Enhance your home audio experience with Monoprice™ Speaker Wire, CL2 Rated. Crafted with high‑quality pure bare copper, this speaker wire enables you to unlock the full potential of your audio system.Unlike inexpensive speaker wires that utilize copper clad aluminum (CCA) conductors, our Pure Bare Copper wire boasts superior conductivity. CCA conductors are only about 68% as conductive as pure bare copper, meaning they introduce additional resistance to the impedance of your speakers, ultimately impacting the sound quality.To ensure minimal audible effects, it is crucial for the total wire resistance to be less than 5% of the lowest impedance of your speakers. Even speakers with an 8‑ohm nominal rating can dip to as low as 4‑ohms at certain frequencies, further limiting the allowable cable resistance. By utilizing Pure Bare Copper speaker wire, you can maintain a load on the amplifier that closely aligns with the impedance curve of your speakers.For easy polarity identification, each conductor of the wire is jacketed with color‑coded PVC. The entire cable assembly is encased in a black, CL2‑rated PVC material. The CL2 rating signifies compliance with fire safety and insurance requirements, ensuring that this wire is safe for installation within the walls of residential class buildings.With Monoprice™ Speaker Wire, CL2 Rated, you can optimize your audio system's performance, minimize impedance issues, and enjoy exceptional sound quality.
