A session guitarist who took a singer’s advice.

Von Schweikert Audio is the loudspeaker company of the late Albert Von Schweikert (1945–2020), and its history is mostly his. According to an obituary by Greg Weaver published by The Absolute Sound and Positive Feedback in 2020, he spent much of his childhood in Heidelberg, Germany, where he studied violin and piano, moved to the United States in 1962 and paid his way through college as a session guitarist. Weaver and Stereophile both tell the story that turned him into a speaker designer: on tour with Sonny and Cher in 1967 and Neil Diamond in 1968, he rebuilt the bands’ public-address speakers with JBL drivers, and Diamond told him his speakers were better than his guitar playing. It is a family story, told by his son Damon to Stereophile, and we give it as such.

He then went to California. Weaver says he enrolled at Caltech around 1976 and worked under Richard C. Heyser, the inventor of time-delay spectrometry; Stereophile also says he studied under Heyser. The company’s website calls him “a Caltech educated physicist and professional musician”; we could not confirm a degree. There he developed what he called Acoustic Inverse Replication, the idea that a speaker should behave like “a microphone in reverse,” which Weaver says he published in 1980. It explains the rear-firing “ambience” drivers that still appear on Von Schweikert speakers.

Before he had a firm of his own he designed for others. Weaver and Stereophile both say he worked with Oskar Heil, inventor of the Air Motion Transformer tweeter, and then for the parts supplier KSC Industries, where he designed drivers or crossovers for brands including Klipsch, Polk, Infinity, Apogee and JBL. His first loudspeaker, the Vortex Screen, dates from 1978, according to Weaver, and was reviewed by Robert Harley in Stereophile in 1989.

Watertown, a flood and a fresh start.

The founding date depends on whom you ask. The company’s website says “since 1975” and celebrates “50 years,” counting from Albert’s early work. Weaver writes that he started Von Schweikert Research in 1994 to make the VR-4, a speaker selling for under $4,000 whose name stood for “Virtual Reality in 4 dimensions,” and Damon Von Schweikert gave Stereophile the same year in 2020. Michael Fremer, reviewing the Ultra 55 for Stereophile earlier that year, wrote that Albert founded his namesake company in 1996. We use 1994 and note the difference.

The first company did not survive. In the mid-1990s, Weaver says, it moved to Watertown, New York, between Syracuse and Ottawa, drawn by promises of state and local development support. In January 1999 unseasonably warm weather melted the snow, and runoff from a nearby hazardous-waste dump flooded the workshop and destroyed its stock, at a loss Weaver put at more than $300,000. Von Schweikert Research folded. Albert returned to Southern California and started again as Von Schweikert Audio — in San Diego in 2000, according to Damon’s account to Stereophile.

The new company kept his ideas: rear ambience drivers, the crossover thinking that Fremer singled out among Albert’s concepts, and a cabinet the website describes as a “triple-wall” laminate of high-density fibreboard, synthetic stone and damping material about three inches thick, which it dates to 1994. In 2015, Weaver says, Albert completed his swan song, a one-off, nine-foot, six-enclosure speaker called the VR-111XS, priced at $750,000.

Design and documentation.

Beside the names that defined American high-end audio sits a second tier of smaller companies, most started by one designer or one family. Where they differ most is ownership.

Some are still led by their founders. Bel Canto Design says John Stronczer founded it in Minneapolis in 1991 and that its products are built there. Zu Audio, founded by Sean Casey, says its products are made in Ogden, Utah. Dan D’Agostino co-founded Krell in 1980 with Rondi D’Agostino, English Wikipedia says, and left it in 2009; his own company says it was founded in 2011 and builds by hand at Cave Creek, Arizona.

Others are family businesses. VTL traces itself to David Manley’s amplifiers of the early 1980s; in 1993 father and son parted, Luke Manley kept VTL, and it says all its products are made in Chino, California. Von Schweikert dates itself to 1975; its founder, Albert Von Schweikert, died in 2020, and his son Damon is listed as co-founder and CEO, with cabinets made in California, the company says.

Two have changed hands. Parasound, founded in San Francisco in 1981 by Richard Schram, was sold to David Sheriff in December 2022, the company says; its website now gives Las Vegas as its location. GoldenEar, launched by Sandy Gross in 2010, was sold by The Quest Group to PML Sound International, joining Paradigm, Anthem and MartinLogan from January 2025, GoldenEar announced.

This guide sets out what can be checked about each brand — who founded it, who owns it, and what it says about where its products are made — and marks clearly what rests only on the company’s own word.

A family firm in Riverside.

The succession was set out in a September 2015 announcement carried by The Absolute Sound. Von Schweikert Audio had bought Endeavor Audio, a smaller speaker maker founded by Leif Swanson, who became vice president of sales and marketing, and Damon Von Schweikert had become chief executive, leaving his father to concentrate on engineering. Fremer and Weaver both say Swanson took over as chief designer that year and Albert retired. Albert Von Schweikert died on May 29, 2020, Stereophile reported. We found no record of the company being sold; Damon still leads it, and the website names Gary Leeds, whose firm Hear This imports audio electronics, among its leadership.

In 2020 Stereophile listed the company in Riverside, California, and the support telephone number on its website still matches that listing. The magazine’s specification sheet for the Ultra 55 that year read “Made in USA,” with prices of $95,000 to $100,000 a pair, Accuton ceramic drivers and a finish of “any automotive polyester color.” The current range runs from the VR.30 and VR.50 to the Ultra.5, Ultra.7, Ultra.9 and Ultra.11. The company says the VR.30 was named The Absolute Sound’s 2026 high-end loudspeaker of the year, which we have not checked; the same magazine’s “Golden Ear” award, which the company also cites, has nothing to do with the loudspeaker brand GoldenEar.

For a design guide, Von Schweikert Audio shows how a brand can rest on one designer’s theory and survive him. Compare Wilson Audio and Vandersteen, two other American loudspeaker makers built around a founding designer. For this guide we use lacquer black, a pale celeste blue and stone grey with a serif, an unofficial interpretation; no product or logo is reproduced.
