The Genesis Advanced Technologies 7.2f claims to be the "new affordable reference for bringing true-to-life music into your home." And they have a formidable amount to technology in the speaker to support this claim. At the top, there is the latest version of the circular flat-ribbon tweeter that apparently has been steadily improved since it was first introduced in 1992 (and which, for once, owes nothing to Dr. Oskar Heil). A solid titanium-cone mid/woofer claims to deliver exceptional clarity and low distortion within its range (and the "oil-can" resonance is far outside the range where the driver is utilized), and a servo-controlled powered bass from an 8" side-firing aluminum-cone driver, is claimed to extend the response down to 22Hz. There is also a rear-firing tweeter, which can be turned off if desired. There is control over tweeter as well as woofer level. The price of all this technology is a very reasonable $9000/pair.

MartinLogan is famous for speakers that use electrostatic drivers—full-range or in combination with dynamic woofers—but they have more recently broadened their offerings to include non-electrostatic models. According to MartinLogan's Peter Soderberg, their aim is to produce speakers that approach the sound of their electrostatic models, but at a lower price and easier to drive. He says that this has become possible with their version of the Heil tweeter (the original Oskar Heil patent having expired). He did a comparison for me between their top-of-the-line electrostatic CLX ($25,000/pair), supplemented by the Depth 1 subwoofer ($2000), and the new Motion 40 ($1995), which uses the Folded Motion (aka Heil) tweeter, in both cases driven by Anthem's new class-D amplifier, top-of-the-line Conrad-Johnson preamp, with a laptop as source. With Patricia Barber singing "Norwegian Wood," the tonal balance of these physically very different speakers was surprisingly similar. Peter Soderberg is pictured here with the CLX and the Motion 40, after what must have been an exceptionally amusing quip on my part.

The GoldenEar Triton Two, which I reviewed in the February 2012, issue, is my favorite speaker at anywhere near its price ($2499/pair until February 1, when it goes up to a still-very-reasonable $2999/pair). The Triton Two now has a "little brother": the Triton Three ($1999/pair), is a smaller version of the Triton Two. The resemblance goes beyond the physical; listening to a pair of Triton Threes, I was very much reminded of the Twos: the same sort of expansive soundstage and bass that was very nearly as impressive as I'm familiar with from the Twos.

Atlantic Technology's AT-1, which uses their patented H-PAS venting technology, was one of the hits of last year's CES, and the positive impression was confirmed in Erick Lichte's review (September 2011). The H-PAS approach has now been applied to the new AT-2 ($1800/pair). The –3dB point is specified as 41Hz, which I'm told is an anechoic figure. This normally translates to in-room response to the low 30s, and the sound of the AT-2 in the Venetian's less-than-ideal space seemed to confirm this.
