Amazon Basics Speaker Wire - 14-Gauge, 99.9% Oxygen-Free Copper, 30,5 m

Product Information

No, oxygen free pure copper wire will not deliver any noticeable improvements in sound or power. It’s not worth spending more money on it.

A tape measure works well and so does string or rope you can place along the path where the wire will go. However, I’ve made it easy for you: You can use my speaker wire size calculator or speaker wire size chart sections provided below. SPEAKER WIRE GAUGE CALCULATOR It is based on its use. 12 gauge speaker wires are the best for long wire runs and high-power applications. Conclusion If you rarely use your amp or stereo output above 50%-60% power, you can go down one wire AWG gauge. This is because you’ll never reach the wire’s current capacity if you don’t use maximum power.You may have heard of the skin effect in some conductors which becomes more of an issue at higher frequencies but that’s well above the 20 to 20kHz audio range so it’s not something to worry about. Stranded speaker wire design

The current flows through two conductor sides (positive & negative) for a total of: 2*4m*0.0147Ω/m = 8m*0.0147Ω/m = 0.1176Ω total resistance for 4m of 19/29 stranded wire. Also, a 14 gauge speaker wire should be used to connect an 8-ohm speaker within a distance of up to 80 feet whereas a 16 gauge speaker wire should be used to connect an 8-ohm speaker within a distance of up to 48 feet. It’s a good compromise between price and power handling as it’s usually affordable and easy to find. How to find the correct size wire for ANY length or speaker system inductance, AC resistance due to skin effect (to a much smaller extent), will further increase these To get the same performance as true copper wire when buying CCA speaker wire, move up one gauge in size. For example, to replace 18 gauge copper wire, use a 16AWG or 14AWG CCA wire.

Speaker wire doesn’t have just one size (gauge) – it’s standardized and based on the American Wire Gauge (AWG) chart which lists standard sizes using a number.
