Practical advice on speaker cables please ?
I'm aware of the never ending discussion on interconnects and speaker
cables, but I just want some advice on what to actually buy. Nominal impedance of speakers is 6 ohms. Room is quite large and so amp/speaker distance will be 4-5 meters. Speakers are bi-wired. I just need an idea of cross-sectional area and where I can get some suitable cable. I'm not convinced by the talk of OFC and so on. Multistranded copper of sufficient thickness is fine by me. Suggestions please ? Jo |

You are right, there is much rubbish spoken and snake oil out there, but given that you have a fairly long run then thicker cable is best so that it doesn't become significant in the damping factor of the speaker/amp interface.

I use that on my Tannoy R2/NAD320i; no problems at all. YMMV, Folkert/NL |

I'm not convinced by the talk of OFC and so on. Multistranded copper of sufficient thickness is fine by me. Suggestions please ? Jo Before I went over to active 'speakers, I have used two cables:- QED 79 strand is inexpensive and goes into a banana plug easily. It also solders well if you want to attach it to spade terminals, or just tin the ends. The second cable I have used is 30 amp car wiring cable. Available in several colours, I took two lengths of red and black cable and twisted them together using a hand-drill. As with the QED cable, it solders well, and, if these things matter, had an interesting "technical" look about it. I did once try one of the woven high-capacitance cables, as I got it very cheap, but some amplifiers (Naim for instance) get upset by the high capacitance, so it's not of universal application. Ordinary ring-main cable works well technically, but it is stiff and difficult to get to lie flat. By the way, unless you have a specific reason for doing so, bi-wiring is only a way of getting more copper between your amplifier and 'speakers. It won't be necessary if the cables are thick enough, even over the 4-5 metre length you're using. S. |

I did some rough calcs and came up with a figure of 3-4 sq mm and was curious about what the experts here suggested. Jo It is nothing to do with the speaker load impedence, rather the amp output impedence. When the loudspeaker cone is extended by signal, if the signal is removed then it is down to the mechanics of the cone mount to return it to its rest position - except that it won't, it will follow a decaying oscillation path. During this time, as the voicecoil is now being moved mechanically in a magnetic field it becomes a generator, so the lower the load that it sees - in this case the output impedence of the amp plus cable resistance - the quicker the energy will be dissipated. As an amp output impedence is typically around 0.1R (or less sometimes) then the resistance of a thinner cable can become significant, hence why thick is better. I used to have a pair of BIG transmission line loudspeakers that could rattle windows at 10 paces with only a few watts! I used 6mm power cable used in the mobile radio industry (where I work) and they were more than happy. When we moved to this house I initially couldn't get under the floor to run the bigger cables so I ran some 0.75mm mains cable - and the sound was AWFUL!! Bloated flabby bass with considerable loss of LF detail (amongst other things we like pipe organ music, the penalty of having a father-in-law who is an organist!) When I fitted the thicker cable normality was restored. -- Woody harrogate3 at ntlworld dot com |

It follows that the cable resistance should be low compared to the *speaker* impedance because it is this that has the major effect on the overall output circuit energy dissipation and hence damping factor. I see the setup as being analogous to a generator with a short circuit on the output terminals, or a very low resistance load. The windings of the generator heat up and dissipate more energy than the load.

Maplin are currently doing a multistrand cable with a csa of 5.28 mm sq that is advertised as "HiFi", OFC and all the hype, but at £1.49 /m looks as cheap as some similar power cables. Jo |

It's about power dissipation - and FR imbalances because the speaker is designed to be driven from a low impedance. -- Stewart Pinkerton | Music is Art - Audio is Engineering |

The problem with 'cable impedances' for speakers isn't really due to need for 'damping' the mechanical resonance of the driver, for the reason you explain. The electrical losses tend to be dominated by the actual speaker resistance. The problem is that most loudspeakers have an impedance that varies with frequency. The amp+cable impedances then act with the speaker impedance to make a frequency-dependent attenuator, and may alter the frequency response - usually by a slight amount.

This should be between 1 and 2 % of your minimum speaker impedance, so not a problem by any measure. -- Stewart Pinkerton | Music is Art - Audio is Engineering |

I've done blind testing with £1000+ cable sets and standard 2.5mm^2 flexible cable and never once found an individual who could tell the difference, but when they could see the exclusively wound cables in their silk sheaths it was a completely different matter. On the other hand I've had to dye my hair pink after a bet and a blind test involving some foam like pads that went between a pair of Grand Coup`e's (how do you make that apostrophe thingy on a UK keyboard?) and sand filled Soundstyle stands. So I guess the pendulum swings both ways and all that business.. // J |

It certainly isn't bell wire. What I replaced with it was some ancient figure of eight two core mains cable with transparent plastic insulation, the sort of thing that might have been used on a table lamp a few decades ago (and probably was). The copper in the loudspeaker cable was visibly thicker than this table lamp wire I'd been using for years, yet in all honestly I cannot say I noticed any difference whatsoever. Rod. |

I'm not convinced by the talk of OFC and so on. Multistranded copper of sufficient thickness is fine by me. Suggestions please ? Gale XL-105, 69p/metre at Richer Sounds. Or if you need lots, you can get the same stuff at CPC for about £20 for a 100m roll (different name on it, same cable as far as I can tell). Nice and flexible, doesn't sound bad either. I googled on Gale XL-105 and one of the web sites said this: ------------------ However, it does have a rather raw quality with some programme material, and there is a sense akin to stasis at times. Music simply goes through the motions, but somehow nothing much seems to happen, and imagery stays firmly locked into the speaker enclosures. It also sounds rather grainy at times. --------------------- Which was rather typical of most websites I visited, even Gales themselves. Significantly, among all of the lurid prose few of the websites mention the most important parameter, ohms/meter. And even if this is somewhat high on a long wiring run, how could anybody possibly hear the "raw quality" described ? I'm wondering if I should set up a business selling gold plated mains cables with 13A plugs to the more gullible members of the hifi fraternity for £99.99 a throw? Obviously, I would need to do a course on creative writing first :-) Jo Incatech already did that! So did Russ Andrews! Heck, I remember him when he was a simple sales droid in Hi-Fi Corner in Edinburgh. Who eleveated him to guru status? -- Stewart Pinkerton | Music is Art - Audio is Engineering |
