…..We want to listen to music with the best sound quality….. 

 With this in mind, we have continued our research and development for many years. 

We have now invented the world’s first CRSS (krɔ’ s) technology and developed the CRSS speaker.

CRSS is an acronym for Concave Reflection Speaker System. 

The CRSS structure converts the sound waves 

radiated inside the speaker box into 100% sound pressure and muffles the sound.

Since there are no reflected sound waves from inside the speaker box,

the sound waves radiated to the listener are extremely low distortion and

reproduce a high-precision stereo image with overwhelmingly high sound quality.
