New member Username: GaroLondonUK Post Number: 10 Registered: Aug-05 | Could anyone shed any light on the confusing world of speaker wire guage. I've recently bought some 2 x 2.5mm2 QED original wire to power a set of 6 olm speakers. All sources of information regarding recommended maximum lengths specifies wire size in AWG. Is there a method that i can find out what the AWG of my 2.5mm2 speaker cable is?? Thanks in advance |

Is this the case or am i confused!! Further to that, currently i am running 13 AWG wire for 5m on a 6 olm load, would you suggest this is not appropriate |

Silver Member Username: Timn8terSeattle, WA USA Post Number: 505 Registered: Dec-03 | That doesn't sound right to me. The thicker the wire the less resistance. I didn't see that reference in the article you posted although I haven't taken time to read the whole thing. 13 AWG for a 5m run with 6 ohm speakers should be just fine. |

Bronze Member Username: GaroLondonUK Post Number: 12 Registered: Aug-05 | It doesn't explicitly state that fact, but what the "wire table" does show is that as the AWG gets smaller, (from 22AWG to 10AWG, the recommended maximum lengths go from 3 feet to 50 feet respectivley (at 2 olms for arguements sake. I believe i'm right in saying that a 22awg is a thicker wire than a 10awg Has this table got any credibility at all as it seems it defies the laws of physics?? |

Before asking for a reason why this is so, you would be better off calling your local telephone service provider and asking why you pay "local service taxes" and where the money goes. By the time you get that answer, wire guage will be a piece of cake to understand. |

In sound, an increase of 3 dB requires a doubling of power. In wire, a decrease of 3 units doubles the area. So a single 12 AWG wire has as much cross-sectional area as 4 wire of size 18 AWG. |
