A musician, a city and panels built to order.

GIK Acoustics was founded in 2004 in Atlanta, Georgia, by Glenn Kuras, a musician, the company says. A press release it issued from Atlanta on January 14, 2014, to mark ten years in business put it plainly — “Glenn Kuras started GIK Acoustics in Atlanta, GA, in 2004” — said he had founded the company “on a philosophy to provide quality products AND quality information,” and quoted him as “Owner and President.”

The earliest version of its website archived by the Internet Archive, captured in July 2005, sold a single argument: that acoustic foam absorbs only high frequencies, “leaving your room dead sounding,” and that serious rooms need broadband absorption. Its FAQ of early 2006 explained the low prices by saying the company kept little stock — “pretty much all panels are built to order” — and described a four-inch mineral-fibre panel with its wooden frame on the back, acting as a spacer, rather than on the sides, where the company said it would reflect sound. Fabric came in black or natural white canvas.

Expansion came within four years. In 2008 GIK Acoustics–Europe opened in Bradford, in West Yorkshire, England, “bringing local manufacturing and support to European customers,” according to the company’s timeline. The 2014 release named David Shevyn as its general manager and partner; in 2026 the company called him its head of Europe. UK company records list Kuras and Shevyn as directors of the present British company, GIK Acoustics Europe Ltd, incorporated in Bradford in 2019, with Kuras recorded as the person with significant control. In the sources we checked there is no sign of an outside owner: GIK appears to remain a founder-led private company.

Bass traps, diffusers and a patent.

GIK sells direct and builds to order. Its frequently asked questions page says orders for the Americas are “made and shipped from our Atlanta, Georgia facility,” orders for the European Union are “built and shipped from our Kielce, Poland facility,” and orders for the UK and the rest of the world are fulfilled from Bradford. Its about page says every product is built “in our own facilities in the US and Europe,” by hand and to the customer’s specification, which is why lead times run to weeks. We give those as the company’s own statements; we have not visited the workshops, and we could not establish when the Polish workshop opened.

The range grew from plain absorbers into bass traps and diffusers. By 2014 the catalogue included the 242 Acoustic Panel, the 244 Bass Trap, the Monster Bass Trap, the Tri-Trap corner trap, the Soffit Bass Trap — launched in 2010, the company says — the Scatter Plate, Scopus tuned-membrane traps and the Q7d diffusor. Its FlexRange system, a two-frame absorber design, received US patent 9,091,060 in 2015, the company says. Then came the Alpha Series of hybrid absorber-diffusers in 2018, modular Sound Blocks in 2022, the TurboTrap with what GIK calls Dual-Density Material in 2023, and the Amplitude panels, whose recessed front plate it says was patented in 2025. In 2016 it launched a “Greensafe” initiative, committing its products to ECOSE insulation, recycled content and formaldehyde-free binders.

Independent reviews have been broadly warm. Sound On Sound’s Paul White tested the Evolution PolyFusor, a curved diffuser with absorbent fill behind it, in December 2015. The magazine’s February 2024 review of the SlatFusor, by Sam Inglis, called it an “ingenious new design” that “provides both absorption and diffusion, at a highly affordable price.” And in February 2026 Neil Rogers, reviewing the PIB Pack portable vocal booth for the same magazine, wrote that GIK had “established themselves as arguably the most prominent alternative source of acoustic treatment to studio professionals and home recordists.”

Rooms as instruments.

The seven brands here make the same kind of thing: objects that change how a room sounds. Absorbers soak up reflections, bass traps tame low frequencies, and diffusers scatter sound rather than remove it. Customers run from recording studios to home cinemas.

Four are North American. GIK Acoustics was founded in Atlanta, Georgia, in 2004 by the musician Glenn Kuras; it says its panels are built to order in Atlanta and, for the EU, in Kielce, Poland, with UK orders fulfilled from Bradford, England, where its European arm started in 2008. Auralex, which Eric Smith says he founded in his garage in 1977, is based in Indianapolis. Primacoustic, in Port Coquitlam, British Columbia, began in 2000 as a division of Radial Engineering; Radial says its founder, Peter Janis, sold the company to Regimen Equity Partners in 2018.

RPG, which Peter D’Antonio founded in 1983 around what it calls Reflective Phase Grating diffusors, now trades as RPG Acoustical Systems, LLC, from Passaic, New Jersey, its website says.

Three are European. Vicoustic was founded in Portugal in 2007 and has its headquarters and research centre in Paços de Ferreira; the brand is owned by Visound Acústica SA, and in 2026 it said it had joined forces with United Acoustic under the name UniVicoustic. Artnovion is run by Artnovion Lda, a Portuguese company whose EU-funded projects are registered in the country’s Norte region. t.akustik is the house label of Thomann, the family-owned music retailer in Treppendorf, Bavaria.

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 brand built on room advice.

GIK’s public identity rests less on a mark than on advice. From its early years the website carried a downloadable acoustics primer, articles and videos on room problems, and an offer of free room recommendations; today it describes a team of acoustic designers who give free consultations, alongside a 3D room designer, a panel calculator and a product-comparison tool. Fabric now comes from Camira’s Cara range, which Sound On Sound also noted in 2015. The company says it has served more than 129,000 customers.

The look of the products has moved with the catalogue. Early panels were plain fabric-wrapped slabs; the SlatFusor and Amplitude lines add slats, felt and flush front plates, and GIK now sells framed art panels and diffusers in wood finishes. The common thread is utility — sizes, depths and colours chosen by the buyer — rather than a single signature object.

A note on addresses: the European shop runs at gikacoustics.net, to which gikacoustics.co.uk redirects; gikacoustics.eu, when we checked in October 2026, showed an unrelated maintenance page.

For a design guide, GIK Acoustics shows how a direct-selling maker can build a brand on education and made-to-order work rather than on a famous logo. Compare Primacoustic, the Canadian panel brand started by a pro-audio company, and Genelec, whose monitors fill the kind of rooms GIK treats. For this guide we use charcoal, fabric grey and an amber with a sans, an unofficial interpretation; no product or logo is reproduced.
