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 isn't immediately obvious that the JVC LT-46FN97 ($3,499.95) stands out in a sea of new flat panel displays. Its styling is attractive but generic. Its feature set is good though hardly revolutionary. But when I first saw it in action at a JVC line show I knew I wanted to review it. Two other trade shows intervened before I had a chance to spend time with this 46" 1080p LCD set in my own studio, but demos at both shows made me even more anxious to check it out.

Given Pioneer's current prominence in the world of plasma displays, DVD players (plus soon, they trust, Blu-ray Disc), and other home audio and video electronics, it may surprise you to learn that it began as a speaker company. In fact, Pioneer speakers still have a significant market presence in many parts of the world.
