Proraum – Your Partner for Excellent Loudspeakers
Audax - Auris - BG Corp. - DEQX

Proraum Vertriebs GmbH was founded in October 1980. In the year 1981 Rainer Krönke was hired as a shareholder and development-engineer. The love of electro acoustic transducers appeared early in Rainer Krönke youth, and was therefore the basis for what turned out to be an area of superior expertise. Training as a sound engineer and working at the prestigious Hansa (by the wall) Recording Studios, as well as years of experience in the Hi-Fi scene and speaker development, resulted in an extraordinary know-how and professionalism. The quest for absolute perfection and high quality requirements turned out to the guidelines to his success.

Therefore, Professional speaker development since that time became the heart of the business of Proraum GmbH and is now based in Bad Oeynhausen, Germany (North Rhine-Westphalia).

Here you will find highly regarded brands like Audax - Auris - BG Corp. and DEQX.
