Wei Chang, designer of the $3690 Sopranino electrostatic supertweeter that John Atkinson reviewed last May, was showing their bookshelf-sized, 42 lb monitor loudspeaker, the $14,690/pair Mythology 1, which incorporates the Sopranino for the top-octave driver.

The $80,000/pair MartinLogan electrostatic hybrid, the Neolith, played with wonderful spatial imaging and translucent sound. The speaker's enclosure was painted in a glossy, thick automotive glass red paint called Rosso Fuoco, but is available in 6 other colors.

As an audiophile, I've come to associate the size, weight, and price of a subwoofer as quick'n'dirty indicators of its quality. The subwoofers that have worked best in my large listening room—the Velodyne ULD-18 and DD-18+, Muse Model 18, REL Studio III, JL Audio Fathom f113, and Revel Sub30—each weigh more than 130 lbs and cost more than $2500. With some of my reference recordings, all of them have achieved what Robert Harley described in the April 1991 issue of Stereophile as the goals of a quality subwoofer: "seamless integration, quickness, no bloat, and unbelievable bass extension." Yet are back-busting weight, unmanageable size, and nosebleed cost essential to achieving those goals?

Subwoofer technology is moving fast, with automated room equalization and system integration now a reality. A wave of new products has appeared in the past five years, all using different approaches to solving the problems of optimizing subwoofer response in listening rooms.

I sought out Manley Labs, manufacturer of tube amplifiers and preamplifiers, at CES. The system in their room included a Music Hall mmf-2.2le turntable, the Chinook phono stage that impressed Michael Fremer last August ($2250), a Steelhead phono preamplifier ($8000), a pair of Snapper monoblock 100Wpc tube amplifiers ($7650/pair), which use four EL34 output tubes, driving Neat Acoustic Ultimatum XLS speakers. EveAnna Manley mentioned after the show that she was working on a secret, prototype1 DAC that promises "to beat all comers." I greatly enjoyed the audio I heard in the Manley Labs room at CES. I had to agree with the saying on the rug that appears at every Manley abs exhibit: "Tubes Rule!"

For the first time in many years, I walked into a room at CES and was immediately blown away. Pass Labs personnel had suggested I listen to the amplifiers driving Sony loudspeakers, so I went to the 30th floor of the Venetian to listen. I had no expectations, other than knowing that five Sony SS-AR1 loudspeakers ($27,000/pair) were powered by five Pass Labs Xs300 amplifiers ($85,000/pair), all connected by Kimber Kable. What I didn’t know was that Sony had given the two people running that demonstration, Blue Coast Records’ Cookie Marenco and Super Audio Center’s Gus Skinas, carte blanche permission to play any one of the 150 Direct Streaming Digital (DSD) master titles from Sony’s library for the duration of the Show.

At this year's CES, Sumiko's John-Paul Lizars introduced me to REL Acoustics’ new R528 SE sub-bass system. He described it as an "ultra-high output version of the R528" but also as a more compact version of the company's flagship Gibraltar 1 subwoofer. The R528 SE is half the weight (58 lbs instead of 108 lbs), 43% of the volume, and 61% of the cost of the G1 ($2750 instead of $4499). While the larger G1 has a 600W class-AB amplifier, the R528 SE has a 500W class-D amplifier. Both subwoofers utilize REL's aluminum-chassis, 12", carbon-fiber–cone woofer, but the R528 SE adds a downward-firing 12" passive radiator. Low-frequency response are not that different, with the R528 SE's –6dB point at 21Hz, and the Gibraltar 1's 15Hz. Many audiophiles and home-theater fans may end up favoring the more compact new subwoofer.

Enigmacoustics' Sopranino add-on electrostatic super-tweeter ($3900/pair) was innovative enough to garner a 2013 CES Design and Engineering Showcase Honors award. Mounted on a gray and white glass stand, the anodized aluminum cabinet and almost square speaker panel is small, measuring 7.2" x 7.7" x 8.3", and weighs 10.4 lbs each.

EgglestonWorks, who manufacture loudspeakers in Memphis, Tennesee, introduced a all-new version of their 150 lb, Nine Signature loudspeaker ($18,900/pair). This is a three-way speaker that uses a 1” dome tweeter, a sealed midrange section that incorporates two all-new carbon-fiber 6" midrange drivers, and a new dual-ported 8" bass driver, and is spec'd from 25Hz–20kHz, –3dB. This floorstander was powered by a new Rogue Audio Sphinx hybrid class-D integrated stereo amplifier ($1295), which played digital music files sourced through a dCS Puccini DAC and CD player.
