated white outer jacket allows safe in-wall installation meeting residential requirements.
• Color-coded inner jackets make polarity identification and hooking up speakers quick and error-free.
• 100 ft spool provides ample length for most room-to-room speaker layouts and simple projects.

Cons

• PVC jacket and standard 16AWG size are fine for most rooms but may not satisfy specialty high-end shielding or very long-run needs.
