Speaker Wire - CL3 in-Wall Rated, 2-Conductor, Color Coded, 12AWG, 250 Feet, White

Pure Bare Copper: Pure Bare Copper is a more effective conductor than the copper clad aluminum (CCA) conductors found in many other low-cost speaker wires. CCA is only about 68% as conductive as pure bare copper; its extra resistance increases speaker impedance, adversely impacting sound quality. CL3 In-Wall Rated: The CL3 rating signifies the cable's adherence to fire safety and insurance standards. It is approved for installation within the walls of residential buildings. A CL3 rating can handle a surge of up to 300 watts, which is twice the capacity of a CL2 rating (150 watts). Features a superior conductor in comparison to Copper Clad Aluminum (CCA). Color-coded PVC jacket enables simple polarity identification. The spool contains 250 continuous feet of speaker wire
