Monoprice 111937 16AWG Flat Pure Copper Speaker Wire 250ft

The Monoprice 111937 Planate Series speaker wire delivers 250 feet of 16AWG pure bare copper in a flat, PVC-jacketed design built for discreet installation. Unlike copper-clad aluminum wire commonly found at similar price points, this cable uses solid copper conductors throughout, providing lower resistance per foot and more consistent signal delivery—particularly important on longer runs in home theater or distributed audio setups.

Its flat construction is the standout practical feature. Where standard round cable creates visible bumps under carpet or requires larger channels in wall cavities, this wire lies flat and nearly disappears into its surroundings. The CL2 in-wall rating means you can run it through walls permanently and meet building code requirements without additional conduit. Polarity identification is handled by printed markings on one conductor, making it simple to keep positive and negative consistent across multiple speaker connections. At 250 feet, the spool is sized for whole-home installations or multiple room runs from a single purchase.
