![]() ![]() ![]() For runs over 30 feet, definitely 14ga and 12ga wire is preferred. For runs over 20 feet to 30 feet, 16 ga wire is preferred. Generally, (USA) 18 ga wire is adequate and uneffected for runs up to about 15ft to 20ft. But, by the same token, 3 or 4 feet on one side and 25 or 30 feet on the other front side is too great a contrast. If you are using a moderately powered amp, and 6 or 8 ohm speakers, and 16ga or 14ga wire, then under some circumstances, 1 meter on one front side and 3 meters on the other front side wouldn't be unacceptable. Four ohm and 2 ohms loads would be considered Low Impedance. High power means 200 REAL watts or higher. Moderate power means 50 REAL watts to say 150 watts. However, for low impedance speakers and/or for exceptionally high powered amps, (USA) 14ga and even 12ga wire is preferred. ![]() USA 16 ga wire is more ideal and more common. USA 18 ga wire for short runs with moderate power amps, is fine. But, you really shouldn't be using wire that small. If you are using (USA) 20 gauge wire or smaller then you certainly should keep them equal length and hopefully reasonably short. That said, it depends on the gauge of wire. (I routinely use asymmetrical lengths of even smaller gauge 12AWG cables without concern.Left Channel and Right Channel lengths should generally be the same, but Front Channel and Back Channel do not have to match.įor example, 1 Meter to the Left and Right Front Channels, and 10 Meters to the Left Rear and the Right Rear Channel satisfies the requirement. Assuming connectors are clean, good contacts, I bet you won't hear anything of concern. )īest is just to borrow them and have a listen for yourself. You're not going to be able to hear a difference of this microscopic magnitude with a signal velocity close to the speed of light. Assuming conservatively that your speakers are a 4Ω load, this means that the longer cable would have a -0.0059dB attenuation compared to the other side. For a 0.8m length difference, this means it's 2.7mΩ difference if not less between the 2 cables. The Zef Max Speaker Cable according to the web page is ~10AWG pure copper for it's "central core". If anything it is the resistance that is most important for speaker cables. Not that these picofarads and microhenries matter when we're looking at only 3m (10') within audio frequencies. Given the design, looks like this is lower capacitance cable with slightly higher inductance if we were to measure it. Click to expand.No, don't worry about it. ![]()
