Jim Thompson from Egg.Works, the firm that manufactures Eggleston loudspeakers, was eager to tell me more about the Eggleston Nine. I'd seen the firm's loudspeakers in many different CES suites over the years, but never had a chance to listen to them before.
Paul Barton, founder and chief designer of PSB Speakers International, plans to manufacture a new series of loudspeakers he is calling "Imagine." This line will feature new finishes and styling. The enclosures will be curved, both front to back and top to bottom. To create this shape, PSB is laminating multiple layers of MDF, w2hich is then braced to a mold. Radio frequency waves are directed at the enclosure shell for 15 seconds that quickly sets the glue. Once the enclosure is stable, holes are machined as the exact places required, which eliminates the tedious job of making ultra-precise adjustments when an enclosure is built around the drivers. PSB also uses a method of adding color after the first coat of clear sealant is applied to the veneer, so the resulting finish shows the wood grain but also has a rich, red color.
"The technology to create a full, wireless, 5.1 channel audio system simply wasn't available before, "said Mike Gough, B&W's Senior Project Manager on the Liberty System, "so we waited until it was possible to do it right." The Liberty employs a proprietary, robust wireless protocol with channel switching capabilities—called dynamic channel selection—to avoid interference from existing WiFi networks. Its wireless transmitter broadcasts 8 separate channels, allowing for full 5.1 in one room, and a stereo setup in a second room. Alternatively, the Liberty can support 4 separate stereo zones throughout the house.
Escalante Design's CEO and Founder, Matthew Waldron, and the company's design engineer, Tierry Budge, were on hand to introduce the $11,000/pair Pinyon, a lighter and less expensive version of their Fremont loudspeaker, which I review in the Febraury issue of Stereophile. Weighing 35 lbs each, the Pinyon includes two direct-coupled 6.5" woofers, and the same 1" ScanSpeak ring-radiator tweeter found in the Fremont. It comes with the Hoodooh Monitor stands that have a brushed aluminum inlay. Waldron had it playing with the 210 lb, 12", powered (500W), UINTA subwoofer, which is rated from 16–100Hz.
Jon Iverson, our magazine group's self-proclaimed “Web Monkey”—that’s how his business card describes his role—mentioned that a reader, now living in Dubai, wrote him Tuesday night about Gallo Loudspeakers. "I'm hoping your CES 2008 show blog will bring me up to speed on the latest loudspeaker from Anthony Gallo," he wrote.
Bryston's James Tanner surprised me by showing me a new direction for Canadian amplifier manufacturer Bryston: it has developed a series of class-D (switching) amplifiers. "You'll notice from the line's hybrid name that we combine the class-D output module with regular linear power supplies, not switching supplies," explained James. "The switching supplies are too noisy."
Daniel J. Hodgson, Polk Audio's Senior Vice President, was very enthusiastic about the $3000/pair LSi25, a floor-standing, 3-way loudspeaker."It has a 1" VIFA ring-radiator, dual-pivot tweeter to increase dispersion," said Daniel. There are two midranges that surround the tweeter in D'Appolito configuration, and a powered 10" sidefiring subwoofer. The drivers have cast speaker baskets with aerated-polypropylene cones. He went on to point out the two small ports on the front baffle next to the midrange. "These two small ports are designed to eliminate resonance, which our company calls Acoustic Resonance Control," added Michael Cooper, Florida Regional Sales Manager for Polk.
Erin Binal of Bicome finished his lecture on Thielnet by stripping off the front grillw on the small, two-way, IP-addressable, powered SCS4D loudspeaker. There are twin ports above and below the coaxial driver. With the grille on or off, the SCS4D is rated with a frequency response of 48Hz–20kHz, ±3dB. Pricing was not specified. And yes, those are WiFi antennae.
"Our Asian and Pacific clients were strongly requesting it," said Mark Levinson's Walter Schofield, VP of Sales and Marketing, "so we designed an amplifier in the older Mark Levinson tradition with external heats."
