Floor Loudspeaker Reviews

A.C. Wente of Bell Telephone Labs was apparently the first person to get the bright idea (in the 1930s) of measuring sound transmission in a small room. A loudspeaker at one point reproducing pure tones of constant power, and a microphone at another point measuring sound-pressure levels, gave him the means to assess the room's impact on sound quality. The measured frequency response was so ragged that I'm positive the venturesome Dr. Wente was duly shocked.

There was no limo, just a walk filled with Christmas-in-Chinatown sights from the F train east down East Broadway, past 169 Bar, under the Manhattan Bridge, to the Dim Sum Palace. I was having a dinner meetup with an artist-writer friend named Joe who invited me to hear the wide-range AER drivers that he has bolted onto clear acrylic AER baffles with big, round, clear horns on the front.

I live in a house that has a pyramid-shaped roof, so I guess you could say that I have a thing for pyramids (footnote 1). That's probably why I was immediately drawn to the Green Mountain Audio Diamante. I'm also attracted to floorstanding speakers with small footprints, since my listening/video room is only 13' by 16'. My Holy Grail of loudspeakers is a small speaker that's flat between 20Hz and 20kHz, can do 110dB sound-pressure–levels without straining, and costs less than $1000/pair.

When a loudspeaker designer produces a world-class product, it is usually the result of years, perhaps decades, of experience gained from designing less ambitious products. To review a particular designer's product history is to witness the learning curve in action as both his skill and technology advance. Successfully battling the laws of physics to produce a truly exceptional loudspeaker is thus thought of as the domain of the seasoned veteran whose vast knowledge and experience culminate in the pinnacle of his career—a world-class loudspeaker. Moreover, it is just these designers, working their way up to their masterpiece, who are the most successful at getting an ambitious design right. The high-end loudspeaker business is littered with the remains of companies that attempted to build a first product far too lofty for their skills.

Paul">http://www.stereophile.com/interviews/117">Paul Hales does things differently. "I set out to build a true reference speaker," he asserted when I asked him about the, er, concept behind his Concept Five loudspeaker. For a mere six grand? The other guys don't even blink at $20k, $30k, even $70k statement speakers.

What's in a name? One of my favorite Rodrigues cartoons (footnote 1) shows a meeting of a loudspeaker manufacturer's marketing people, trying to come up with a name for the company's latest product:

Last July I reviewed the $4850/pair Hales System Two Signature loudspeakers and enthusiastically recommended them. In fact, they displaced the B&W 801 Matrix 2 as my reference loudspeaker, and have become a fixture in my listening room. Over the past seven months, my impressions of the Signatures have been largely confirmed: transparent and uncolored midrange, resolution of fine detail, precise imaging, superb transient abilities, and, most importantly, an ability to thoroughly involve the listener in the music. These qualities earned the Signature a Class A recommendation in Stereophile's "Recommended Components." I've greatly enjoyed the many hours spent with the Signatures.

Hales Audio makes another loudspeaker—the System Two reviewed here—that is very similar to the Signature, but much less expensive (footnote 1). Because the System Two is such a close relation to the Signature—it uses identical drivers, a nearly identical crossover, and similar cabinet construction—and costs nearly 2 kilobucks less, I was eager to hear what the smaller system had to offer. Because the Signature was recommendable at $4850, the System Two just might be a bargain at $3000 if it even came close to the Signature's musicality.
