Speaker wire is it science or psychology

It is hard to say what gauge wire because this magizine comes from the UK and they use mm2 to determine what we call gauge. Most of the wires used it does not tell gauge and also it is hard to make out how long the cables where(it is shown in a smallish box entitled Fig. (3) Test Set up) but if I had to guess on what I can see I would say 5.6m. Most of the cables sort of spiked at 1.00k or so and sort of tapered off toward 11.0k some nearly vanishing off of the graph before the 11.0k mark and some had wierd peaks and valleys. I hope this answers your question a little bit also there are some references listed you may be interested in looking into them:
1.)"The Essex Echo" by Malcolm Hawksford found HFN/RR, Aug '85, Oct '86 and Feb '87
2.)"Speaker cables: Case proven" by Ben Duncan, Proc. Institute of Acoustics, Nov 1995 Also published in Studio Sound (UK) and Stereophile (USA), Dec 1995
3.)"Effects of cable, loudspeaker and amplifier interactions", By Fred E Davies, JAES June 1991
4.)"Black Box" by Ben Duncan, HFN/RR, March 1996
5.)The Genesis Report, QED. tel 01276 451166 this document is low on rigour and is filled with punctuation and spelling errors, but contain creative ideas on demonstrating cable effects.

I hope this will help you on your quest for the "Truth"

tireguy - I ordered the article, however, they are saying 3 to 4 weeks, ugh. I am, of course, naturally suspicious. I have never heard the term "dynamic suppression".

I am gathering test gear for a speaker project I have in mind and I realized something this morning. With just an amp, a scope and an audio generator I can do a very accurate measurement of wire. I will go down to Radio Shack and get some of the wire everyone hates and I always use - their cheapest 14 guage speaker wire. Using 10ft of this vile stuff, I will connect it to a speaker placed on the test bench. The audio generator will drive the amp, of course. The scope is a dual trace and I will display the voltage at the amp on one trace and the voltage at the speaker on the other trace. The traces can the be position directly over each other on the scope. The beauty of this simple setup is that it is not dependent on the frequency response of the generator or the amplifier. All I have to do is to find a difference. I can even test the scope by switching leads. If I do find a difference, well, I have my wife's 38 revolver here so I can do the honorable thing. What do you think?

The article Tireguy pointed out from HiFi News... is the article I was referring to.

I take it, Redkiwi, that you cannot answer the question.

Trelja - See my post to tireguy. I am waiting on the delivery of the signal generator.
