Floor Loudspeaker Reviews

The Wilson Audio Specialties Alexandra XLF costs $200,000/pair. So does a Ferrari. Perhaps if Wilson Audio Specialties sold as many pairs of XLFs as Ferrari sells cars, the price might drop. For now, $200,000 is what you pay.

Can a loudspeaker possibly be worth that much? Add $10,000 for speaker cables, and that's what I paid for my first home in 1992. Today, the average American home costs around $272,000, which is likely less than the cost of an audio system built around a pair of Alexandra XLFs.

Loudspeakers have been commercially available for nearly a century, yet those whose drive-units are mounted to baffles of intentionally limited width didn't appear in significant numbers until the 1980s. That seems a bit strange, given that the technology to transform large boards into smaller boards has existed since the Neolithic era.

A highlight for me of Stereophile's 2011 equipment reviews was Kalman Rubinson's report on Sony's SS-AR1 loudspeaker in July. I had been impressed by this unassuming-looking floorstander at the 2009 Rocky Mountain Audio Fest, when, courtesy Ray Kimber, I had used a pair for my "Loudness Wars" demonstration—and was equally impressed when I used another pair for a dem of my recordings at Massachusetts retailer Goodwin's High End, in summer 2011. The SS-AR1 costs $27,000/pair and combines a full frequency range with an uncolored, detailed midrange, sweet-balanced highs, and excellent dynamics. "The Sony SS-AR1 is an impressive loudspeaker," summed up Dr. Kal; "it brings the analytical capabilities of studio monitoring to the listening room." So when I learned that Sony had introduced a smaller, less-expensive version, the SS-AR2 ($20,000/pair), it took me less than the proverbial New York minute to request a pair for review.

One of my formative audiophile experiences was the first time I heard electrostatic speakers. I walked into an audio store and heard music played by a live jazz combo. But where were the musicians? I saw none, though I did notice a couple of room-divider panels in the part of the store where the music seemed to be coming from. Eventually, it dawned on me that these must be loudspeakers—but they sounded like no other speakers I'd ever heard, and nothing like the Advents I had at home.

We've all read about how bookstores, appliance stores, and other bricks-and-mortar retailers are suffering with the increasing domination of Internet sales. That got me thinking about audio dealers. I've always believed that one can't really make an informed purchase of audiophile equipment without hearing it in a system properly set up by and at at a serious audio retailer. Here in New York City, we're blessed with six first-rate audio dealers in Manhattan alone, with more in the suburbs. I estimate that 90% of the products reviewed in Stereophile can be auditioned at a dealer or two within a two-hour drive of anywhere in the New York metropolitan area.

The phenomenon of the "singing flame" has been known since the 19th century. Place electrodes either side of a flame and, if you apply a high enough audio-modulated voltage to those electrodes, the ionized particles in the flame will cause it to emit sound. (Search YouTube for "singing flame" and you'll find many examples.) This principle was developed into a practical loudspeaker in 1946 by a French inventor, Siegfried Klein, who confined an RF-modulated arc to a small quartz tube, coupled it to a horn, and called the resulting speaker the Ionophone. An intense radio-frequency electrical field ionizes the air between inner and outer electrodes to produce a distinctive, violet-tinged yellow flame in the quartz combustion chamber. When the RF field is modulated by the audio signal, this causes the almost massless ionized flame to expand and contract in what should be a perfectly pistonic manner.

In March 2006 I wrote a very favorable review of Monitor Audio's Silver RS6 loudspeaker. At the time, I felt this $999/pair, small-footprint floorstander produced the greatest sound quality per dollar of any speaker I'd heard. Despite the proliferation of affordable speakers of increasing quality I've heard since then, I remained particularly impressed by the Silver RS6's clarity and lack of coloration and the speed of its midbass, all of which continued to exceed the performance of any other affordable speaker I've heard.
