Monoprice Speaker Wire, CMP Rated, 2-Conductor, 14...
Monoprice Plenum Speaker Wire is designed to meet the most stringent standards of safety for both residential and commercial applications. The fire-retardant cable jacket bears the CMP plenum air space safety rating, making it ideal for use in any situation. Available in a variety of lengths and gauges, you can choose two-conductor versions, for connecting a single speaker, or four-conductor versions for connecting speaker pairs. The pure bare copper conductors are sheathed in color-coded jackets contained with the main CMP-rated jacket. Backed up by Monoprice's Lifetime Warranty, Monoprice Plenum Speaker Wire series is the ultimate speaker wire for commercial and residential installations.
Plenum Rated: Monoprice Plenum Speaker Wire uses an external cable jacket, which has been specially treated to resist the spread of fire. It has been CMP rated as safe for use in the plenum ducts and airspaces of commercial class buildings, making it the ideal speaker wire choice for any situation.
100% Pure Bare Copper: Featuring pure bare copper conductors, these speaker wires faithfully and accurately reproduce music with total sonic clarity.
Various Lengths and Gauges: Available in 12, 14, 16, and 18 AWG sizes, and in 50, 100, 250, and 500 foot lengths, Monoprice has the speaker wire that is perfect for your needs.
2 or 4 Color-Coded Conductors: Connect a single speaker using the 2-conductor wire or connect a stereo pair using the 4-conductor variant. Each version has uniquely colored inner jackets so you can easily match polarity at each end.
Soft and Flexible Cable Jacket: While most plenum rated cables are stiff, Monoprice Plenum Speaker Wire uses a specially treated jacket, which keeps it as soft and flexible as ordinary speaker cable.
Monoprice Speaker Wire, CL2 Rated, 4-Conductor, 14...
Get the most out of your home audio system with high quality, pure bare copper speaker wire from Monoprice™!
Pure Bare Copper is a superior conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire. CCA is only about 68% as conductive as pure bare copper. This additional resistance is added to the impedance of your speakers and can negatively effect the sound.
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. 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. Using Pure Bare Copper speaker wire ensures that the total load put on the amplifier remains as close as possible to the impedance curve of your speakers.
Each conductor is jacketed with color-coded PVC for easy polarity identification. The entire cable assembly is jacketed in a black, CL2-rated PVC material. The CL2 rating indicates that the cable complies with fire safety and insurance requirements, making it safe for use inside the walls of residential class buildings.
