"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.

This is the R&D prototype for the BeoLab5, shown with the project's lead designer, Gert Munch.

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 BeoSound 4 is an all-purpose CD, radio, SD card slot, and optional Digital Audio Broadcasting (European format) music system. The pyramid-shaped BeoLab 4 speakers are self-powered, with digital amplification. Approximately 8" high, B&O calls the BeoLab 4 a multi-purpose unit, suitable for a small stereo system, for a music system or computer, or as a surround sound speaker in an AV setup. It can be placed on a desk stand, floor stand, wall mounted, or hung from the ceiling.

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).

B&O began as a radio manufacturer in the late 1920s, operating out of Svend Olufsen's family farmhouse outside of Struer, Denmark. Its first product, the Eliminator, was designed to allow a radio to be powered by line voltage instead of a battery. The photo shows B&O consultant Ronny Kaas Mortensen next to the radio. The small box at the upper right hand corner of the radio is the Eliminator. It was not only built inside the radio itself, but also sold separately. It also cleaned up the dirty power line output of the day—the first audiophile high-end power conditioner!

B&O has produced televisions since the early 1950s. This is its first.

The BeoVision 9 television, which just started shipping, is B&O's current flagship 50-inch plasma. The 50" set, at around $20,000, may seem pricey for a 1366x768 design (it uses Panasonic glass), and it is. But it does include a built-in center speaker with an Acoustic Lens tweeter and 5" woofer. It also features an on-board version of B&O's BeoMedia (available separately in the BeoSystem 3), which includes all of the features of a sophisticated pre-pro and more. These include full 7.1-channel decoding (expandable up to 10 channels), speaker switching and speaker assignment options that may be the most flexible on the market, and easy access to sources as diverse as CD, radio, cable TV, satellite TV, DVD, photos, digital cameras, and the Internet. And oh, yes, the entire cabinet has a motorized swivel. Very cool.

If stepping off the plane into the Copenhagen airport is a little like stepping into the world's biggest IKEA store, then stepping out of the tiny airport in Karup, Denmark is a little like transporting to the farmlands of Nebraska. But my mission to the far west end of the Jutland peninsula, together with a number of other European and North American journalists, was not sightseeing, but information. Information about what Struer, Denmark manufacturer B&O is currently about, and how the activities in its several facilities are leading to interesting new products, and how those products are influenced by the thinking and research behind them.

On a recent visit back to Los Angeles I took in the 2016 Newport, California hi-fi-show, more properly known as T.H.E. (The Home Entertainment) Show Newport (though it’s now actually held in Irvine). You can read my observations on the show, along with those from other Stereophile contributors (I write occasional reports and reviews for Stereophile, though Sound & Vision is my main beat) at Stereophile.com. Like virtually all such events (of which there are several in the U.S. each year under various management), this was a show for 2-channel audiophiles. Count me among them, but no more so than for multichannel music, movies, video, and home theater.

The only show in the U.S. that features video as it relates to home theater is September’s CEDIA Expo...

You know the gag. You see someone walking down the street and about to step on a banana peel. Do you shout "STOP," or remain silent and then applaud as he does an awesome pirouette.

Back in late July I blogged about a demo kiosk at my local Best Buy. You can scroll down and read about it. It was set up in a DirecTV promotion kiosk, but it wasn't clear whether or not it was also intended to promoting Best Buy's new video calibration services.

In my review of Samsung’s flagship UN75ES9000, 75-inch LCD-LED HDTV, I remark that potential buyers should beware of bad demos of this very expensive set ($9000). Such a demo could make it very difficult to justify the expense.
