Een speaker is voortaan voldoende
Patented SDA® Surround technology
Our patented SDA® Surround technology means there’s no need to install rear speakers. SDA Surround creates a completely immersive 5 channel surround experience, as if there were dozens of speakers all around you. This technology is based on fundamental research into the way our ears process sound and perceive the direction of sounds.
