What is a real 3D sound? A real 3D sound should make you feel you are actually there. In real life, when someone plays a guitar in a room, you will hear the guitar sound coming from 2 sources:

1.   Directly coming from the guitar – Sound stage and imaging
2.   Reflection from the walls in the room – Sound space of room acoustic

Only when you hear these two types of sound, you can feel the actual 3D sound space in the room. 

 

However, most of the 3D speaker could only give you an artificial 3D sound, not a real 3D sound. They could not deliver the two types of sound. They only spread the sound image or divert 360o sound beam, sound space of room shape is totally destroyed and sound imaging is distorted seriously.

 

A real 3D sound should retain the actual sound stage and imaging, and combine 3-dimensional multi-reflection sound to extend the room acoustic. When you are sitting in a small room and close your eyes, you should feel you are sitting in a concert hall, bigger than your sitting area, with performer in front of you, sound is diffusing into your ears from all directions.

We create a real 3D sound solution. 2 pairs of speaker are used: The main speaker pair is a high quality speaker to reproduce stereo sound stage with accurate sound imaging. The side speaker pair creates the sound space effect. Side speaker is pointing upward to build a vertical sound plane, a diffused sound immerse you, which is orthogonal to the main speaker horizontal sound plane. Sound coming out from the 3D effect side speaker has time delay to simulate the sound propagation delay in concert hall, and an equalizing filter to simulate the wall reflections over the audio spectrum.

Unlike the artificial 3D sound from the sound bar, you can feel the real 3D sound effect from anywhere in your room. You can also change 3D sound space effect to : room, studio and hall.
