An interior designer’s garage prototypes.

Triangle was founded in 1980 by Renaud de Vergnette. The company’s own history page — which spells his name “de Vergnettes” — says he was 22, lived in Paris and worked in interior design and decoration before giving up the job to build loudspeakers, starting with prototypes in a garage. One dealer’s history gives the founding year as 1981, but the same page dates the first model to November 1980, as the company does.

That first model was the 1180. The company says it had two modules — a bass cabinet decoupled from a pyramid-shaped section for the midrange and treble — and used paper-cone drivers bought from the French maker Audax, with crossovers de Vergnette designed himself. Before the launch, it says, he took the speaker to La Revue du Son, then the leading French hi-fi magazine. Hifi Pig reported in 2015 that the CX2 of 1981 was the first Triangle with its tweeter mounted on top of the cabinet — a dealer dates it to 1982 — and that by 1985 Triangle was making its own drivers.

The company grew up in the Aisne, north-east of Paris. Its history says that after a few years in the family farmhouse it moved, in the 1990s, to a building on boulevard Jules Ferry in Soissons, and in 2004 into a purpose-built factory. That factory stands in Villeneuve-Saint-Germain, the commune adjoining Soissons, which is why sources give either name; the company’s legal notice lists its registered office there. In the 1990s, the company says, it also made a line of amplifiers, and its two-way “Minimum” bookshelf speaker “marked a whole generation of audiophiles.”

Horn tweeters and paper cones.

Triangle’s sound has been defined by its drivers. The company says de Vergnette chose paper cones from the start for their natural timbre. Hifi Pig reported in 2015 that its horn-loaded tweeters, developed in-house with injected-aluminium horns, had become a trademark, and that Triangle also sold drivers to other loudspeaker makers. A 2012 article by the retailer Fnac noted efficiencies typically between 90 and 93 dB, which makes the speakers easy to drive with low-powered amplifiers.

The ranges have kept their names for decades. Hifi Pig dated the Altair, with a curved cabinet, to 1990 and the first Esprit range, with the Antal TZX, to 1994; Fnac also listed Zenith, Celius, Lyrr and Genèse. The flagship Magellan range arrived in the early 2000s — 2002 according to French Wikipedia, 2003 according to Hifi Pig. Its Grand Concert was a 2.15-metre speaker with eight drivers, including bipolar midranges facing front and back, in a cabinet built in three parts, Fnac reported. An Anniversary range marked 30 years in 2010, followed by the Color range in 2011, Signature in 2013 and Esprit EZ in 2014, according to Hifi Pig; the company now sells 40th-anniversary versions of Magellan, Esprit and Comète.

A 2017 visit by the retailer Son-Vidéo described the work. In the driver workshop, “almost the entire process is done by hand” (our translation): a 16 cm bass driver for the Magellan Quatuor and Cello, with two glass-fibre cones and a cellulose honeycomb between them, was built at about twenty a day and tested with Klippel and CLIO measurement systems and in an anechoic chamber. Diapason d’Or awards hung on the walls, the retailer noted. The company says some of its staff have been there more than 35 years; its newer products include active and Wi-Fi speakers such as the Borea and AIO ranges.

French hi-fi and the record.

France has a long record in audio. Elipson, founded in 1938, is described by French Wikipedia as the country’s oldest high-end loudspeaker brand, and Cabasse, founded by Georges Cabasse in 1950, moved to Brest around 1960, the company says. Later came Focal, founded by Jacques Mahul in 1979 in the Saint-Étienne area which Belgium’s Barco agreed to buy, with Britain’s Naim, in 2026; the valve-amplifier maker Jadis, founded in 1983 and based near Carcassonne; Davis Acoustics, founded in 1986 and now in Troyes; and Devialet, founded in Paris in 2007.

Reviewing an Advance Paris CD player in 2025, Stereophile wrote: “Think French hi-fi and you think Focal, Triangle, Cabasse, Jadis, Devialet.” At home the trade gathers at the Paris Audio Video Show, held in October 2025 at the Palais des Congrès, and in magazines such as ON Mag.

The makers in this guide are spread across the country, according to their websites and the French company register: Cabasse at Plouzané, outside Brest; Triangle at Villeneuve-Saint-Germain, beside Soissons, in the Aisne; Elipson’s owner, AV Industry, at Champigny-sur-Marne, in the Val-de-Marne; Micromega, owned since 2021 by La Boite Concept, which assembles at Soorts-Hossegor, in the Landes; Atoll at Brécey, in Normandy; and Advance Paris in central Paris, with a design office at Brie-Comte-Robert.

YBA, named after its founder, Yves-Bernard André, is harder to place: China’s Shanling took a significant stake in it in 2009, What Hi-Fi? reported, and ON Mag wrote in 2025 that its products are designed in France but made under Shanling’s oversight.

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 friend of the founder, then his son.

De Vergnette did not stay. Hifi Pig reported in 2015 that the Decelle family bought Triangle in 2006 and reorganised it; the company’s history says its founder retired that year. La Gazette Picardie reported in 2022 that Olivier Decelle was a friend of the founder, and that his son Hugo Decelle, who had joined to help his father, now ran the company as its third head. The family also owns wine estates — five vineyards, including Château Jean Faure in Saint-Émilion, according to Hifi Pig — and in 2013 Triangle opened sales and marketing offices in a former wine-shipping building in Bordeaux, while production stayed by Soissons. The company today, Triangle Hi-Fi, names Hugo Decelle as its manager.

The Decelles took over at a hard moment. La Gazette Picardie reported that Triangle had employed up to 40 people, with €8 million in revenue, in the early 2000s. “Offshoring, but above all the rise of competing products such as Bluetooth speakers, meant our market was badly shaken up between 2006 and 2015,” Hugo Decelle told the paper (our translation). Staff fell to 15, and a large part of production was moved to Asia. Revenue then doubled in two years, to €8 million in 2021, and the company began bringing work back: high-end speakers, priced from €2,000, were again made in Soissons — about 20 of its 70 models — and a US subsidiary in New York State had reached €1 million in revenue, the paper said.

Today Triangle is unusually plain about where its products are made. Its manufacturing policy says the Magellan 40th, Signature, Esprit 40th and Capella ranges “are entirely manufactured on our premises,” while “assembly of our other loudspeaker ranges is outsourced to Asia,” where it says it keeps an office of engineers and quality controllers at its subcontractor. That is the company’s statement; it matches the Gazette’s account and Son-Vidéo’s 2017 report that the Soissons site assembled the Magellan and Signature ranges. A 2012 Fnac article said Triangle made all its speakers itself; we do not repeat that as current.

For a design guide, Triangle shows how a brand can be honest about a split between a home workshop and outsourced assembly. Compare Cabasse, the Brest coaxial specialist, and Davis Acoustics, another French loudspeaker maker. For this guide we use walnut, stone and a red accent with a geometric sans, an unofficial interpretation; no product or logo is reproduced.
