    it's a test that a very anal tweaker came up with... other than testing speakers, it's basically useless for the average consumer.

    a double blind test was not invented up by an audio tweeker. They have been used for many many years to test pharmacueticals and other products where user bias is present.

    They allow objective measurements of a subjective test.

    In my opinion, if you want to say speaker X is 11ty billion times better than speaker Y, that is fine, if its in your opinion. Now, what if in reality, you couldnt differenciate the difference between the two speakers, and you were just saying that one speaker was better than the other because it looked nicer?

    A double blind test would take care of that. It can't prove what sounds BETTER, but it can prove if there is an audible difference or not.

    Here is a good description on how to setup a double blind test:

    I feel so strongly of double blind tests because they allow people to determine whether a new component, tweek or other addition to their audio systm is making any kind of audible difference. If you had a pair of 10,000 dollar speakers in front of you, that looked extremely nice, used beautiful speaker drivers and rare wood veneers, wouldnt you expect them to sound better than say a 400 dollar pair of speakers? What if you had a blindfold on, and had to pick which speaker was playing at which time? If you couldnt distinguish one from the other, would you really want to spend that 10,000 dollars on speakers? Maybe you would, but if you were judging your opinion on buying the speakers based on the way they sounded, wouldnt you be making a very poor buying decision?

    this is a well made point and I agree completely with it IF one was looking for a speaker or whatever based solely on accoustic response. Unfortunately aesthetics are a prevealant part of society so it basically wastes the point of a double blind test :hs:

    ...or reliablity. a profile coax might sound as good as a boston acoustics coax during this test, but it probally won't survive as long in the real world.

    Such tests are done to eliminate the aesthetics, and also the other intangibles, too. Passion unfortunately seems rule a lot of high-end audio theories, beliefs, and attitudes, while hard facts and plain and simple quality can take a back seat.

    You said "unfortunately aesthetics are a prevelant part..." If that's really unfortunate to you then I urge you to ignore such societal pressures and pursue audio components for just that: the audio.

    (This isn't to say I don't want my speakers, etc to look good... it just doesn't weigh in to the equation nearly as much as sonic accurracy and value.)
     
  7. Or perform a double blind test and go from there :)

    I'm with you on that, I would rather have some less than aesthetically appealling speakers that sound better, but after years in retail I've learned that the majority of people aren't comitted to that kind of fidelity. . .

    Very true. Before I thought you were speaking for yourself, not the majority.

    Ive heard of this been done to people when testing different grades of audio cable to see if their really was a difference in sound, none of the people in the group could tell the difference between the sound being run through high end audio cable or through a standard household coat hangor. lol
