The main inherent advantage of the full-range electrostatic loud speaker system is that it allows a single diaphragm to embody the conflicting attributes needed for optimal performance at both extremes of the audio range. Its thin-membrane diaphragm can be made exceedingly light, for superb transient response and extended HF response, yet it can be about as large in area as desired, for extended LF response.

It's a tense moment during a suspense thriller. A cannibalistic serial killer has escaped from a maximum-security detention unit and eluded capture for long enough to work up a healthy appetite. Two small children are playing hide-and-seek in an overgrown lot behind their home.

Editor's Note: 24 years ago, in January 1995, we published the first issue of Stereophile Guide to Home Theater, a sister publication intended to appeal to the the growing number of home-theater enthusiasts. Stereophile's founder, the late J. Gordon Holt, had gotten early into the idea of accompanying movies with high-quality sound, and when I first visited his New Mexico home in January 1986, his system included an Advent NTSC-format video projector.

In the 1990s, while putting together one of my early hi-fi systems, I'd often visit New York City audio retailer Sound by Singer to gawk at their top-tier wares. On one such visit I noticed a serious-looking gentleman listening to Stravinsky's The Rite of Spring through a pair of Audio Physic's Step loudspeakers (accompanying electronics long forgotten). Sitting on their dedicated, minimalist-looking metal stands, the pint-size Steps were angled up 22° or so, to create a physical time alignment of the tweeter's and midrange-woofer's wavefronts. The Step looked odd—kind of scrawny. But these petite minimonitors projected music that seemed to exist entirely free of their cabinets, pulling off a sort of "disappearing" act I'd never before heard.
