Monoprice 16AWG Flat Pure Copper Speaker Wire 100ft

Monoprice 16AWG Pure Copper Flat Speaker Wire is a 100-foot, CL2 in-wall rated, flat jacketed cable made from pure bare copper for reliable home audio connections.

This Monoprice flat speaker wire is designed for clean runs behind baseboards, under carpets, or through walls where a low-profile, discrete cable is preferred. The Planate Series 16 AWG conductor uses pure bare copper — not copper-clad aluminum — to provide consistent conductivity for passive speakers and common home audio setups. The PVC flat jacket keeps the wire slim and easy to route while the CL2 rating permits safe in-wall installation according to common residential standards.

What makes this speaker wire different from standard round wire?

The flat profile reduces bulk and simplifies routing in tight spaces where round cables bunch or show under trim. Because one conductor is marked, identifying polarity during installation is faster and less error-prone. The pure bare copper conductors give better conductivity than copper-clad aluminum alternatives at the same gauge.

• Flat PVC jacket lies flat under carpets and along baseboards for discreet runs.
• One conductor is marked for easy polarity identification and consistent speaker phase.
• Pure copper conductors reduce resistance compared to CCA at 16 AWG size.
• CL2 in-wall rating allows installation through interior walls where permitted.

How will 16 AWG performance affect my speakers?

16 AWG is commonly used for bookshelf and satellite speakers or longer runs to small-to-medium drivers. It balances flexibility and current-carrying ability while remaining easy to conceal. For very long runs or high-power amplifiers, a thicker gauge might be preferable, but for most home theater and stereo layouts 16 AWG meets typical needs.

• Suitable for short-to-moderate runs to bookshelf and surround speakers.
• Maintains low-loss transmission for most consumer amplifiers at typical distances.
• Flexible enough to route around corners and through tight channels.

Is this safe to use inside walls and what does CL2 mean?

The CL2 classification is a common U.S. in-wall rating indicating the cable meets flame-resistance and insulation standards for residential vertical applications. That rating simplifies meeting local building-code expectations for speaker wiring inside walls, closets, and similar interior spaces when installed properly. Always follow local building codes and, when in doubt, consult a licensed electrician or contractor.

• CL2 rating indicates compliance with residential in-wall flame-resistance standards.
• PVC jacket provides insulation and a slim profile for concealment.
• Proper installation practices and local code compliance are essential.

How easy is this cable to install and connect to equipment?

The flat design and marked conductor speed up routing and polarity identification during setup. The PVC jacket can be stripped with common wire strippers to reveal the two pure copper conductors for bare-wire or connector terminations. Its flexibility allows neat runs along trim, behind entertainment centers, or under carpeting with minimal visibility.

• Strip the PVC with standard wire strippers to expose copper conductors.
• Marked conductor reduces polarity errors during speaker hookup.
• Flat profile simplifies concealment and keeps runs tidy and low-profile.

Who is this for? Installers, DIY home theater builders, and anyone who needs a low-visibility, in-wall-capable speaker cable will appreciate the Monoprice 16AWG pure copper flat wire. It fits applications where a discreet run matters — behind wall trim, under rugs, or through wall cavities — while offering the conductivity of bare copper and an in-wall CL2 jacket. Choose this cable when you want a balance of appearance, ease of routing, and reliable electrical performance for most home audio setups.
