Model Nine is a much loved flagship loudspeaker originally developed in the 1950’s by KLH’s founder Henry Kloss and Engineer, Arthur Janszen.
“Between the period of 1957 to 1959, JansZen Labs developed full-range electrostatic prototypes that so attracted the attention of KLH that the company made Arthur Janszen a buy-out offer he couldn’t refuse. In short order JansZen Labs’ assets were transferred to KLH and Janszen became a Vice President there. He continued work on what was to become the KLH Model Nine, a spare-no-expense flagship product.”
