Matrix M4

The Matrix is the new paradigm in sound architecture. This speaker anticipates on the request for a high-end Home Cinema speaker system in a complete new way. The main point for this design was to use the possibility to aim sound. Several studies have been done on how to create a system that could fill up any room with high-end sound.

This resulted in a hanging speaker almost completely made out of aluminium. Its direction can be adjusted by rotation over a vertical and over a horizontal axis. Multiple High Frequency unit array gives projection control of sound minimising unwanted reflections. The depth of the speaker can be adjusted by changing the length of the rod, the speaker hangs on.

The Matrix M4 is available as high-end active or passive version. The Matrix M4 can perfectly be used as a front speaker in a system with the Matrix M2 as rear- or side-speaker.
