Hommage T1

Introduced 2006$4,695 MSRP

Auditorium 23 is a small German maker run by designer Keith Aschenbrenner, hand-winding step-up transformers and building loudspeakers in small numbers with a narrow specialist-dealer network rather than wide retail. The Hommage T1 was A23's first "statement" product line entry, developed by Aschenbrenner after studying and dismantling vintage transformers including a Western Electric 618B, intended as a companion piece to the marque's SoloVox loudspeaker; it is distinct from the more affordable Hommage T2 already in this catalog.
