The ELAK-SPL HDLA is a massively multichannel, mobile/modular loudspeaker system with at least 256 individually addressable channels. It can be set up as a high-density loudspeaker array (HDLA) for High order ambisonics, Wavefield synthesis or beamforming applications.

16-32 4"-speakers form a module with computation/amplification electronics. The 3D-printed prototype enclosure design (currently 10x10x20cm) has a minimum frontal face for close grid spacing for line array/beamforming/WFS applications.
