ESB 7/06 distributed by Marrt Electronics, Cedarhurst NY 1981-84
My father was the US distributor of ESB ("ElectroStatica" - something). It was run out of high-end AV dealership Marrt Electronics in Cedarhurst, NY from about 1981-84, and exhibited at CES Las Vegas most of those years - which is where TAS's Harry Pearson likened the 7/06's to the best sound reproduction he'd heard other than the $30,000 Infinity RS system. (Thence the '$27,000 Off' ad campaign launched in Stereophile & Absolute Sound). At peak, they were in about a dozen high end dealers nationwide.
The 7/06 was the most popular model at a $3,000pr price point, although they also made a 2-foot-taller 7/05, as well as mid-range 7/07s $ 7/09s, in addition to smaller "box speakers" comparable to Yamaha's top offerings. Handmade and finished of piano-grade hardwoods, they feature fusible links and individual drivers that can also be replaced.
You can still find Doug Sax's review online. My father's illness & death ceased US distribution in 1985 - don't know what became of the Italian manufacturer, though they had been the largest Neapolitan speaker maker at the time.
