Fabrizio Sorbi’s start.

Proel began with cables. The company says it was founded in 1991 by Fabrizio Sorbi, first “producing assembled cables,” the leads that connect sound equipment, and it marked 35 years in 2026. It is based at Sant’Omero, in the province of Teramo in the Abruzzo, and is a joint-stock company, Proel S.p.A., with share capital of €8 million; we found no published accounts, so the history here is the company’s own.

Its timeline describes steady expansion. It set up its own research and development department in 1997; bought the drum maker Tamburo, founded by Tullio Granatello, in 1998; bought the lighting brand Sagitter, founded in 1992, eleven years later, in 2003; and, in 2007, bought the British loudspeaker maker Turbosound. We found no reliable record of what became of Turbosound afterwards within Proel, so we state only the purchase.

In 2012 it introduced NEOS AXS loudspeakers and launched Axiom, its professional-audio brand, which added column arrays in 2018.

A Roland plant and a piano brand.

One Proel purchase links it to the history of Italian electronic instruments. In 2015, the company says, it bought the former Roland Europe plant in Italy, about 25,000 square metres, and 25 former Roland staff launched Dexibell, a digital-piano brand, within the group. Roland’s European production company in Italy dated from 1987, according to Roland’s own history, and Roland also lists an Italian sales partner from 1986. Italian sources link the production company’s origins to Siel, the synthesizer maker founded in 1976 at Acquaviva Picena, in the Marche, by the former Farfisa designer Carlo Lucarelli, whose Orchestra keyboard ARP sold in the United States as the Quartet. Proel does not say where the plant it bought stands, and we do not assume it was Siel’s.

The company has also built abroad. It says it opened a production facility in Tunisia in 2016, without naming its location, expanded into the United States and Canada in 2017, and in 2019 opened “ON&ON,” an 800-square-metre test theatre. In 2022, it says, it began making the Fisa Suprema digital accordion for Korg, the Japanese instrument maker. It has subsidiary companies in Santa Clarita, California — Proel North America — in London, as Proel International, and in Korea, as Proel Korea.

Its brands now cover sound, light and instruments: Proel Soundsystems and Proel Stage Equipment, Axiom, Sagitter and SDJ lighting, Eikon microphones and headphones, Italian Stage, Dexibell, Tamburo and Grassi wind instruments.

The groups.

Italian professional audio has been consolidating into groups. RCF Group of Reggio Emilia, which also owns dBTechnologies, bought the American loudspeaker maker EAW and the Danish microphone maker DPA in 2018–19 and the Italian PA brand Montarbo in 2019; in 2019, according to Il Sole 24 Ore, it had about 700 staff, exported 87 per cent of its sales and planned a stock-market listing it later withdrew.

A second cluster has formed around Florence. The amplifier maker Powersoft of Scandicci, listed in Milan since December 2018, bought 51 per cent of the loudspeaker maker K-array of Scarperia in 2025, on an enterprise value of €50 million, with the deal announcement stressing the two companies’ “territorial proximity.” Nearby, the listed transducer maker B&C Speakers, founded in Florence in 1946, reported revenue of €100.4 million in 2024 and has bought Eighteen Sound of Reggio Emilia and Eminence of Kentucky, according to Italian Wikipedia.

The groups reach well beyond Italy. RCF Group’s EAW is American and DPA Danish; Powersoft has a subsidiary in New Jersey and earned 44.2 per cent of its 2025 revenue in North America; and B&C Speakers, listed in Milan since 2007, bought Eminence Speaker of Kentucky in September 2023 and its operations in Dongguan, China, that December, according to Italian Wikipedia.

Ownership has moved between these firms as well as into them. Montarbo, the Bologna PA maker, was controlled by Eko Music Group of Montelupone, in the Marche, by 2012, and passed to RCF Group’s AEB Industriale in January 2020. FBT of Recanati, founded in 1963, is controlled by a holding company that bears the name of Vinicio Tanoni, and Proel of the Abruzzo was founded in 1991 by Fabrizio Sorbi, who started with cables. Each company describes where its products are designed and made in its own words, and the guides below quote them.

Proel built a group of its own the other way — not by joining one, but by buying brands across sound, light and instruments.

PROEL in red capitals.

Proel describes its approach as “Development, design and production come together… always in the name of Made in Italy,” and calls itself “Engineered in Italy, present in over 100 countries.” Because the company also describes a production facility in Tunisia and manufacturing for Korg, we use its own phrase — engineered in Italy — rather than claiming everything is made there.

Its website sets the name PROEL in capitals and uses a strong red, held in its stylesheet as the brand’s red, #E31E24, with the Archivo grotesque and JetBrains Mono, a typeface designed for programmers. That is the website’s styling; we found no published brand manual. The company does not say whether Fabrizio Sorbi still leads it. We give Proel’s timeline as the company’s own account, since we found no independent coverage of its purchases in the sources we checked. We found no staff or revenue figures on its websites, which include proelworld.com for the group, proel.com and axiomproaudio.com.

Proel has also tried to buy other Italian names. When the toy-keyboard maker Bontempi’s trademark was sold in 2015, a bid from Proel was rejected, according to the newspaper Il Centro; the mark went to iCom of Ancona instead, for about €1 million, when Bontempi still had 94 employees.

For a design guide, Proel shows a group that keeps many separate brand names under one parent. Compare Siel, whose story leads to the Roland plant Proel bought, and RCF, another Italian audio group. For this guide we use the website’s red and a graphite with a sans, close to the company’s own but an unofficial interpretation; no product or logo is reproduced.
