JA on Loudspeaker Measurements

Author's Note: Although I started accompanying Stereophile's loudspeaker reviews with measurements soon after I joined the magazine in 1986, it wasn't until 1989, when we acquired an Audio Precision System One electronics analyzer and the then-new MLSSA speaker measurement system from DRA Labs, that I developed the standardized data presentation that is still featured in our reviews more than three decades later. In this article from October 1991, I summarize the results from the first two years of using MLSSA to test 69 loudspeakers.—John Atkinson

The Stereo Image

For most people the terms hi-fi and stereo are synonymous, and yet it is clear that there is still a great deal of confusion over what the word "stereo" actually means. There isn't even a consensus of opinion amongst producers of records, designers of hi-fi equipment, audio critics and music lovers as to the purpose of stereo, and considering that the arguments show no sign of diminishing in intensity, it is instructive to realise that 1981 sees both the 100th anniversary of Clement Ader's first stereo experiments and the 50th anniversary of Alan Blumlein's classic patent on stereo.

Listening Tests and Absolute Phase

The problem confronting the magazine reviewer when organising the necessary listening tests to accompany/reinforce the measured behavior of a device under test is complex. There has never been a problem with the measurement aspect; as long as someone has access to the same test gear—and full knowledge of the test conditions—then he should be able to replicate the critic's findings exactly (assuming an infinitely narrow spread of behaviour from sample to sample—a rasher assumption with some manufacturers' equipment than of others). However, when it comes to determining reliably the audible (or inaudible?) effects on music program by an amplifier/cartridge/loudspeaker etc. then the going gets tough.

The Holy Trinity

In an e-mail exchange with Stephen Mejias about why the mere mention of cassette decks on www.stereophile.com can so easily inflame our readers (and John Atkinson), I began to develop the idea that the brains of audiophiles and music lovers are governed by three complementary needs, or desires, that define who we are. I joked to SM that these desires, which apparently shift over time, constitute the Holy Trinity of Audiophiledom. They are, respectively, the love, desire, and need for:

Chasing Rainbows

There was a time, very recently in terms of human history, when high fidelity promised to free the music lover from the constraints of the concert hall and the local repertoire, allowing him to choose at his whim any orchestra in the world playing any work he desired under the baton of any conductor he preferred. "All the pleasure of concert-hall listening, in the comfort of your home," was the way one display advertisement painted this musical utopia which, only 20 years ago, seemed right around the corner.

Who Are You?

In the four years since our last readership survey, Stereophile's circulation has grown by one third, from 45,000 to over 60,000 (footnote 1). We thought it time, therefore, to commission new numbers, from specialists Mediamark Research Inc. (footnote 2). Table 1 shows the demographic breakdown of the magazine's readers. While the launch of CD did bring more women into the audiophile fold almost 10 years ago, the proportion of Stereophile's female readers has not changed since 1988, at just over 1% (footnote 3). At one of the panel sessions at the 1992 High End Hi-Fi Show in Los Angeles, a man in the audience asked why high-end audio was so testosterone-bound when women were just as interested in music as men? The answers given by some of the many women at the show ranged from the fact that women only earn 47 cents on the dollar compared with men to conjecture that women are turned off by the hobby's tweak aspect. Certainly dealer Andrew Singer felt last October (footnote 4) that the high-end industry is hobbling itself by ignoring half the US's population.

Glory Days

The drive home from Montreal and the Salon Son & Image show is smooth and uneventful. The snow kindly stops just as John Atkinson and I climb into his Land Cruiser, the woman at Customs lets us into the US with little fanfare, and, there isn't much to set the heart racing. Every fifty or so miles, the highway's long dividing guardrail is punctuated by some enormous brown bird—a once majestic body that owned the sky is now slung awkwardly and pitifully over cold steel. It's sad that something so beautiful and strong can die so quietly. But quiet abounds out here. The sky seems to move nearly as fast as we do, clouds cling to tall mountains, and winds tug at the Cruiser's tires.

Are You a Sharpener or a Leveler?

A psychological theory (footnote 1) that I've always been fond of is the one that proposes the perceptual/personality dimension of Sharpening vs Leveling. As defined by the early Gestalt psychologists, Sharpening is an exaggeration of differences, Leveling a minimization of differences. In visual-perception research on this topic, when test subjects were presented with an asymmetrical figure, some later recalled it in ways that exaggerated the figure's asymmetry (Sharpeners), while others minimized or eliminated it (Levelers).
