Two brothers-in-law in a town on the Limfjord.

Jamo’s name is its origin story. The company was founded in 1968 in Glyngøre, a small fishing town on the Salling peninsula in the Limfjord, by Preben Jacobsen and his brother-in-law Julius Mortensen, and the name joins the first letters of their surnames: Jacobsen and Mortensen. Danish Wikipedia and the company’s own history agree on the year and the founders. The Danish broadcaster DR, in a feature on Denmark’s loudspeaker history by Søren Bjørn-Hansen, describes Jacobsen as a carpenter; the company calls him a cabinetmaker with a knowledge of acoustics, and Mortensen a salesman from the fishing industry.

The company says it began in a hen house and that within two years the founders had built their own development and production building. It says its one millionth loudspeaker was made in 1978, ten years after the start.

Jamo grew into the largest loudspeaker maker in Europe. Danish Wikipedia gives 1994 as the year it held that position, and the company says the same, adding that its factory then covered 28,000 square metres. Sources differ on its peak workforce in Glyngøre: DR and Danish Wikipedia say about 600 people, while English Wikipedia and other accounts say more than 400. By 1998, Danish Wikipedia says, it had made and sold more than 11.5 million units; DR puts the figure at more than 10 million in the first 30 years.

The company also lists milestones we have not checked independently: that in 1991 it was the first audio maker to receive ISO 9001 certification, that in 1994 it made the first THX-certified loudspeaker from Europe, the Middle East and Africa, and that it was listed on the Copenhagen Stock Exchange in 1996. We give those as the company’s claims.

From the Limfjord to Indianapolis.

The decline came quickly. DR says the founders sold Jamo to a Norwegian investment fund; Danish Wikipedia names it as FSN Capital. In 2002 the businessman Anders Høiris was hired as chief executive to reverse falling sales, Jyllands-Posten reported. When that did not work and FSN Capital withdrew, ownership passed to Jyske Bank, Danish Wikipedia says, citing Business.dk. Production has been in China since 2004, according to Danish Wikipedia; DR dates the closing of the Glyngøre factory to 2006, so the sources do not agree on when manufacturing in the town ended.

In 2005 Jamo was bought by the American loudspeaker maker Klipsch, a deal Høiris had arranged before leaving, Danish Wikipedia says. Development moved to Viborg — in 2006 according to Danish Wikipedia, in 2008 according to the trade paper Electronic Supply — and in 2009 Klipsch closed the Viborg office to bring its loudspeaker brands together in Indianapolis. In February 2011 Electronic Supply reported that Jamo’s two remaining Danish developers, Michael Sørensen and Michael Ankersen, were moving back into the old Glyngøre buildings. That year Klipsch itself was bought by Audiovox, which renamed itself VOXX International, and the regional broadcaster TV Midtvest, citing Morsø Folkeblad, reported that development would move again, partly to Paris and partly to the United States. The old factory became a business centre known as the Jamo-Huset.

The brand kept selling under Klipsch. In October 2022 Essential Install reported the Studio7 series of six speakers, priced from £299 to £949, with cabinets tilted back by seven degrees and a design described as inspired by Nordic landscapes.

A Danish loudspeaker country.

Denmark has been making loudspeakers and audio equipment for a century. Bang & Olufsen was founded in Struer in 1925 by Peter Bang and Svend Olufsen, and Ortofon began in Copenhagen in 1918 as the Electrical Phono Film Company, according to English Wikipedia.

Much of the industry grew around drive units. The loudspeaker factory that became Vifa was set up in Videbæk in 1933, initially supplying Bang & Olufsen, English Wikipedia says; Vifa took over the driver maker Scan-Speak in the late 1980s and its Danish rival Peerless in 2000, and in 2005 the combined business passed to Tymphany, which sold Scan-Speak to its Danish management in 2009.

Complete-speaker brands followed: Jamo in 1968, by its own account; Dynaudio in Skanderborg in 1977; and DALI, founded by Peter Lyngdorf in 1983 and based in Nørager, according to English Wikipedia. Several have since passed to foreign owners — Dynaudio to China’s Goertek in 2014, and Jamo to Klipsch in 2005.

The makers in this guide are spread mostly across Jutland, with one on Zealand: Jamo, founded at Glyngøre on the Limfjord; Scan-Speak in Herning; Raidho at Pandrup, care of Dantax; Børresen in Aalborg; Audiovector at Skovlunde, outside Copenhagen; Densen, founded in Esbjerg and moved to North Jutland after a 2021 change of ownership; and Lyngdorf in Skive — according to their own websites and Danish trade press.

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 name sold, and sold again.

In 2024 VOXX let the brand go. On 5 September 2024 it announced the sale of its “premium audio brands Jamo™ and Energy™ to Rayleigh Lab and Cinemaster, including inventory, for approximately $3.2 million,” as part of a restructuring; its filing with the US Securities and Exchange Commission gives the closing date as 31 August 2024.

The new owner is Jamo Holding Limited, which the company’s website says was established in 2024. In April 2026 audioXpress reported that it had been set up to restore the brand, with Cinemaster, a distributor, and Rayleigh Lab, a research and manufacturing company in Shenzhen, China, as partners. It named Xiaodong Yang, Cinemaster’s founder, as chief executive and Rayleigh Lab’s founder Thomas Li as head of manufacturing, and said production would be split between Denmark and China, with design work by Kim Michel, by Simon Matthews and Jamie Cobb of Studio ISO, and by the Danish agency HarritSorensen. The new range was to be shown at the High End show in Vienna in 2026. “Jamo is a legendary brand for good reason — great sound and clever design never get old,” Yang told the magazine.

The company’s website now speaks of “Scandinavian restraint, craftsmanship, and devotion to detail,” and presents Denmark as the brand’s home. We could not confirm which products, if any, are now made in Denmark; we report the split as the owners describe it. Older claims about Jamo, such as the 2008 award for its R909 loudspeaker that the company lists, rest on its own account.

For a design guide, Jamo shows how a name built from two founders’ surnames can outlast the factory, the founders and several owners. Compare DALI, another Danish loudspeaker maker that grew into an export business, and Dynaudio, which has also passed into foreign ownership. For this guide we use a deep fjord blue, linen and oak with a sans, an unofficial interpretation; no product or logo is reproduced.
