A three-way loudspeaker at a Vienna hi-fi fair.

Lumen White’s beginnings are easiest to date from the outside. Dirk Sommer, editor of the German online magazine hifistatement.net, wrote in May 2015 that “more than 15 years” earlier he and a colleague had discovered the first product of the then-unknown company at the annual hi-fi fair in Vienna: the White Light, a three-way loudspeaker. The company’s own website dates the introduction of its loudspeakers to 1999, which fits. Sommer reviewed one of the first pairs and ended up buying it; about five years later, he wrote, a pair of Diamond Lights replaced them as his personal and professional reference.

The designer is named in the same reviews. Sommer’s German review and its English version in Positive Feedback, published in October 2016, credit Hartmut Roemer as the Lumen White designer “who already envisioned and developed the company’s loudspeakers,” and later its turntable. Neither the company’s website nor the other sources we checked give a founding date, a founding team or a first address, so we do not give one.

The name is written two ways. The company styles itself in lower case as “lumen white research,” while its web address and some reviewers, Sommer among them, run the words together as “LumenWhite.” Its early website, which the Internet Archive first captured in 2001, carried the title “lumen white – ultra precision transductors.”

Ceramic, diamond and tonewood.

The White Light was joined by the White Flame, and in November 2005, according to a company announcement preserved by the Internet Archive, by two new models: the Diamond Light, a “limited production” flagship, and the Silver Flame, which the company described as its core technologies transferred to “a premium quality industrial production design” at a lower price. From that date, it said, the White Light and White Flame would come with pure diamond tweeters as standard.

The ingredients have stayed consistent. On the company’s current pages the Diamond Light is a five-driver, three-way design with a 1.2-inch diamond tweeter and ceramic inverted-dome midrange and bass drivers, standing 137 cm tall and weighing 90 kg, in cabinets the company says use “premium woods, no mdf.” Newer models — the Kyara, the Altai, the White Light III and the 171 cm Annapurna — pair ceramic or diamond tweeters with cabinets of what the company calls “instrument-grade plywood” made from several tonewoods. It presents the speakers as musical instruments as much as machines, and its website links to articles on the violins of Cremona.

The company also makes a turntable, the Mystere, which appears on its website in the Internet Archive by 2014. It has an air-bearing platter and a separate compressor and controller; Positive Feedback listed it at €62,500 in 2016, and Sommer reported that most units had gone to buyers in the Far East.

Much of the brand’s reputation rests on reviews it quotes itself. Its website says Japan’s Stereo Sound gave the White Light its Grand Prix in 2002 and later gave one to the Diamond Light; that Germany’s stereo called the White Light “the best loudspeaker we know”; and that the French magazine Diapason gave the Kyara its “Diapason d’Or” in its June 2025 issue. We give these as the company’s reports.

Design and documentation.

Europe has a layer of very small makers whose products are built in small numbers and sold at very high prices. Five of the seven brands in this round are Swiss; the other two are Greek.

The Swiss five are spread across the country. The Swiss commercial register, Zefix, lists Stenheim Suisse SA with its seat in Vétroz, in the canton of Valais; FM Acoustics Ltd in Egg, near Zurich; and Daniel Hertz SA, the company associated with the audio engineer Mark Levinson, in Milvignes, in the canton of Neuchâtel. Boenicke Audio is registered in Basel as a sole proprietorship, and its website is signed by Sven Boenicke.

Lumen White, a loudspeaker maker that dates its speakers to 1999, now gives a contact address in Lucerne; in 2017 its website named a London address for its group and Lucerne for research and development.

The two Greek makers are both in Attica. Ypsilon Electronics says it was formed in 1995 by two sound engineers and gives an address in Paiania, east of Athens; Ideon Audio, founded in 2016, gives an address in Nea Filadelfia.

What links them is scale and price rather than place. At the top of these ranges prices run high — Part-Time Audiophile listed Ideon’s Absolute ε DAC at $47,000 in 2024 — and some runs are tiny: Ideon says its 2026 Ayazi anniversary edition is limited to 20.

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.

Austrian ties, a Swiss address.

The brand’s business ties run through Austria. Sommer’s reviews name Gerhard Hirt, the head of the Austrian amplifier maker Ayon Audio, as Lumen White’s world distributor, and in a 2017 interview series published by Positive Feedback, the Polish editor Wojciech Pacuła introduced Hirt as “the founder and owner of Ayon Audio, co-owner of Lumen White.” Lumen White’s website today says its world distribution is coordinated by Living Sound Vertriebs GmbH in Gratkorn, near Graz — the street address Positive Feedback gave for Ayon in 2016 — and its American arm shares an Arizona address with Ayon’s US office. Ayon’s news pages show the two brands exhibiting together in Vienna and Warsaw in 2026.

The company’s own address, however, is not Austrian. Its contact page gives lumen white research at an address in Lucerne, Switzerland, and its privacy notice, dated May 2024, names a data-protection office in west London. Its product pages say the speakers are “designed in switzerland” and “manufactured in the eu,” without naming a factory; we give that as the company’s claim, and we could not find the legal entity behind the name in the Swiss commercial register. So “Austrian” is only part of the story: the brand was first shown in Vienna, is distributed from Austria and, as of 2017, was part-owned by an Austrian, while it now describes itself as designed in Switzerland.

It is still active. Its news page listed the HIGH END show in Vienna in June 2026, and Ayon announced the Annapurna’s premiere for the Warsaw show in October 2026.

For a design guide, Lumen White shows how a small brand can build its identity on materials — tonewood, ceramic and diamond — and on the words of its reviewers. Compare Vienna Acoustics, another loudspeaker name tied to Austria, and Piega, a Swiss loudspeaker maker. For this guide we use midnight navy, a lacquer red and maple with a serif, an unofficial interpretation; no product or logo is reproduced.
