The frequency response was measured in the listening window—spatially averaged to minimize room standing-wave problems—using a 13-octave warble-tone generator, which is said to be a little more analytical than the filtered pink-noise signal I have used in the past; in addition, the nearfield low-frequency response of each speaker was measured with a sinewave sweep to get an idea of the true bass extension relative to the level at 100Hz.

The most outstanding feature of the Rauna's spatially averaged room response (fig.1) was its flatness through the…

Henceforth, all Apple stereo downloads and streams would be at at least CD resolution; many tracks would be offered in higher resolutions, up to 24/192. Apple estimated that by the end of 2021, 75 million songs would be available at resolutions of 16/44.1 or better.

That's big news, but the Apple people on the…

On its website, in the Specifications section for its "R"-model loudspeakers (footnote 1), Audiovector offers a long checklist of technologies, many of them optional, some of them, called "Concepts," assigned snappy names and acronyms: IUC for Individual Upgrade Concept; LCC for Low Compression Concept; SEC for Soundstage Enhancement…

As with the Magico A5 loudspeaker that Jim Austin reviewed in the July issue, I drove my test gear to his apartment to perform the measurements of this large, heavy speaker. I used DRA Labs' MLSSA system, an Earthworks microphone preamplifier, and a calibrated DPA 4006 microphone to measure the Audiovector R 8's behavior in the farfield. (We maneuvered one of the speakers onto a dolly and aimed it across a room diagonal so that it was maximally distant from the sidewalls.) I used an Earthworks QTC-40 mike for the nearfield and spatially averaged in-room responses…

The Africans brought to the Americas to be sold into slavery were denied every vestige of their past except their memories. And yet, they preserved their rituals in dances, songs, and stories, playing the sacred rhythms that accompanied those rituals on whatever found objects they could use to fashion beats. The customs of American peoples from various African…
