The Proof Is in the Testing

The Klippel Near Field Scanner (NFS) System was used for the development of Holoplot's X1 Matrix Array compensation algorithms, which was the topic of an article in the September 2022 issue of audioXpress. This joint article by Holoplot and Klippel offers a deep dive into the one of the many benefits of the innovative technology from the Berlin, Germany-based company.

Holoplot is a Berlin, Germany-based pro audio company and manufacturer of innovative 3D professional audio technology, the X1 Matrix Array. X1 is made up of two audio modules-Modul 96 (MD96), a two-way module integrating 96 drivers in a two layered matrix design, and Modul 80-S (MD80-S), a three-way module with 80 drivers in its first two matrix layers and a sensor-controlled subwoofer driver in its third layer. This matrix arrangement of loudspeaker drivers of different sizes-in a unique multi-layered configuration-enables control over sound propagation across a large frequency range, while providing the SPL and quality desired for high-performance sound reproduction.

Opposed to conventional loudspeakers relying mostly on hardware design, X1 is software driven, combining Wave Field Synthesis and 3D Audio-Beamforming to achieve authentic sound localization and complete control over the beam shape. It's the first sound system to decouple sound from its source, enabling the positioning of virtual loudspeakers within a space, creating sonic freedom for the user and exceptional experiences for the audience. X1 is able to generate multiple simultaneously running sound fields, each with its own content, level, shape, and position-all generated from as little as one module.

To develop such complex solutions, a balance between simulation and measurement during the development process is key to ensure continuous verification and improvement of the models and algorithms as well as the enhancement of sound quality. This process requires an extremely advanced measurement solution, which is why Holoplot turned to Klippel for its expertise.
