Auditorium 23

Auditorium 23 is a German high-end audio manufacturer founded in the early 1980s by Keith Aschenbrenner, based in Frankfurt/Schwalbach, Germany. The company specializes in handcrafted, musically-oriented audio equipment including loudspeakers (like the sought-after Solovox series), step-up transformers for moving-coil cartridges, and speaker cables. The company emphasizes traditional materials and construction methods over modern cost-cutting approaches, with a philosophy focused on musical reproduction rather than technical specifications.
