With the horizontally oriented Oberon Vokal center speaker, any Oberon speaker configuration can be expanded into a powerful surround system. The Oberon Vokal, with its 44 cm wide cabinet, can not only be integrated into most hi-fi furniture but can also be easily placed on a shelf below or above the TV screen. To allow for space-saving placement directly against the wall, its bass reflex port is integrated into the front baffle, unlike all other Oberon models.

For clear, detailed, and powerful reproduction of all voices, the speaker features a 29 mm large, extremely lightweight Oberon textile dome and two 130 mm (5 1/4'') mid-woofers with wood fiber membranes and SMC magnetic systems. Since the Oberon Vokal is acoustically matched to the other speakers in the series, a harmonious and cohesive sound image for the entire home theater system is ensured.
