The BeoLab 3, shown here with acoustic engineer Peter Chapman, is a tiny sphere with a small woofer-midrange, a single Acoustic Lens tweeter, and a two on-board ICEpower amps, all in a tiny, spherical cabinet with an internal volume of 1.5 liters. It sounded remarkably close in balance to the big BeoLab 5 (the deepest bass and ultimate volume capability excluded, of course).

Speakers for cordless phones, another B&O product category, must be tiny. Looks like it also might make an interesting tweeter, though probably not, as the frequency response of telephone drivers is band limited by design.

"The Cube" is the first stop in testing a B&O loudspeaker. At 12x12x13 meters it is the world's largest privately owned sound test room. It is not an anechoic chamber. Instead, B&O built a space large enough to use MLS measurements to a high degree of precision. MLS measures the speaker's response to an impulse. This result is then gated to eliminate the effect of the sound reflected off the walls. The reproduced and filtered impulse is then converted back to a frequency response (techies will recognize this as a Fourier transformation). The two walls of the chamber are damped, not to eliminate reflections but to speed up the time between impulses (a number of impulses are averaged for greater precision). The support structure shown here holds the loudspeaker (in the photo it's one of B&O's very tall, pencil-thin designs). The mike is visible in the distance. Measurements are made in 140 different directions.

It all starts with the mother glass. That's the foundation for building an LCD panel. Everything else—the individual red, green, and blue elements of each pixel and the interconnects necessary to drive them—are grown on it.

Toshiba showed its first outboard HD DVD-ROM computer drive.

Sharp was only one of a number of manufacturer's showing new Blu-ray recorder/players, most of them also including hard drives. Sharp's was particularly classy, with a wood-grained top. None of these recorders are destined for the U.S. market.
