Description:
This is the right cable to install audio throughout your house. this speaker wire is very flexible and less likely to kink during installation. CL2-rated for use inside walls, this wire features a flame-retardant white PVC jacket that helps to diminish the potential of fire spreading between floors.
The wire's design features conductors twisted upon each other that makes the cable round and much easier to pull throughout the house than the flat or zip-cord style. Inner conductors are color-coded for easy identification.
Application:
This speaker cable is used to make the electrical connection between loudspeakers and audio amplifiers, and also used for the internal wiring of the speakers themselves.

Keep Your Home and Family Safe with In-Wall-Rated Speaker Wire
When you're running wire inside your walls, it's important that you use speaker cable that's approved for in-wall runs. This cable's CL2 certification means it passed safety tests administered by the Underwriters Laboratory (UL). The UL looks at heat generated from current flowing through wire, how quickly the cable will catch and spread fire when exposed to flame, and the wire's susceptibility to damage from external stresses. Also, be sure to check your local building and fire codes, and buy wire accordingly.
Gauge Selection:
Different people will have their own opinions about what gauge is proper for what length. The quality of the equipment can also play a factor. The following is a general guide for picking gauges for certain lengths.
0 - 25ft - 18AWG
25 - 50ft - 16AWG
50 - 75ft - 14AWG
75 & up - 12AWG
Selecting the Correct Speaker Wire for the Application
Based on the following questions, use the table as reference to select the proper gauge size
1. What is your speaker type (4, 8 or 70-Volt)?
2. What is the acceptable power loss (11%, 21%, 37% or 50%)?
Move down the column to select the wire AWG size that meets your distance requirement in feet.
Wire AWG Size | 4 Speaker | 8 Speaker | 70-Volt Speaker | ||||||
Power Loss (%) / Attenuation (dB) | |||||||||
11% | 21% | 50% | 11% | 21% | 50% | 11% | 21% | 50% | |
0.5dB | 1.0dB | 3.0dB | 0.5dB | 1.0dB | 3.0dB | 0.5dB | 1.0dB | 3.0dB | |
12 | 140 | 300 | 1145 | 280 | 605 | 2280 | 6780 | 14590 | 54880 |
14 | 85 | 190 | 735 | 180 | 390 | 1475 | 4395 | 9455 | 33570 |
16 | 60 | 125 | 465 | 110 | 245 | 930 | 2780 | 5975 | 22490 |
18 | 40 | 90 | 340 | 85 | 190 | 680 | 2025 | 4360 | 16385 |
Note:
Attenuation = -10lg (Pout/Pin)
Attenuation 3dB is commensurate with power loss 50%.
