Floor Loudspeaker Reviews

Keith Aschenbrenner, proprietor of Auditorium 23, based in Frankfurt, Germany, has long been associated with the people and products of Shindo Laboratory: From the early 1990s until the EU's 2006 implementation of the RoHS 1 regulation, which banned the sale of various old-style electrolytic materials—and thus most of Shindo's products—Auditorium 23 was the brand's European distributor and, arguably, one of its most empathetic and enthusiastic retailers worldwide. Throughout that time, and continuing through to today, Aschenbrenner has also worked as a designer and manufacturer of Shindo-friendly ancillaries and loudspeakers.

Monitor Audio's Platinum PL300 II loudspeakers weigh 120 lbs each, and my listening room is on the second floor, but I was spared the heavy lifting. The speakers were delivered by Sheldon Ginn, Jeffrey Ginn, and Jamie Arseneau—respectively, the VP of Sales and Marketing, Account Manager, and Service Manager of Kevro International, Monitor Audio's North American distributor. We set up the PL300 IIs, ensuring that the distance from each speaker to my listening seat was the same, then optimized the toe-in: the speakers ended up almost directly facing the listener position, close to where I'd had Wilson Audio's Sabrinas.

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.

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.

My lifestyle consultant warned me not to review Zu Audio's Soul Supreme loudspeaker ($4500/pair).

"Why not?" I asked. "They're exciting and super-enjoyable."

"Zu speakers are not mainstream," he explained. "People either love them or hate them. They're for music lovers, not audiophiles."

"That's not true!" I whined like a disappointed child. "They play Nina Simone and Aretha Franklin with spooky soul and natural tone! They play big classical orchestras—especially with trumpets and timpani—with radical ease and full-tilt momentum! And . . . and . . . they project large soundstages! Isn't that what audiophiles like?"

Marten is a small Swedish loudspeaker manufacturer with great aspirations, some of which the company has largely met. Leif Mårten Olofsson founded Marten and designs the speakers, while brother Jörgen Olofsson runs the business as CEO—a division of creative and administrative labors similar to the working relationship between David and Norman Chesky, the founders of Chesky Records and HDtracks.

Driving the Model Sevens at the 2014 CES were Vandersteen's then-new M7-HPA monoblocks, which provide a high-pass–filtered output (above 100Hz) to the upper-frequency drive-units of the Model Seven. At the time, I made a note to myself that I would like one day to try these amplifiers with the Sevens in my own room. That opportunity came later rather than sooner, after Vandersteen had updated the Model Seven to Mk.II status.
