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 )	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 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 @ Standard Volume (80 dB) is less than standard deviation (<2 dB).
