What Gauge Wire Should I Use?
Choosing the right size gauge of speaker wire depends on how long the length of the wire is from receiver/amp to speaker. Please see below for a table graphic that breaks down the maximum length of wire for each gauge size.
|Wire Gauge||4 Ohms||6 Ohms||8 Ohms||70 Volts|
|22||6 feet||9 feet||12 feet||321 feet|
|20||10 feet||15 feet||20 feet||518 feet|
|18||16 feet||24 feet||32 feet||823 feet|
|16||24 feet||36 feet||48 feet||1305 feet|
|14||40 feet||60 feet||80 feet||2127 feet|
|12||60 feet||90 feet||120 feet||3376 feet|
|10||100 feet||150 feet||200 feet||5377 feet|
The 8 Ohms column is highlighted due to essentially all of Klipsch speakers having a nominal impedance of 8 Ohms. Please note that AWG = American Wire Gauge, which is the US standard measure for the diameter of electrical conductors
The table above shows gauges of wire and the maximum length that it can handle based on the impedance of the speaker. For instance, a 22 gauge wire connected to an 8 Ohms speaker should not exceed more than 12 feet in length from amp/receiver to speaker.
In addition, a 16 gauge wire connected to an 8 Ohms speaker should not exceed more 48 feet in length from amp/receiver to speaker.
If you have a wire that exceeds it's recommended length, you will start degrading the audio signal's volume and overall quality. It is always recommended to be conscious of how large the wire gauge needs to be based on the lengths listed in the table above.
