Decades of research into the sound perception of the human hearing lead to the conclusion that concentric speakers are ideal for immersive audio reproduction.  

High-performance professional point-source drive units are an absolute prerequisite for the time-coherent dynamic reproduction of audio signals. Combined with the most advanced digital electronics it creates an unmatched immersive cinematic experience with unlimited dynamics. In modern movies where LFE bass can extend down to 3Hz, the second most important speakers are woofers and subwoofers which reproduce tight infrasonic bass. AIA perfected this group of speakers like no other company to give the tightest punchiest lowest bass reproduction ever.
