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 less than 35 Hz. Which means It can reproduce the deep thump and rumble in the low-bass accurately.
3- Dimensional Sound Accuracy ( Sound Stage) soundstage has good focus overall but but some sound tracks seem to be bit more diffused and lack separation.
Total Harmonic Distortion ( Center Channel ) No Dedicated Center Channel Speaker. So, it can not produce sound quite as clear as 3.0, 3.2 , 5.1 or 7.2 channels Soundbar. But It has decent center performance to produce accurate audio and dialogue.
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 little bit more than standard deviation (<2 dB) and maximum valume is over 92 dB SPL
Audio & Video Latency Here no visible latency via ARC (ARC @ 124 ms) and Optical (149 ms) but visuals difference may found via Full HDMI Input (168 ms).
