An American speaker, a Turin importer and a new name.

Indiana Line’s story starts with another company’s speakers. According to the Italian hi-fi site Audio 2G, writing in April 2024, the Turin company Selectra — which also owned the Revac brand — imported loudspeakers made by the American firm Utah. To cut the cost of shipping and customs it began importing parts and assembling the speakers in Italy. Hi-Fi Pig, in a January 2026 review, put it the same way: because the cabinets were so expensive to import, the Italians brought in the drivers and built the large cabinets themselves.

When Utah went out of business in the United States, the Italian operation carried on. Audio 2G says that Alcor, which had taken over from Selectra, kept production going under a new name, Indiana Line. “The name was a kind of tribute to the old Utah,” it wrote: one American place name replacing another. The company itself dates the brand to 1977 — its 2022 Italian catalogue opens “Nata a Torino nel 1977,” born in Turin in 1977 — while the Italian press accounts speak more loosely of the 1970s, so we give the company’s date as its own.

From the start the brand sold on value. The catalogue describes its founding principle as “the search for the best possible sound for the price,” names early models such as the Mini xa, 1xa, 2x, 3xa, 4xa and BMx, and says the slogan “piacere d’ascolto” — the pleasure of listening — ran in its advertising from the first.

Coral Electronic and the value series.

The brand’s second Italian owner was a speaker specialist. In 2006, the company’s catalogue says, Indiana Line was bought by Coral Electronic, “another historic company of Italian hi-fi,” founded by Eugenio Musso. Sources differ on the details: AF Digitale, interviewing the brand’s chief executive in March 2021, gave the takeover as 2007, and while the catalogue says Coral was founded at the end of the 1960s, a company database lists Coral Electronic S.r.l. as registered in June 1975, at an address in the province of Turin, and now in liquidation. The catalogue says the deal let Indiana Line combine Coral’s know-how in designing drive units with its own experience of designing complete speakers.

Under Coral the range settled into the families that still carry the name. Nota is the entry series, Tesi sits above it and Diva above that, with Basso subwoofers and in-wall and installation models alongside. The 2022 catalogue describes cabinets of MDF, midrange cones of Curv, a woven, heat-pressed polypropylene, woofer cones of unpressed long-fibre cellulose and silk-dome tweeters, with simple low-order crossovers so that the speakers are easy for modest amplifiers to drive.

The catalogue is also frank about looks. Its design motto, roughly translated, is “We don’t have to impress anyone, and we don’t have to be ashamed in front of anyone,” and it promises “no flourishes” — plain, timeless boxes meant to sit in a room without drawing attention. The current website speaks of “Italian design traditions” and architectural influences, but the cabinets themselves remain plain rectangular boxes.

The value message has held up in reviews. In March 2025 the webzine TNT-Audio called the Tesi 2 bookshelf speaker “incredibly mature and balanced,” and Hi-Fi Pig gave the Utah 5 floorstander, priced at £699, five hearts in 2026. That model revives the name of the American speakers the brand grew out of.

Design and documentation.

Italian hi-fi has long been judged on looks as well as sound. In the 1960s the Milan maker Brionvega worked with designers such as Marco Zanuso and Richard Sapper; its Doney television won the Compasso d’Oro in 1962, and in 1970 the award went to the company itself, according to Italian Wikipedia.

The loudspeaker story usually begins with Sonus faber, founded by Franco Serblin in 1983 and based at Arcugnano, outside Vicenza. Serblin left in 2006; in 2007 the brand passed to the Fine Sounds group, renamed McIntosh Group in 2016, and in November 2024 Bose announced it was buying McIntosh Group, Sonus faber included.

Italian magazines such as Audio Review and Fedeltà del Suono review the country’s equipment, and makers launch products at shows in Milan and at HIGH END, held for many years in Munich and, from 2026, in Vienna.

The makers in this guide are spread out. Franco Serblin’s studio gives its home as Vicenza; Rosso Fiorentino is at Bagno a Ripoli, outside Florence; Albedo’s maker is at Montelabbate in the Marche; Zingali is at Aprilia, south of Rome; and Indiana Line, a Turin name since 1977, has been owned since 2020 by the Polish distributor Audio Klan, Italian trade press reports. Riviera Audio Laboratories is named for the Ligurian coast its founders call home but is registered at Pozzuoli, near Naples. Diesis Audio is in Umbria, at Castel Ritaldi near Spoleto, according to its website and business-registry summaries.

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.

An Italian name, a Polish owner, a Chinese factory.

In 2020 the brand left Italian ownership. The company’s website says that Audio Klan, “the brand’s most successful distributor,” acquired Indiana Line that year, after 43 years in Italy. Audio Klan is a family-owned Polish company founded in 1994 that began as a distributor with a showroom in central Warsaw, according to its own website, and also runs the Top Hi-Fi & Video Design shops; TNT-Audio described Indiana Line in January 2025 as “now owned by Audio Klan in Poland.” In Italy the brand was run after the sale by Marco Visonà as chief executive, according to AF Digitale, with logistics handled from Bologna.

What changed next was where the speakers are developed. In 2021 Visonà told AF Digitale that design and product development would stay in Italy. The brand’s website now says something different: Indiana Line is “now developed by a skilled research and development team in Poland, working closely with Italian experts.” We give both as stated, and take the website as the current position.

Where the speakers are built is a separate question, and the company’s pages we checked do not answer it. Reviewers do. TNT-Audio wrote in 2025 that “the design as usual is Italian, while the manufacturing is Chinese,” and Hi-Fi Pig described the Utah 5 in 2026 as combining Polish research and development and Italian engineers with manufacturing in China. That makes Indiana Line a different kind of Italian brand from the small workshops elsewhere in this guide: a Turin name, kept alive by a Polish owner and built to a price in Asia.

The website today is published in Italian, English, Polish, German, Hungarian and Czech, and names Poland and Italy as the brand’s strongest markets.

For a design guide, Indiana Line shows how a brand name and its origin story can outlast the companies and countries behind it. Compare Chario, another long-running Italian speaker name, and Opera Loudspeakers. For this guide we use a dark blue, walnut and cream with a sans, an unofficial interpretation; no product or logo is reproduced.
