Die akustikplus GmbG & Co. KG ist Spezialist für hochwertige, designorientierte Akustiklösungen aus Holz. Das Unternehmen entwickelt und produziert akustisch wirksame Wand- und Deckenpaneele, die Funktionalität und Ästhetik auf anspruchsvolle Weise verbinden. Von der Hamburgs Elbphilharmonie, über das Rathaus der norwegischen Kulturhauptstadt Bodø bis zur größten Indoor Radrennbahn, dem Velodrome in Dubai - Architekt:innen, Planer:innen und Innenausbauer:innen weltweit setzen auf die Produkte von akustikplus zur klanglichen und gestalterischen Optimierung von Räumen.

Seit April 2021 gehört akustikplus zu den Hamberger Industriewerken. Mit der Übernahme wurde der zukunftsorientierte Bereich der Raumakustik in den Konzern eingebunden und das Portfolio damit strategisch erweitert. Boden, Wand und Decke gibt es nun aus einer Hand.

Im Jahr 2023 erfolgte der Umzug vom bisherigen Standort in Thüringen nach Stephanskirchen, wo akustikplus nun räumlich und prozesstechnisch in den Hamberger-Konzern integriert ist. Diese Zusammenführung schafft zahlreiche Synergieeffekte: So profitiert akustikplus heute von gemeinsamen Logistikstrukturen, zentralem Einkauf, SAP-gesteuerten Bestellprozessen und einem professionellen Produktionsumfeld.

Gleichzeitig behält man ein eigenständiges Markenprofil und steht wie seither für "Raumklang in Perfektion".

The company has operated its own agricultural business – the Gut Filzenhof agricultural estate – since 1916. The business was originally dedicated to rearing dairy cattle until the seventies when the focus shifted to the fattening of young bulls. The highest quality meat and sausage fare is marketed directly via the farm shop at Gut Filzenhof. Quality-conscious customers from the region and beyond have been enjoying the direct distribution service for many years. As an EU-approved business, Gut Filzenhof guarantees an openness on which trust can be built. The entire operation is subject to continuous EU controls. The safety of the foodstuffs is furthermore guaranteed by ongoing hygiene inspections and own monitoring mechanisms. Alongside this, the company also has a direct link to the raw material wood through its own forestry operation.
