Monoprice 103844 250ft 12AWG CL2 Rated 2-Conductor Loud Speaker Cable (for in-Wall Installation) & 102684 50-Feet RG6 RCA CL2 Rated Digital Coaxial Audio Cable Black

Monoprice 103844 250ft 12AWG CL2 Rated 2-Conductor Loud Speaker Cable (for in-Wall Installation)
Get the most out of your home audio system with high quality, oxygen-free, pure bare copper speaker wire from monoprice!
this speaker wire features two conductors made of high purity (greater than 99.95% pure), oxygen-free bare copper. 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.
for example, a 16AWG 2-conductor pure bare copper speaker wire has a total resistance of 0.803 ohms per 100 feet (both directions must be considered). by comparison, a 16AWG 2-conductor CCA speaker wire has a total resistance of 1.181 ohms per 100 feet. Assuming 4 ohms is the lowest impedance of your speakers, a speaker wire run can be no more 0.2-Ohms total. 20 feet of 16AWG pure bare copper would be 0.1606 ohms, well under the 0.2-Ohm limit. On the other hand, 20 feet of 16AWG CCA would be 0.2362 ohms, well over the 0.2-Ohm limit.
each conductor is jacketed with color-coded PVC for easy polarity identification. The entire cable assembly is jacketed in a white, 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.

Monoprice 102684 50-Feet RG6 RCA CL2 Rated Digital Coaxial Audio Cable Black
This Digital Coax Cable is made from premium quality RG-6/U with double copper braid shielding to prevent signal degradation caused by EMI and RFI interference. This cable is ideal for conducting S/PD if digital audio signals and other high-bandwidth content but it can also be used for composite video and other line level RCA signals. The CL2 rating on this cable indicates that the jacket has been treated so that it complies with fire safety regulations making it safe for use through or within the walls of residential class buildings. Features: . gold plated RCA male connectors. Rubber-covered molded connector housings. 97% pure oxygen-free copper conductor. Double shielded with copper braiding. 22 PF per foot capacitance. 75 Ohm impedance
