A special highlight in the speaker scene is Proraum's large "Anechoic Chamber" - a cube of 7.3 m with 70 Hz cut-off, which has been available since 1990 in the newly-built company facilities. The instrumentation of the laboratory is complete with the outstanding measurement devices from Bruel & Kjaer, MLSSA Analyzer and the excellent listening studio after German IRT (Broadcast technology) guidelines. These optimal development conditions guarantee to provide our customers a first-class environment for very high-quality testing, supporting measurement materials and unsurpassed final production guidelines.


Internationally the proraum-chamber is one of the largest test venue in today's speaker industry. Developments for SONY-Germany and Japan, leading to several highlight reviews, have been done successfully in this facility.
