Has anybody done blind tests on speakers or there any articles on blind testing speakers?
Now, before you ask what I'm talking about, I'm not asking for blind testing to show that all speakers sound the same. I'm wondering if blind testing has been done to see what speakers people prefer. As with every other line of products for sale in this world, the general rule seems to be that people perceive more expensive products as better. In the case of speakers, expensive speakers are "obviously" better than less expensive speakers.
In audiophile world, a more expensive speaker would have better clarity, soundstage, it would reveal details less expensive speakers could not, etc.Have there been blind tests supporting such statement one way or the other?

4) There were clear correlations between listeners’loudspeaker preferences and a set of acoustic anechoicmeasurements. The most preferred loudspeakers had thesmoothest, flattest, and most extended frequencyresponses maintained uniformly off axis.
What exactly is smooth? It sounds like an audiophile term. Does it mean that the frequency response looks smooth (without jagged changes?).
I'm not very knowledgeable on studio monitors, but the conclusion in the JAES article seems to support the idea that studio monitors have been getting it right all along. Is this statement correct?

Is this statement correct?Just from reading the posts, and not from any real knowledge, but it looks like the clause "maintained uniformly off axis" is a point where near-field monitors, at least, needn't try too hard, so making it easier to hit the other desiderata.
So, it's not audiophile terminology... Its something normal people (including engineers and scientists) can understand!
And even as far as smooth frequency response goes, studio monitors by no means have been getting it right 'all along'. Some have been notorious for coloring the sound.
The JAES (Journal of the Audio Engineering Society) has a series of articles from Floyd Toole and Sean Olive, from the past 20 years, that does just that -- explored the factors that determine speaker preferences. Plenty of blind tests involved.

Thanks for the links to JAES and the article. I'll print it off so I can read it.I also found this on the PSB Speaker website. PSB Speakers blind testingIt's an short but interesting piece. To quote the end."We designed it for a flat frequency response [in which no particular frequency range – bass, midrange, or treble – is emphasized] in the anechoic chamber. But thanks to blind testing, we realized that a perfectly flat response sounds a little too bright in an actual room. So we toned down the response a little in the 5 kilohertz [treble] range, and right away it became a winner. If you don’t do this kind of testing, you’ll probably never uncover those kinds of flaws.”
