What is High-Resolution Audio?
High-Resolution Audio refers to a collection of digital processes allowing the encoding and playback of music using higher sampling rates than those used in CDs.
S-Master HX digital amplifier
Our S-Master HX amplifier is digital, eliminating analog components to reduce noise levels in the feedback stage for ultimate audio clarity.
Digital Sound Enhancement Engine HX
Even music from online streaming services can be upscaled by DSEE HX™ to produce rich sound closer to High-Resolution Audio.
From game mode to movie or music mode, ClearAudio+ automatically adjusts sound settings to suit whatever you're watching or listening to.
Engineered for exceptional sound
From speaker construction to fine-tuned audio technologies, every element of the HT-ST9 has been engineered to deliver the highest possible sound quality.
Precise, full-range sound
The woofer and tweeter are housed within a single speaker unit, utilizing separate drivers to reproduce a full range of sound that perfectly supports High-Resolution Audio playback.
Clear, natural highs
Super tweeters ensure high-frequency notes are reproduced with outstanding natural clarity and detail, so you'll enjoy pristine highs across music and dialogue.
Rigid carbon fiber diaphragm
A sturdy carbon fiber diaphragm responds quickly to mid and high frequencies with less distortion, improving sound reproduction across the entire frequency range.
Magnetic fluid technology
Magnetic fluid technology replaces conventional speaker dampers for better signal transfer, reducing distortion for high-quality sound from a smaller speaker.
