I guess Precision Transducer Engineering (PTE) didn’t get the memo—or maybe they wrote their own. (Their White Paper “The Case for Active Speakers” can be found here). The PTE Phoenix, a two-way, three-driver, largish stand-mounted speaker has three built-in 130W amps. The…

Active speakers—ie, those that that have built-in amplifiers—are generally unpopular with audiophiles. One well-known speaker designer working on his state-of-the-art speaker contender told me at CES that he would like it to be active but marketing told him that it wouldn’t sell, so he’s staying with the passive design.
The Phoenix, a large, attractive-looking three-way design with ceramic-diaphragm drivers, can be had in passive form for $75,000/pair or in active form for $95,000/pair. The active form includes a 500W class-D amplifier for the woofers and incorporates the Rives PARC low-frequency equalization. Demmed with VAC amplification driving the HF and MF sections, the active Phoenixes worked well on Charles Mingus Mingus, Mingus, Mingus, Mingus album, the low end sounding more evenly balanced than in most other rooms.
Listening to the big MartinLogan CLX full-range electrostatics ($25,495/pair) at the June 2012 Newport Beach Show had been a high point for me, though they were being demmed in too large a room. At CES, the CLXes were in a smaller room, and were being supported by a pair of MartinLogan's Balanced Force 210 subwoofers. Amplification was by Cello and the source included Berkeley's Alpha DAC. I sat down to listen to a 176.4kHz file of Respighi orchestral music from Referenece Recordings, but sadly it was not possible to form much of an impression, due to the conversations competing with the…
I had auditioned the Estelon X-Diamond speakers ($65,000/pair) at the 2012 Newport Beach Show, but the room there was not allowing the speakers to sound at their best. Driven by top-of-the-line, class-A Vitus amplification, these speakers, which use the 1.2" Accuton inverted diamond-dome tweeter, along with a 7" Accuton ceramic-cone midrange unit and an 11" Accuton ceramic-cone woofer, sounded much better at CES, even though the dem room was one of the infamous split-level rooms at the Venetian.

Erick Lichte was very impressed with the Marten Django XL loudspeaker when he reviewed it last September. The three-way Django costs $15,000/pair, but CES saw the debut of the two-way Django L, at a more affordable $9000/pair. A 1" Accuton tweeter is married to two 8" woofers and the sound on Peter Gabriel's "Don't Give Up" was much better-integrated than I would have expected.
The rest of the system was all EAR: 890 power amplifier ($8295), 912 preamp ($13,000), DACute ($6595), and a Discmaster turntable ($28,000) fitted with two Helius Omega tonearms and a Dynavector XV-1S cartridge.…
Invented by Oskar Heil and made popular by speakers under the ESS name in the ‘70s, the Air Motion Transformer (AMT) tweeter and midrange have lost popularity for a while, but have made a major comeback in speakers made by a number of manufacturers, including ADAM Audio in Germany. The Column Mk.3 ($7000pair), reviewed by Kal Rubinson in August 2012 was used by Cary Audio at CES, and had what I now think is a sonic signature that’s apparent in a variety of loudspeaker designs: low in coloration and detailed without being overly bright.
Using the same treble and upper-midrange Air-Motion Transformer units as the Class Column 3 that Bob Deutsch writes about in the next story, the much more expensive Tensor Beta Mk.2 ($35,000/pair) adds new lower midrange unit and woofers, all with Hexacone diaphragms. The massive, cross-braced MDF enclosure features a 22mm-thick aluminum baffle and the interior walls are faced with a unique plastic-honeycomb substance with the cells filled with steel shot. The shot very effectively absorbs vibrations.
Driven by Accuphase amplification and hooked up with Clarus cables, the sound in this…
Although a number of speaker manufacturers use Heil AMT drivers, only one company has the rights to use the name of the original speaker company that used Heil drivers: ESS. Headquartered in South El Monte, CA, ESS Laboratories LLC (which we might call “ESS Reborn”) also owns the rights to the original slogan, “Sound As Clear As Light.” Unlike the speakers by ADAM Audio, GoldenEar, etc., these speakers look just like the original ones from ESS. President and CEO of ESS, Ricky “Rico” Caudillo, seen in the photo, told me that he wanted to stay with the original, highly-successful designs, but…
T+A (Theory and Application) is a German audio company best known in North America for their electronics and source components, not their speakers. That’s about to change with the appointment of Dynaudio as T+A’s North American distributor, and the introduction of the T+A Criterion line of loudspeakers. Asked whether Dynaudio—which, of course, is a loudspeaker manufacturer—has collaborated with T+A on the design and/or manufacturing of their speakers, Dynaudio’s Mike Manousselis quickly assured me that Dynaudio functions only as the distributor for T+A; the T+A speakers are manufactured…
Distributed in the US by Colleen Cardas Imports, the new Moos Mini Aero speakers ($2499/pair) represent a serious attempt to get good sound from powered wireless speakers. Founder of the Australian company, Tom Celinski, shown in the photo and once with Linn, told me that the two drive-units are ScanSpeak Revelators and, in fact, the speakers are assembled by ScanSpeak. A USB2.0 interface guarantees bit-accurate transmission of digital audio at up to 24bit/96kHz. The wireless data are fed to a DSP-based digital crossover running on Analog Devices SHARC floating-point chips. Thee crossover in…
