I couldn't resist posting one more photo of Bruce Thigpen's fan-driven infrasonic subwoofer, this time showing the drive-unit in operation. Loaded with an infinite baffle—it is in the next room—it fires into a foam-lined sub-chamber, which low-pass filters the residual fan noise, leaving just the awesome infrasonics to pressurize the room next door. Because the fan is providing the main motive power, just 30W of audio signal was required to create an spl of 115dB at 8Hz!

Sad news this week: We heard from Ken Kessler of the passing of legendary UK engineer Stanley Kelly, who died in his sleep on November 13, after suffering a stroke the previous week. Stan would have been 89 next month. While he was, of course, the "Kelly" of the classic Kelly Ribbon Tweeter, he was also one of the founders of Hi-Fi News and was the only person to have been listed on the English magazine's masthead since Vol.1 No.1, the June 1956 issue. In recent years, Stan had developed a series of high-sensitivity speakers for UK manufacturer Musical Fidelity.

Stax Kogyo, a small audio company by Japanese standards, has been for the past 15 years steadfastly refining and redefining the electrostatic headphone. The SR-Lambda Pro is their current flagship model, and at a 1984 US list price of $780 it also represents a very substantial investment in headphone technology.

Steinway-Lyngdorf's S-Series loudspeaker is tiny, at just 10.2" H by 7.8" W and 3.1" D. (My apologies for the grainy photo but the battery in my camera gave out and I had to resort to my iPhone 3GS for this shot.)

After Peter Lyngdorf left Tact, he went into partnership with the Steinway piano company to make a line of expensive speakers aimed not at audiophiles but at well-heeled music lovers. I was impressed by what I heard of the first of this line, which incorporates Lyngdorf's RoomPerfect acoustic correction, when I auditioned it in Manhattan a couple of years back, so I wasn't surprised when Steve Guttenberg button-holed me and told to go listen in the Steinway–Lyngdorf room at Axpona.

The S-Series subwoofer-satellite system ($22,100) was producing a big sound with the tiny satellites stood on a credenza against the wall behind them. Incorporating RoomPerfect correction, the speakers also use digital signal processing to produce a flat response, which Peter Lyngdorf explained allowed him to optimize the drive-units for maximum sensitivity. The two small subwoofers were placed in the room corners, with a crossover frequency (depending on the room correction necessary) around 200Hz

The accuracy of a hi-fi system's "soundstage" reproduction seems to be of paramount importance these days, just as a component must now have "transparency" to possess hi-fi righteousness. If the system in which that component is used doesn't give good soundstage, then the system's owner has definitely fallen by the wayside. But what defines a good soundstage? Stereo imaging must have something to do with it, I hear you all cry. (I would have said stereo imagery until Larry Archibald pointed out that imagery has far less to do with hi-fi than with good writing, something I'm sure we agree has no place in a hi-fi magazine.) OK, what defines good stereo imaging?

The people at Manhattan high-end audio retailer Stereo Exchange know how to throw a party. They proved it back in April with their Spring Fever event, and they look to surpass the success of that outstanding evening with their 25th Anniversary Celebration, this Thursday, November 5, from 3–9pm.

Stereophile's senior contributing editor, Michael Fremer, and the magazine's editor at large, Art Dudley, are both giving presentations this spring at Cornell University in Ithaca, NY. Michael appears on Tuesday, March 28, followed two weeks later, on April 11, by Art Dudley.

"You're only as good as your most recent gig," was literally drummed into me in my pro musician days; I've found it to be just as true in magazine publishing. No matter how much hard work went into, say, an equipment review, a couple of months down the line that review will be as fresh as yesterday's undunked donut. And no matter how good-sounding the product, or how much it excited the writer, it will always tend to be overshadowed by the latest and greatest products written about in the new issue—the "moving finger, having writ..." syndrome.

There is a tendency in magazine publishing to concentrate on the present. Writers generally downplay what happened in the irretrievable past as being of lesser importance compared with the new and exciting, their enthusiasm pretty much tied to the ever-in-motion time-line. I instituted Stereophile's annual "Products of the Year" feature, therefore, to give recognition to those components that had proved capable of giving pleasure beyond the formal review period. To confound confusion, there are just five individual categories: "Loudspeakers" (including subwoofers); "Amplification Components" (preamplifiers, power amplifiers, etc.); "Digital Sources" (CD players, transports, D/A processors); "Analog Sources" (phono cartridges, turntables, tonearms, FM tuners, etc.); and "Accessories" (everything else).
