LOL My money is on Keith... Personally, I have 15 Ft runs of 10 AWG wire, even though one speaker is only a foot away and the other about 8 ft away. I keep them equal lengths even though the difference in resistance would not make an audible difference. It simply gives me more flexibility with placement if I require it later. So why the 10 AWG? 'Cause it looks nice! I could have easily used 18 AWG, but skinny wires are as unattractive as really skinny women!  Be careful of applying that strategy in reverse View AttachmentWow! She must be 4/0!!! |

Hi David Sorry, it's not the right way to go. The amplifier sets the cable's characteristics, not the speaker. Trust me n EMOTIVA's amplification, a 12-14 AWG doesn't cut it. You need better. Bose has a nice marketing, but not so nice products. The 901 was a hit in 1977...Since, 5 generations and not much shanged. Not my cup of tea. So, please do share the formula you use to calculate required size. I am sure many of us would love to see it, Mark Hi Mark I assume this is pointed to me. I would rather keep this knowladge with myself for now. However, I'll do the calc. for you. Tell me what amplifier and speakers you use, the desired length, and I'll tell you what AWG would do. I may also give you a quote for such a cable, if you would like to have one. Please send your data to my e-mail: lang_m@012.net.il |

Those who know even less - are doing QA. Are you in the mood to show us what someone who really doesn't know (or understands this subject) reacts like? Sorry. I thought this site is respectful. |

Yep..... A standard for decades based on the correct math. Bill No math and no calc. This table is so wrong! who goes with speaker cables 200ft.? Same is the site: www.roger-russell.com/wire/wire.htmIt doesn't tells you anything that would help you figure out what is the right cable you need. A lot of words that are practically about nothing! Whatever you like it, or not, this subject (Speaker Cables) never got the attention. Many came up with crap stuff, shooting in the dark. In such a chaos, many firms took advantage to go banana and sale unbelivable urban legends for a fortune. It is time to get back to the drawing board and put the facts on the table. |

Mark (PS - short of seeing a formula or you laying out the fundamentals clear enough for others to understand, I stand with the others who have quoted numerous experts on the topic. And, FYI, I used to use ~4' long cables that ran from monoblocks to my speakers. Each terminal had dual 10 gauge wires, for an effective 7 gauge. I switched to thinner and longer wires and heard 0 difference.) |

Mark Hi Mark I need the data sheet of the Hypex nCore. They make D-class modules as I've seen, that you put together? I asked: Tell me what amplifier and speakers you use, the desired length. Please tell me how close can you put the monoblock amps to your Magnepan 1.7's Thanks Michael |

I switched to thinner and longer wires and heard 0 difference.) Hi Good for you. 1. Most guys here had cables way longer than 4'. As the formula of cooper cable resistance is: R = ρ x L/S (L is in meters and S is in mm2. ρ is coopers conductivity k). So as L goes 3-6 times shorter, so can go the cable thickness. cooper: 1.68x10-8 @ 10 deg C. 2. There is a relative affectivity when you reach a certain resistance (the optimal resistance), when the cable can get lower in R (resistance) but it won't do any better. I think that you were there, even no data on your equipment was provided. If you would be kind enough to provide that information, I could tel you what is that optimal length vs thickness you need. Your assumption that the thicker and shorter will go better would work till you reach a certain resistance (low). Afterwords, it will have no audiable effect. Especially for those (and I said it loud and clear) that use monoblocks, can save big on cables, as they can be placed relatively close to the speakers. On top, if you were using tube amplifiers (or similar) you could use maybe a line phone cord and would do... Michael |

How did you ended up with this product, that has no information as the audio std. requires: THD, SNR, DF etc'. Could you come up with somthing? Thanks Michael |

Please let me know what math you feel Roger Russel (and indeed the ANSI, CEA and NEC) have wrong about speaker cables? Please describe to me, an MSEE, how your theory on speaker cables is so much more correct than all conventional science? |

DF @ 8 ohms, 1KHz The output impedance for a Hypex Ncore @ 1KHz is 1.5 mohms, so into an 8-ohm load that calculates to DF = 5333.333. DF is perhaps the most meaningless spec in audio. Why do you need that to calculate speaker wire size required for a 500 watt amplifier? |
