Thiel Audio's CS3.7 loudspeaker was launched, to much fanfare, in 2006. Like most of Jim Thiel's designs, the CS3.7 received universal praise, but it was Jim's swan song. No one could predict that he would pass away in 2009, undoubtedly leaving on his desk many future designs.

But more was in the cards for—and from—Thiel Audio. The company was sold in 2012 to a private equity company based in Nashville; soon thereafter Thiel Audio moved to that city from Lexington, Kentucky, where Jim had co-founded it in 1977. Thiel's longtime president, Kathy Gornik, left, and for a while the company's directors came and went as if through a revolving door.

Boy, do we ever get letters. From readers angry that we review too many expensive products. From readers depressed that we review too many affordable products. From readers bemoaning our digital coverage. From readers asking when we're going to get with the 21st century and stop gushing over analog. From readers wanting more coverage of tube products. From readers wanting more coverage of MOSFET amplifiers designed for high voltage gain on the output stage.

The DQ-12 is the latest loudspeaker from Dahlquist employing their "Phased Array" technology, first used in 1973. The company was formed that year by Jon Dahlquist and Saul Marantz to produce the DQ-10, a loudspeaker that enjoyed a long and successful life. When I sold hi-fi in a retail store in the late 1970s—we stocked Dahlquist speakers—the DQ-10 was among the more prominent audiophile speakers, prized for its imaging abilities.

In 1976, Carl Marchisotto joined the company, designing support products for the DQ-10 including a subwoofer, variable low-pass filter, and a passive crossover. Jon Dahlquist is no longer actively involved with the company; Carl has now assumed the engineering responsibilities at Dahlquist and is the designer of the latest group of Phased Array loudspeakers (footnote 1). This new line, introduced at the Winter 1990 CES in Las Vegas, encompasses three models: the $850/pair DQ-8, the DQ-12 reviewed here, and the $2000/pair flagship, the DQ-20i.

Day One was press day, with only we ink-stained wretches (or at least the carpal-tunnel afflicted) invited to the party.

As I write these words in January 1991, we're right in the midst of an annual media feeding frenzy: the "Best of the Year" follies. This usually takes the form of lists compiled in groups of ten for reasons that must hearken back to some obscure Druidic practice. You know the routine: "Ten Best Books of the Year," "Ten Best Films of the Year," "Ten Top Personalities of the Year," "Ten Best Sports Plays of the Year." Every corner of the media seems eager to get into the act. Special-interest magazines are hardly immune. Car enthusiasts can get their fill of "Cars of the Year." Computer literates find their favorite rags full of the "Ten Best Computers/Computer Accessories/Computer Programs." And music magazines regale us with the "Ten Best Recordings of the Year." Everyone with access to a transmitter or printing press has got, it seems, a little list.

Audio journalists tend to wander the corridors of a CES in a minor state of shell-shock. There are no carnival-barkers outside the rooms enticing one to enter (not yet, at any rate), but the sounds and reputations oozing from the open doorways yield little to the "hurry, hurry, hurry" crowd. The Signet room has always, it seems, been one of the quieter oases, often eschewing sound altogether while contentedly displaying their phono cartridges, cables, and various accessories. On a recent CES hunt, I was therefore intrigued to find them demonstrating two new loudspeakers, of all things, to the milling throngs.
