Monoprice 104043 100 ft 18AWG CL2 Rated 4 Conductor Oxygen Free Pure Bare Copper Speaker Wire Cable

Pure Bare Copper is a superior conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire This additional resistance is added to the impedance of your speakers and can negatively effect the sound. Even speakers rated for a nominal 8-ohms, may dip to as low as 4-ohms at some frequencies, which further reduces the total cable resistance allowed in the wire For the wire to have no audible effect, the total wire resistance should be no more than 5% of the lowest impedance of your speakers
