Two young men, a garage and a trade licence.

d&b audiotechnik began on 18 April 1981, when Jürgen Daubert and Rolf Belz registered a business in Korb, a wine village near Stuttgart. The company’s own history says they filed the papers at the town office in nearby Waiblingen under the name “d & b Audiotechnik” — the initials of the two founders — and that the spaces were soon dropped and the whole name set in lower case. That lower-case “d&b” is still how the company writes itself, and it is the easiest thing about the brand to get wrong.

The first loudspeakers were built in a garage. A chronicle on the company’s website in 2016 says they went mainly to hire companies and musicians, and that one early system was the house rig for the Stuttgart club MAXIM. In 1984 the business moved to a larger garage on Steinstrasse in Korb, and in 1985 it put its first complete product line on the market, the F1, F2 and B1. The chronicle calls them “the black boxes from Korb,” and says the German rock singer Herbert Grönemeyer took them on tour.

Broadcast and theatre work followed. The E1 of 1986 was a small loudspeaker meant for television studios, and the 1220 system of 1988 became, in the company’s words, a reference for theatre and opera — d&b’s first step into permanent installations. In 1989 the Korb premises had grown too cramped and d&b moved 25 km to Backnang, a town the chronicle describes as the leather capital of south-west Germany. German Wikipedia also gives lack of space as the reason for the move. The company’s present website says its headquarters settled in an old spinning mill there.

Offices abroad came quickly: Scandinavia and the UK in 1989, Italy in 1996, the United States in 1998, Japan in 1999, and France and Spain in 2000, according to the chronicle.

C4, Q, J, V and GSL.

d&b’s reputation in touring rests on a run of systems that sound engineers learned by their letters. The C4 of 1994 quickly became standard touring equipment, the chronicle says, and the P1200 amplifier of 1993 earned a name for reliability. The E-PAC of 1997, a mono amplifier with a built-in controller, marked d&b’s move into digital signal processing; the Q-Series followed in 2003, the J-Series large-scale line array in 2006, and the mid-sized V-Series at Prolight + Sound in Frankfurt in 2012. The flagship GSL system, part of the SL-Series, was introduced at Prolight + Sound in 2018, according to the company and trade titles including ProSoundWeb and Audio Media International.

The idea underneath is what the company calls System reality. d&b says its loudspeakers “can only be driven by d&b amplifiers,” an exclusive pairing it presents as a technical benefit; amplifiers, loudspeakers, rigging and software such as the ArrayCalc simulation tool and the R1 remote control are sold as one system. Its stated mission, which it calls “Democracy for listeners,” is that every seat should hear the same quality of sound.

Awards are mostly trade honours. The chronicle lists the ABTT Product of the Year Sound Award for the E8 loudspeaker in 2008, and for the V-Series in 2012; in 2010 the B4 cardioid subwoofer, which shapes its pattern with its cabinet rather than with active processing, won a Live Design award, a PLASA Innovation Award and a ProSoundWeb readers’ award. In 2011 d&b added a White range of sixteen integration loudspeakers beside its Black range — the plainest statement of the brand’s visual side, in which the finish is chosen to disappear into a room.

In April 2026 d&b, its rival L-Acoustics and the software maker SoundPLAN presented a shared file standard for sound-system design, called SDE (System Design Exchange), according to a d&b press release.

The touring PA trade.

Concerts and festivals are amplified by a few specialist loudspeaker makers. English Wikipedia credits L-Acoustics, founded by Christian Heil in 1984 and based at Marcoussis, south of Paris, with the V-DOSC line source array of 1992, and says most makers have since adopted the line array — a column of linked cabinets — for touring.

France has a second maker. Nexo, founded in 1979 and based at Plailly, north of Paris, says Yamaha completed its acquisition in 2008 and that its cabinets are designed and made in France. Germany’s d&b audiotechnik, founded in 1981 by Jürgen Daubert and Rolf Belz, is based in Backnang, near Stuttgart; the Paris private-equity firm Ardian bought it in 2016, Providence Equity Partners announced a significant investment in 2023, and the company says its products are handmade there.

Two are British. Martin Audio, founded by Dave Martin in 1971, is based in High Wycombe and was bought by Focusrite plc in December 2019, the companies announced. Funktion-One, formed in 1992 by Tony Andrews and John Newsham after they left Turbosound, is based near Dorking, Surrey, and English Wikipedia lists Berlin’s Berghain among the clubs using its systems.

In North America, Meyer Sound was founded in 1979 by John and Helen Meyer and is based in Berkeley, California. Adamson, which dates itself to 1984 in Vancouver, says it makes its systems at its own plant in Port Perry, Ontario.

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.

Three private-equity owners in twelve years.

The founders’ company has changed hands three times. In 2011 the investment firms Odewald & Compagnie and COBEPA acquired d&b, according to a d&b press release of March 2016; the sources we checked do not say who sold. Under them, the release says, sales more than doubled from €44 million in 2011 to €94 million in 2015, staff rose from about 200 to about 350, and production capacity more than doubled.

On 1 March 2016 d&b announced that Ardian, the Paris-based private investment company, was buying it from Odewald and COBEPA, with the management team, then led by chief executive Amnon Harman, taking a stake. On 10 July 2023 the company announced a significant investment by the American private-equity firm Providence Equity Partners, again with management co-investing and terms undisclosed, subject to competition approval; Ardian’s release the same day described it as a sale of the d&b Group. d&b said that since 2016 its revenue had tripled and its workforce had grown from 350 to more than 1,000. The group now has two brands, d&b audiotechnik for audio and d&b solutions for integrated audio, video, lighting and media work. In December 2025 it bought its long-time Scandinavian distributor, the ARVA Group. The company’s website now names Jaakko Kaivonen, formerly its chief revenue officer, as chief executive.

Where it is made is a clear claim. The website says its products are “conceived, handmade and dispatched globally” from Backnang, and German Wikipedia says d&b develops and produces its products mainly there; the 2016 chronicle records new production halls in 2008 and a new loudspeaker assembly line at the end of 2012, and German Wikipedia says production and logistics space grew to 30,000 square metres in 2023. One naming trap: d&b is not related to dBTechnologies, the Italian powered-speaker brand of the RCF group. Ardian’s 2023 release says d&b was founded in Backnang; its own history places the start in Korb.

For a design guide, d&b audiotechnik shows how a brand can be built on discipline rather than display: black boxes, a white range that hides, and a name kept in lower case for four decades. Compare Powersoft, the Florence amplifier maker, and dBTechnologies. For this guide we use black, white and a deep red with a sans, an unofficial interpretation; no product or logo is reproduced.
