As lifestyles have changed in this new normal, many people are spending more time at home with their families. Within this new lifestyle, the theatre bar system "8A-C22CX1" aims to provide an immersive sound quality at home that matches the high-definition visual quality of 8K broadcasting. In order to realize a stereophonic system at home, we adopted a new technology called "OPSODIS" that creates 360-degree stereophonic sound, including front and rear, left and right, and up and down, using only a front speaker and a subwoofer. With this simple system, the user can experience a powerful and immersive experience like no other at home.
