The SPL Ultra series inherits features from the established and award-winning DD series, which became known as the world's first subwoofer series with automatic room measurement.


Velodyne continues the concept of the DD series in the SPL Ultra. All aspects of the design have been carefully developed and perfected, from the housing with increased rigidity, to the digital amplifier with optimised circuits, to the drivers and the acoustic response.
