One of the coolest parts of the drive from Southern California to Las Vegas is the Cajon Pass, especially if you're a rail fan like me. The Cajon Pass connects the So Cal basin with the High Desert where multiple rail lines weave through spectacular geography rising from sea level to over 4000 feet elevation. These mile-long container trains carry goods shipped from Asian ports to the Ports of Los Angeles or Long Beach and then to destinations in the Midwest or East Coast. Perhaps your next flat-screen television, home theater system or disc player is in one the containers on this train.

A power amplifier is the last electronic component in the audio chain—well, next-to-last if you count the speakers—and it has several important tasks. It must amplify a very small audio signal without changing the signal's characteristics, it must precisely control each speaker in the system, and it must instantaneously deliver adequate voltage and current to each speaker on demand. As such, the power amp is where the rubber meets the road.

On the Edge of a cool idea, that is. Paradigm Electronics of Canada provided a sneak preview of its new Edge, a fully integrated 2.1-channel compact entertainment system. Product details are not finalized, but the model shown has an iPod dock, a DVD player, a built-in down-firing subwoofer, composite video inputs, S-video and component video inputs and a video scaler that improves resolution to 1080i. The demonstration room was very noisy but the bass sounded very compelling. The Edge is expected to sell for $499 and will be available in the spring of this year.

As in-wall speakers have grown in popularity, manufacturers have introduced in-wall subwoofers to complete the package. They have also struggled to deal with the inevitable rattles and vibrations of a subwoofer mounted inside a wall. Paradigm has introduced the RVC-12SQ Architectural Subwoofer, which solves the vibration problem by using two drivers in-phase but firing in opposite directions, thus canceling vibrations. The drivers face each other and fire horizontally rather than from front to back, further reducing vibrations. The RVC-12SQ can be used as a standalone sub or with the optional enclosure shown in the photo. The new Paradigm sub will be available in the first quarter with price to be announced.

I love big, beefy power amplifiers for the same reason I enjoy high-performance automobiles. An economy car will get me to my destination, but it's just not as much fun.

Phase Technology has introduced two sound bars, the Teatro V-3.0 and Teatro PC-3.0 from their Velocity and Premier Collection. The sound bar shown in the photo is the Teatre PC-3.0. A unique feature of the Phase Tech sound bars is the midrange driver mounted on the sides of the enclosure (see photo) in order to produce a wider soundstage, which it does very effectively. During the first concert video demo I thought I was listening to the floorstanding speakers and not the sound bar. Another unique feature is the EVT (Enhanced Voice Technology) designed to increase dialog intelligibility.

Pioneer Electronics introduced its first in-wall speakers at CEDIA, 2008 in Denver, Colorado. Since that time they have expanded the line to include Elite branded models. I met with Andrew Jones, Pioneer's chief speaker designer and he explained that the new Elite in-walls are designed to optimize the sound quality of new lossless audio formats and to minimize the inevitable problems associated with installing a speaker in a typical residential wall. In general the performance of an in-wall speaker can be compromised due to the wall cavity in which it is installed, but with the right construction materials an in-wall speaker can provide excellent performance. Pioneer uses titanium tweeters, woven fabric speaker cones and cast aluminum frames to maximize the audio performance of its new models. Pioneer also developed Coherent Source Technology to improve off-axis performance with smoother overall frequency response. To fine tune the sound, the new in-walls include bass and treble controls. I look forward to reviewing the new models when they become available in spring, 2009. Prices were not available.

RBH Sound showed its new high performance Signature Series speakers, dubbed the 8300-SE and the reference version, the 8300-SE/R. The 8300-SE features three 8-inch aluminum cone subwoofers, two 6.5-inch mid-bass drivers and 1-inch soft dome tweeter. The 8300-SE/R, shown in the photo has upgraded 6.5-inch mid-bass drivers with a phase plug, a liquid-cooled Scanspeak silk dome tweeter and a modified crossover network resulting in increased power handling capacity. The 8300 speakers can be bi-amped or bi-wired.

Not long ago, large floorstanding speakers were preferred—practically required—to get the sonic performance demanded by audiophiles and home-theater fans. Smaller speakers simply couldn't adequately reproduce the wide dynamic range and clarity of today's high-resolution digital sources.
