This cable is used to make the electrical connection between loudspeakers and audio amplifiers, and also used for the internal wiring of the speakers themselves.


High Conductivity Copper

All Coboc speaker cables utilize high-conductivity 99.95% pure, oxygen-free copper.

Marked Polarity

One side of the wire insulation is marked with a blue stripe, making it quick and easy to identify the correct audio signal polarity.

Easy and Convenient Installation

Coboc 18-gauge speaker wire comes wrapped around a hard spool that makes installation easy and convenient.

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 (4Ω, 8Ω 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 4Ω Speaker 8Ω 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


Attenuation = -10lg (Pout/Pin)

Attenuation 3dB is commensurate with a 50% power loss.


The maximum distance for 12 AWG in a 4 Ohm speaker system with 11% or 0.5dB loss is 140ft.


Coboc 1-Year Limited Warranty.
