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) soundstage has good focus overall but but some sound tracks seem to be bit more diffused and lack separation.
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 rear channel (7.1 channel) but surround content produced by side-firing speakers on the bar is quite impressive and sounds seem to be coming from above you, behind you and on the sides.
Streo Dynamics ( Loudness ): Dynamic Range Compression @ Max Volume is little bit less than standard deviation (<2 dB) and maximum valume is more then 92 dB SPL
Audio & Video Latency Here no visible latency via ARC (33 ms) and Optical (65 ms) but visuals difference may found via Full HDMI Input (N/A).
