Yes, those are moving-coil woofers. From Martin-Logan, the electrostatic company. ML’s new Motion Series speaker, to be priced at around $3000/pair when it is available in the late summer, is a big brother to the Motion 40 tower. The speaker uses the largest yet Folded Motion XT tweeter to come from MartinLogan, marrying it to a 6.5" midrange unit and a pair of 8" woofers. and although the company is still based in Kansas, its speakers are now made in Canada. Though it was demmed with Peachtree amplification, the speaker suffered from the suboptimal room acoustics.
Arcam used to CES to launch a “statement” integrated amplifier, the FMJ A49. Priced at $5000, the A49 offers 200Wpc into 8 ohms (with the first 50W in class-A), 400Wpc into 4 and features a class-G output stage, fully balanced topology, MM/MC phono stages, and a onboard power supply for Arcam’s rSeries of wired and wireless DACs. While Arcam’s lower-priced products are made in China, the new amplifier is the first products to be manufactured in the USA, at the parent company’s facility in Rochester, New York.
The German ADAM company has been developing the idea of the Air Motion Transformer HF unit, originally developed by Dr. Oskar Heil. The latest version of their tweeter, the X-ART tweeter, is featured in the Mk.II version of the Tensor Beta loudspeaker ($25,000/pair), which was being demmed with Cary electronics. The X-ART tweeter is married to a folded-ribbon upper-midrange unit, a new lower midrange unit and two woofers, all mounted on a solid aluminum baffle. The enclosure is made from 1” and 2” MDF panels, extensively crossbraced. Interestingly, waffle-shaped inner panels are loosely filled with steel shot, which absorbs vibrational energy. The speaker is also supported on fluid-filled feet to further absorb vibration.
Scottish manufacturer Tannoy was showing the Carbon Black version of the Kingdom Royal speaker ($85,000/pair), which adds carbon-fiber trim panels, individually machined metal components, and a “specially formulated” paint on the cabinet surfaces. The speaker combines a 12” Dual-Concentric driver with a supertweeter and a 15”, vented woofer with a corrugated surround for maximum linearity. The Kingdom Royal looked elegant indeed, and driven by Cary single-ended power amplifiers with Cary’s new streamer as source, the full-range, wide-dynamic-range sound was equally elegant.
On first glimpse, Nola’s Carl Marchisotto appeared to be demming the same Concert Grand Reference Gold loudspeakers he had shown at the 2013 CES. However, those were the preproduction protypes and the 2014 show featured the production version. Costing the same $197,000/pair, the speaker features a new ribbon supertweeter taking the response up to 100kHz and two new Gold Technology woofers operating below 40Hz. Driven by an Audio Research Reference 75 stereo amplifier and an Audio Research Reference 10 preamp, with source two United Home Audio Tape decks running 15ips, 2-track analog tape and hooked up with Nordost Odin cabling, the sound in this room had an impressive, full-range sweep that usefully loosened up as the show progressed and the speakers/system broke in.
With new US distribution, by the Katli Audio Co. from LA, the Taiwanese Usher loudspeaker manufacturer premiered its Grand Tower flagship ($37,800/pair) at CES. Combining Usher’s diamond-dome tweeter with two in-house 7" midrange units and two Eton 11" woofers, the Grand Tower weighs 500 lbs and has a claimed low-frequency extension of 24Hz, with a 90dB sensitivity. My experience of a percussion recording suggests that both specifications are valid!
The Belgian Venture company introduced its Vidi speaker at CES. Costing $30,000/pair, the floorstanding, three-way Vidi speaker combines two 4" midrange units with a 1" tweeter and two 7" woofers, these mounted on the speaker’s sidewalls. All the drive-units use AGC (Abaca Graphite Composite) diaphragms. The crossover operates with first-order slopes at 250Hz and 3kHz and the speaker is specified as having a frequency range of 30Hz to 40kHz. Used fullrange but with an AW500 subwoofer also operating below 70Hz, the beautifully gloss-finished Vidis did a creditable job with the the live Bootleg Series recording of Bob Dylan’s "Desolation Row," played back from a laptop running the XX HighEnd software feeding digital data to a Weiss Medusa DAC. The opening up of the soundstage as the initially mono recording, made with a Nagra tape recorder, was spliced to the stereo backup tape when the Nagra ran out of tape, was delicious.
Jason Serinus mentioned the Rosso Fiorentino Florentia loudspeakers ($99,995/pair) in his report on the Graaf amplifier in the Avatar Acoustics room below. This four-way speaker enclosure features aluminum front panels and glass side panels and weighs 361.5 lbs. The midrange and treble units are mounted in an open baffle, while the top-mounted woofer and the twin 12" subs are mounted in sealed enclosure. The subs are driven by a 1500W amplifier and the sensitivity is claimed to be 89dB.
The Polar Vortex weather and its associated flight cancellations prevented Convergent Audio Technology’s Ken Stevens from reaching Las Vegas until the third day of the show. However, once he arrived, he set up a system featuring Vandersteen 5A Carbon speakers, connected by Stealth cables to his new JL5 Triode "Baby CAT" stereo power amplifier. This 100Wpc (8 ohms) amplifier costs $12,000 with amorphous core transformers and Black Gate capacitors, $10,000 with silicon-steel transformers. The circuit features what Ken calls "OptiBias"Ken describes this as "somewhere between constant current and constant power"which keeps the bias current of the output-stage KT120 tubes independent of fluctuations in the AC supply voltage. Those who feel tube amplifiers can’t rock hard in the bass should have experienced the Led Zeppelin track I auditioned in Ken’s room.
Shown in Tom Norton’s photo are the Platinum versions of Dynaudio’s Confidence C2 floorstander ($15,000, left) and C1 stand-mount (middle)loudspeakers in the new Platinum trim, which I had seen and heard at 2013 shows. But I was more interested in the news that the Excite 12 loudspeaker, which has been a reference for Bob Reina since he reviewed it in March 2010, has been replaced by the Excite X14 ($1500/pair). My photo wasn’t usable, unfortunately, but I auditioned the X14s in a system comprising the Octave V40 SE 45Wpc, tube integrated amplifier ($5300), T+A DAC S8 ($3250), with Amarra running on a MacBook, Dynaudio Stand 3X stands ($350/pair), and in-akustik Reference interconnects and speaker cables, and was impressed by what I heard.
