How Does it Work?

A PSB system uses an array of loudspeakers deployed in the environment together with Silentium’s advanced signal processing algorithm. PSB results in focused sound transmission towards the desired zone, while minimizing the sound intensity elsewhere.

Applying several PSBs in a homogeneous environment(no partitions) such as a room or car results in a respective number of sound zones with independent audio content. Each listener can enjoy his own choice of music.

Layout: 4 door woofers + 4 ceiling twitters per zone.
