We get a kick out of Paul Barton, so we wandered into PSB's room to see what's new. He was talking to a good-looking man of a certain age (ours, approximately), to whom he introduced us: it was Vance Dickason, the man who wrote the book on designing DIY loudspeakers: The Loudspeaker Design Cookbook.
Joe Harley was striding around the Denver Convention Center. When we shook hands, he glanced around and said, "Let's go somewhere private." We ducked into an empty demo room and he pulled a few records out of his bag. "Nobody else knows about this, I'm giving you the exclusive."
Look at the picture and tell me that those don’t look like speakers! They are, of course, but they are not intended to be driven by audio signals directly. What subwoofer manufacturer Bag End was demonstrating is a small, active bass trap, the E-Trap, and they are driven by the bass frequencies in the room. Each of these small boxes contains a driver, two microphones, and some pretty snazzy electronics that let the driver cancel the energy at the frequency (or two) of your room’s major mode. Sure, acoustic treatment is generally best, but that can get awfully cumbersome below 100Hz. Adjustments allow you to select frequencies between 20Hz and 65Hz and adjust the amplitude and shape of the cancellation. For critical success, you need to experiment with placement (although that is almost always at a room boundary) and, at the moment, have access to some nice FFT software. Bag End's James Wischmeyer promises that, eventually, some simpler setup software will be provided. Mebbe, but I asked to try one ASAP.
Thiel was showing honest-to-God production samples of its CS3.7 ($9900/pair), which has a few cosmetic flourishes I hadn't noticed the times I spotted prototypes at earlier Shows. I could be wrong, but that aluminum cowling looks better-integrated with the body than I recall.
What Mirage did display for real was the OM-28, their $7500/pair floorstander that boasts a real-size omnipolar titanium-dome tweeter, a 5.25" carbon-fiber midrange driver, and two 8" carbon-fiber woofers. The cabinet is ported with down-firing vents.
Dynaudio actually had a "production prototype" of its $16,500 Sapphire 30 30th anniversary loudspeaker at CEDIA, seen here photographed by Kal Rubinson. All of the drivers are "Evidence-grade," Michael Manoussellis told us. The drivers are Dynaudio's 1.1" (28mm) soft-dome tweeter, 5.5" (15cm) MSP-cone midrange, and two 8" MSP-cone woofers. The cabinet is faceted, hence the jewel reference. It's pretty dramatic looking. Now we're slavering to hear it.
McIntosh has introduced a turntable. It has the classic black and blue faceplate, which looked a tad bizarre to these eyes. The platter is "polished, fully-balanced green tint," meaning glass, we presume. The tonearm and cartridge are custom-made by McIntosh. An isolated speed stabilizer drives the precision motor.
Lyngdorf was showing a $16,800 system that incorporated its RoomPerfect digital room correction system, which creates an EQ curve based on measurements taken in seven positions. The result is said to be a sweet spot that is spot-on in one position and "extremely fine" for up to eight target positions.
