Floor Loudspeaker Reviews

The Model R107 represents the flagship of KEF's Reference Series, and is second only to the Professional Series KM-1 in KEF's product line. Anatomically, the 107 resembles a person. Beneath a decorative "hat," there's a special head assembly akin to the head on the old Model R105. This head assembly contains the brains of the 107, namely a T33 ferrofluid-cooled tweeter and an improved version of the classic B110 midrange driver, featuring a better voice-coil and a new polypropylene cone. The nerve center is also here, in the form of two passive dividing networks and load-impedance equalizing network. Level equalization of the drivers is performed actively within the KUBE, the second brain of the 107—about which you'll hear more shortly.

In this age of $70,000-plus "flagship" designs, perhaps $25k is no longer an obscene amount to pay for a pair of loudspeakers. Still, it's mucho dinero. What makes a speaker worth this kind of bread? Does the product's intrinsic value really warrant such a lofty cost, or is it merely a matter of pricing at what the market will bear? The answers to these questions requires careful examination of not only the speaker, but also of the buyer's own soul, priorities, and pocketbook.

I've never heard a pair of the Italian Sonus Faber speakers I didn't like. What I've never liked was the US price: too high. And then you have to put them on costly stands. Plus, you're paying a premium for the magnificent woodworking and exquisite design—something I wasn't into, since I live with my stereo in a basement office/workshop/listening room some (who shall remain nameless) refer to as the "habitat for inhumanity."

A reviewer's life is not all fame and fortune. There are downsides, too, one of which is that, while many great-sounding components pass through your listening room, only a few get to stay there on anything like a permanent basis. (And that involves money changing hands, as in [gasp!] "purchase.") Before I bought my long-term reference loudspeakers—a pair of B&W John Bowers Silver Signatures—back in 1994, the speakers that had spent the most time in my 2900-cubic foot listening room were a pair of Thiel CS2 2s. I reviewed the '2 2 in the January 1993 issue of Stereophile (Vol.16 No.1), and although it was relatively affordable ($2250/pair at the time of the review), it did most of what I wanted a speaker to do. Other than a limited dynamic range in the bottom audio octave and a slightly exaggerated top octave, the CS2 2 sounded effortlessly smooth and free from coloration throughout the midrange and treble. It was also a real imaging champ.

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:

"Danes are boring," Dynaudio US's president Al Filippelli said. "Let's face it: They work hard, they tell the truth, they give full measure in deals, and they don't embroider. What you see is what you get."

Audio Artistry's Beethoven is the banner model of the company's Composer series (footnote 1), which includes the entry-level Vivaldi as well as the Dvorak I reviewed in the April 1996 Stereophile (Vol.19 No.4, p.204). Like the Dvorak, the Beethoven is a four-piece, bi-amplified, dynamic dipole design; unlike the Dvorak, the Beethoven has been taken to the nth degree of refinement.
