Acoustics Lab

Established in 2016 but its history is dating back to 1975 when Chario® Loudspeakers was founded.

During past decades spent on electroacoustic engineering we were also studying audio perception as a necessary tool to match theory to listening.

Chario® Psychoacoustics Lab has been recognized to be a trusty independent research laboratory thanks to his remarkable studies on Home Listening.

During almost forty years of R&D we have been dealing with most of the topics about acoustical events in small rooms.
