GGNTKT (pronounced 'Gegentakt,' meaning push-pull in German) is an innovative German audio technology company founded in 2018 by Roland Schäfer as a trademark of Roland Schäfer Elektroakustik und Audiotechnik, headquartered at Luise-Albertz-Str. 2, 53340 Meckenheim, Germany, specializing in the design and production of evidence-based digital active loudspeakers for immersive sound experiences and realistic audio reproduction. Founded by Roland Schäfer, a career changer who transitioned from an agency background to pursue his passion for active hi-fi loudspeakers, GGNTKT emerged as a young German brand from western Germany with close connections to the renowned technical university RWTH Aachen, assembling a diverse team of acousticians, electrical engineers, industrial designers, software specialists, and craftsmen united by their commitment to scientifically-verified audio engineering. The company's philosophy centers on evidence-based design methodology, utilizing complex technologies including waveguides, cardioid radiation patterns, and advanced FIR (Finite Impulse Response) filters, with all designs optimized according to current scientific knowledge and verified through extensive simulations, measurement series, and validation by Klippel audio measurement technology to achieve authentic 'you-are-there' sound reproduction effects. GGNTKT's product lineup includes the iconic Model M1 (launched 2019), a compact 2.5-way active loudspeaker with waveguide and cardioid bass for short to medium listening distances; the flagship Model M3, a 4-way active floorstanding speaker system available in standard (1000W) and S variants (1500W) powered by four efficient Class-D amplifier channels via two PASCAL pro audio modules for demanding high-end audio rooms, studio productions, and mastering applications; and the Model S1, a self-powered in-wall 2-way custom installation design for home theaters and professional multichannel monitoring. Operating under the 'Made in Germany' quality standard with a commitment to long-term product support through regular firmware updates, GGNTKT pursues the same goals as prestigious brands like Kii Audio, Grimm Audio, and Dutch & Dutch, excelling in purity, naturalness, and musicality while challenging traditional passive loudspeaker designs with their active, digitally-optimized approach to high-fidelity audio reproduction. The company maintains direct customer relationships through phone support (+49 (0) 22 25 - 99 89 689), email ([email protected]), demonstration bookings, and social media presence on Facebook and Instagram (@ggntktaudio), while participating in major audio industry events like the HIGH END show and Norddeutsche HiFi-Tage, representing a new generation of German audio engineering that combines cutting-edge digital signal processing, precision acoustics, and artisanal craftsmanship to deliver immersive sound experiences for recording studios, home theaters, and discerning audiophiles worldwide.
