Audio Quality ( Tested )

Dialogue & Vocal Accuracy Frequency deviation from target is less than standard error (3.4 dB ); which means soundbar is very good to reproduce dialog and instrumental music
Bass Accuracy ( for music, film scores, movies, and games) Soundbar 's Low-Frequency-Extension is more than 35 Hz. Which means It can reproduce the deep thump and rumble in the low-bass accurately.
3- Dimensional Sound Accuracy ( Sound Stage) audio seems to be coming from a more accurate pinpoint location
Total Harmonic Distortion ( Center Channel ) It has dedicated center channel speaker and Total Harmonic Distortion of center channel @80dB is less than standard value(>0.7). So soundbar produce more clear and accurate audio of the dialogue in movies.
Surround Sound Imaging ( Rear Channel ) No dedicated or alternative channel for surround content. So it downmixes surround content to stereo.
Streo Dynamics ( Loudness ): Dynamic Range Compression @ Max Volume is less than standard deviation (<2 dB) and maximum valume is more then 92 dB SPL
