With the Samsung soundbars with SpaceFit Sound, you hear a room-filling sound. This technology scans how the audio sounds in your room. It does so with a built-in microphone in the soundbar. This way, it scans whether you have a lot of furniture or whether you're in an empty room. You have little noise reduction from furniture in an empty room, so sound quickly sounds loud. With this information, the soundbar adjusts the sound to the room. This way, you always hear a full sound and it doesn't sound too loud.
