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.

"We don't have a price yet, because the TAD Compact Reference One Monitor loudspeaker is a prototype," stated Andrew Jones, lead engineer for loudspeakers at TAD Laboratories, Inc., shown here in John Atkinson's photo. "I can say that it will be somewhere between zero dollars and $60,000, the cost of a pair of our full-sized TAD Reference One speakers."

"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.

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.

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.

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."

Thiel's press conference at the Sands Convention Center on Day One of the 2008 CES opened with a detailed critique of the complexities and challenge of installing a home theater system. Ekin Binal, Vice President, Product Development, of BICOM, an IT company partnering with THIEL to address these issues, spoke in detail about the complex, labor intensive, time-intensive, cost-intensive installation of multiple speakers and channels. Furthermore, updating such a home theater system is never simple nor convenient, nor is moving a system from an old house to a new house either simple or inexpensive. Because installation is custom work, there is no universal package a single manufacturer can create that can fit most domestic locations.
