Romanticum is a permanent exhibition about the German Romanticism Period in the city center of Koblenz. The visitors experience a three-dimensional sound trip to the legendary Rhine Valley covering the entire exhibition space, where they acoustically cruise on a 19th-century steamboat. Boarding at dawn at the awakening harbor, steering along the river banks, and into the magical night hours spellbound by Lorelei, a famous local female water spirit, the sonic journey provides a humorous backdrop to the exhibits and informative text presented in the exhibition. THE SOUND OF THE MOUNTAIN developed the technical concept for the spatial loudspeaker array; the MNTN Production Suite was used to produce all audio content.
